    Explanation: To play on Carl Sagan’s famous words "If you wish to make black hole jets, you must first create magnetic fields." The featured image represents the detected intrinsic spin direction (polarization) of radio waves. The polarizationi is produced by the powerful magnetic field surrounding the supermassive black hole at the center of elliptical galaxy M87. The radio waves were detected by the Event Horizon Telescope (EHT), which combines data from radio telescopes distributed worldwide. The polarization structure, mapped using computer generated flow lines, is overlaid on EHT’s famous black hole image, first published in 2019. The full 3-D magnetic field is complex. Preliminary analyses indicate that parts of the field circle around the black hole along with the accreting matter, as expected. However, another component seemingly veers vertically away from the black hole. This component could explain how matter resists falling in and is instead launched into M87’s jet.

    The ancient Antikythera mechanism is shown, the oldest known orrery. See Explanation.

    The Antikythera Mechanism

    Explanation: No one knew that 2,000 years ago, the technology existed to build such a device. The Antikythera mechanism, pictured, is now widely regarded as the first computer. Found at the bottom of the sea aboard a decaying Greek ship, its complexity prompted decades of study, and even today some of its functions likely remain unknown. X-ray images of the device, however, have confirmed that a main function of its numerous clock-like wheels and gears is to create a portable, hand-cranked, Earth-centered, orrery of the sky, predicting future star and planet locations as well as lunar and solar eclipses. The corroded core of the Antikythera mechanism's largest gear is featured, spanning about 13 centimeters, while the entire mechanism was 33 centimeters high, making it similar in size to a large book. Recently, modern computer modeling of missing components is allowing for the creation of a more complete replica of this surprising ancient machine.

    Three Tails of Comet NEOWISE
    Image Credit & Copyright: Nicolas Lefaudeux

    Explanation: What created the unusual red tail in Comet NEOWISE? Sodium. A spectacular sight back in the summer of 2020, Comet NEOWISE, at times, displayed something more than just a surprisingly striated white dust tail and a pleasingly patchy blue ion tail. Some color sensitive images showed an unusual red tail, and analysis showed much of this third tail's color was emitted by sodium. Gas rich in sodium atoms might have been liberated from Comet NEOWISE's warming nucleus in early July by bright sunlight, electrically charged by ultraviolet sunlight, and then pushed out by the solar wind. The featured image was captured in mid-July from Brittany, France and shows the real colors. Sodium comet tails have been seen before but are rare -- this one disappeared by late July. Comet C/2020 F3 (NEOWISE) has since faded, lost all of its bright tails, and now approaches the orbit of Jupiter as it heads back to the outer Solar System, to return only in about 7,000 years.

  • Searching for Higgs boson twins

    ParticleNews at 2021-02-25T16:27:38Z

    "Searching for Higgs boson twins"

    Higgs-boson pairs could help scientists understand the stability of our universe. The trick is finding them.

    Particle collision visualization

    In 2012, scientists on the CMS and ATLAS experiments at CERN’s Large Hadron Collider discovered the Higgs boson. Now, they’re looking for two Higgs bosons born from a single collision.

    “The Higgs self-coupling has implications in understanding the origin and ultimate fate of the universe,” says Nan Lu, a postdoc at the California Institute of Technology supported by the US Department of Energy’s Office of Science. “This process is a lighthouse that guides the future of particle physics.”

    Higgs bosons are the physical manifestations of the Higgs field, an invisible medium that is woven into the fabric of spacetime.

    “Elementary particles obtain their masses through interaction with this Higgs field,” Lu says. “Without the Higgs field, all elementary particles would be massless and traveling at the speed of light. The universe would not look the same as it does today.”

    The LHC can generate Higgs bosons by colliding protons and transmitting the stored energy into the Higgs field—much like a pebble striking the surface of a river and transferring its kinetic energy into a ripple. This process happens at a rate of about one in a billion collisions.

    On even rarer occasions, this energy transfer can generate not one but two Higgs bosons at the same time. These Higgs boson twins could help scientists characterize a largely unmeasured facet of the Higgs mechanism: the shape of the Higgs potential.

    The boson, the field and the Higgs potential

    The Brout-Englert-Higgs mechanism—to use its full name—consists of three interlinking facets: the Higgs boson, the Higgs field and the Higgs potential.

    “You can think about it like a river,” says Irene Dutta, a graduate student at Caltech. “The Higgs boson is a ripple, the Higgs field is the water, and the Higgs potential is the shape of the riverbed.”

    The Higgs boson—the ripple—gives scientists a glimpse of the otherwise invisible Higgs field—the water. But underneath it all is the Higgs potential—the riverbed, or a mathematical function that determines the different possible energy states of the Higgs field.

    “A river might seem calm and flat,” Dutta says, “but there could be a waterfall that leads to much lower ground that we cannot see from where we are.”

    If the potential dropped and the Higgs field spontaneously fell into a lower energy state, the universe as we know it would evaporate.

    “The current calculations indicate that we could be living in a false vacuum,” says Thong Nguyen, a graduate student at Caltech. “This means that at any moment, the Higgs field could tunnel through the potential barrier to a true negative-energy vacuum, creating an expanding singularity bubble that eventually swallows up the entire universe.”

    (The universe has yet to disappear in its 14 billion years, at least, and physicists do not anticipate that it will happen anytime soon.)

    The origin of matter

    According to Nguyen, the Higgs field has already fallen from a high energy state into a lower one once before.

    “Right after the Big Bang, when the universe was a hot and dense soup, the Higgs field was perfectly symmetrical and did not interact with other particles,” Nguyen says. “But as the universe cooled, the Higgs field underwent a phase transition. Symmetry broke, and then particles were able to interact with the Higgs field to acquire mass.”

    This first transition could be the missing link in one of the biggest mysteries in physics: the dominance of matter over its equal-and-opposite counterpart, antimatter.

    “Right after the Big Bang, we should have had equal amounts of matter and antimatter,” Lu says. “Today, there is a large amount of matter and almost no antimatter.”

    The evolution of the Higgs field during the primordial universe could be responsible for this imbalance.

    “If it’s a smooth transition, as our models predict, then the entire Higgs field would have cooled homogeneously, like water slowly freezing into ice,” Nguyen says. “But if it’s an abrupt transition, then bubbles could have formed and eventually expanded to fill the entire universe.”

    These bubbles in the Higgs field could have serendipitously sheltered the small excess of matter that eventually formed everything.

    Higgs self-coupling

    The Higgs potential regulates the behavior of Higgs bosons, including their interactions with one another. If scientists can find and study Higgs-boson pairs, then they can work backwards and indirectly probe the Higgs potential’s shape.

    “First we need to measure the rate of Higgs-boson pair production,” Lu says. “Then we want to measure the properties of these two Higgs bosons.”

    The scarcity of this process makes it a classic needle-in-a-haystack problem.

    “During Run II [which ended in December 2018], the LHC would have generated about 7.5 million Higgs bosons,” Dutta says. “But it would have only produced about 4500 Higgs-boson pairs.”

    Higgs bosons are notoriously difficult to separate from look-alike subatomic processes. Even for a very clean signature—a Higgs boson decaying into two photons—there are 10 identical background events for every real Higgs boson.

    “We’re completely swamped by the background,” Dutta says. “The di-Higgs production process is not an easy observation to make and our best chance of seeing it is with the High-Luminosity LHC upgrade,” now in full progress. 

    Once this upgrade is completed later this decade, future runs will increase the total number of potential collisions scientists have to study by at least a factor of 10.

    The overall US contributions to the LHC experimental research program and HL-LHC upgrade are funded by the US Department of Energy and the National Science Foundation. With the HL-LHC only a few years away, scientists are already honing their analysis methods.

    They have begun to apply machine-learning techniques inspired by natural language processing. Nguyen is developing and training machine-learning algorithms to recognize the subtle differences between Higgs boson signatures and look-alike background processes (much like a natural-language-processing algorithm separates similar sounding words like “close” and “clothes.”)

    “We can treat each particle like a word in a sentence,” Nguyen says.

    Currently, scientists are working with only a few signatures for Higgs-boson pairs, but they hope to study more complex signatures over the next few years.

    “This research is still in the early stages but moving very fast,” Lu says.

    A Venus Flyby

    Explanation: On a mission to explore the inner heliosphere and solar corona, on July 11, 2020 the Wide-field Imager on board NASA's Parker Solar Probe captured this stunning view of the nightside of Venus at distance of about 12,400 kilometers (7,693 miles). The spacecraft was making the third of seven gravity-assist flybys of the inner planet. The gravity-asssist flybys are designed to use the approach to Venus to help the probe alter its orbit to ultimately come within 6 million kilometers (4 million miles) of the solar surface in late 2025. A surprising image, the side-looking camera seems to peer through the clouds to show a dark feature near the center known as Aphrodite Terra, the largest highland region on the Venusian surface. The bright rim at the edge of the planet is nightglow likely emitted by excited oxygen atoms recombining into molecules in the upper reaches of the atmosphere. Bright streaks and blemishes throughout the image are likely due to energetic charged particles, and dust near the camera reflecting sunlight. Skygazers from planet Earth probably recognize the familiar stars of Orion's belt and sword at lower right.

    Perseverance: How to Land on Mars
    Image Credit: NASA, JPL, Mars 2020

    Explanation: Slung beneath its rocket powered descent stage Perseverance hangs only a few meters above the martian surface, captured here moments before its February 18 touchdown on the Red Planet. The breath-taking view followed an intense seven minute trip from the top of the martian atmosphere. Part of a high resolution video, the picture was taken from the descent stage itself during the final skycrane landing maneuver. Three taut mechanical cables about 7 meters long are visible lowering Perseverance, along with an electrical umbilical connection feeding signals (like this image), to a computer on board the car-sized rover. Below Perseverance streamers of martian dust are kicked-up from the surface by the descent rocket engines. Immediately after touchdown, the cables were released allowing the descent stage to fly to a safe distance before exhausting its fuel as planned.

    Swiss Alps, Martian Sky
    Image Credit & Copyright: Jens Bydal

    Explanation: Taken on February 6, this snowy mountain and skyscape was captured near Melchsee-Frutt, central Switzerland, planet Earth. The reddish daylight and blue tinted glow around the afternoon Sun are colors of the Martian sky, though. Of course both worlds have the same Sun. From Mars, the Sun looks only about half as bright and 2/3 the size compared to its appearance from Earth. Lofted from the surface of Mars, fine dust particles suspended in the thin Martian atmosphere are rich in the iron oxides that make the Red Planet red. They tend to absorb blue sunlight giving a red tinge to the Martian sky, while forward scattering still makes the light appear relatively bluish near the smaller, fainter Martian Sun. Normally Earth's denser atmosphere strongly scatters blue light, making the terrestrial sky blue. But on February 6 a huge cloud of dust blown across the Mediterranean from the Sahara desert reached the Swiss Alps, dimming the Sun and lending that Alpine afternoon the colors of the Martian sky. By the next day, only the snow was left covered with reddish dust.

  • New strategy for Latin American physics

    ParticleNews at 2021-02-16T16:28:04Z

    "New strategy for Latin American physics"

    Scientists in Latin America recently published the first coordinated plan for the region’s research in high-energy physics, astrophysics and cosmology.

    Illustration: LASF4RI labeled watering can fostering science in South America

    Latin American scientists have completed their roadmap for the next five years of physics research, marking the end of a two-year grassroots effort to plan for the future of experiments and partnerships in the region.

    “One of the main goals was to find where collaboration could generate more impact for Latin American contributions to physics,” says Marcela Carena, head of the Theoretical Physics Department at the US Department of Energy’s Fermi National Accelerator Laboratory. “At this moment, there’s been no other Latin American body to guide such a strategic plan for the scientific community.”

    Carena, originally from Argentina, was one of the 23 members of the Latin American Strategy Forum for Research Infrastructure (LASF4RI) preparatory group, the team responsible for collecting input from the Latin American and international theoretical and experimental physics community in three pilot areas of research: high-energy physics, astrophysics and cosmology. The scientists on the team represented 10 countries in the region—Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Mexico, Peru, Paraguay and Venezuela—as well as Japan, Europe (as represented by CERN) and the United States.

    A plan for science and infrastructure

    The final report contains 10 recommendations, beginning with a push for continued support of current and future projects in cosmology and astrophysics, ranging from those already in operation—such as Pierre Auger Observatory in Argentina—and those planned for the near-term—such as the BINGO telescope in Brazil and Vera Rubin Observatory in Chile—to those planned for start-up more than a decade from now—such as the South American Gravitational-Wave Observatory. 

    Latin America is known for its clear skies and powerful telescopes; it provides the location for crucial observations that form many astrophysics and cosmology experiments. 

    “There are a series of projects that are already being built in Latin America and will become operational in 2025 or 2026,” says Marta Losada, originally from Colombia and more recently a professor of physics and the dean of science at New York University Abu Dhabi, who chaired the preparatory group. “So that’s a high priority.”

    Another high priority named in the report is ANDES, an underground laboratory proposed to be built in a tunnel connecting Argentina and Chile. The laboratory, protected from cosmic radiation that hits the planet’s surface, would allow scientists around the world to investigate dark matter and neutrinos, as well as conduct experiments in biology and geology. 

    “You need to start building the capacity and the expertise for those experiments now, if you want to build them in the region,” Losada says.

    The strategy identifies as areas of strength for the Latin American high-energy physics community both its involvement in collider physics, through international experiments at the Large Hadron Collider at CERN, and its involvement in neutrino physics, through the international Deep Underground Neutrino Experiment, managed by Fermilab. 

    “This is important for both Europe and the United States, because Latin American scientists have been contributing for decades,” Carena says. “But this plan will allow a higher level of coordination and will allow Latin American scientists to be better contributors to international large-scale experiments.”

    The report also describes the need to improve the region’s computing infrastructure and internet connectivity. The report says it is “fundamental to all experimental efforts” and will help scientists process the vast amounts of data generated at research sites, such as the under-construction Vera Rubin Observatory and the planned Cherenkov Telescope Array, both in Chile.

    Support for stronger connections

    By developing research infrastructure, encouraging global scientific participation and offering training opportunities, the report authors write that these efforts will help inspire future Latin American scientists and work to impede the “‘brain draining effect’ in the region.” 

    The LASF4RI group also mentioned the need to help scientists align their research with funding options, which can be tough to navigate. “Latin America is a complex environment with many countries and many different funding agencies,” Carena says.

    Prior to publishing the final report, the authors presented their recommendations to government officials and leaders of funding agencies in Latin America on October 27, 2020. Afterward, the officials at the fourth Iberoamerican Science and Technology Ministerial Meeting issued a declaration.

    Carena says the declaration provides national and international validation for the work of local scientists, labs and universities. Losada adds that “it was important to reflect the size of the growing community of Latin American physicists, and for us to demonstrate how you should continue to protect that investment in knowledge and resources.”

    A regional roadmap

    Latin American physicists began brainstorming what might go into a formal regional strategy—inspired by the longer-term plans developed for Europe and the United States—at professional conferences going back to 2016. And in early 2019, LASF4RI held its first workshops to create such a plan

    “Before this, we really hadn’t even worked out our main areas of research in Latin America or our strengths very clearly. These are really important, deep questions,” Losada says.

    Through extensive consultation and meetings, the team worked with physicists across disciplines to come up with the final recommendations. In 2020, the committee adjusted their meetings as the pandemic forced them to replace international in-person gatherings with Zoom calls.

    The preparatory group reached out to scientific societies, gathered 40 scientific white papers, and then submitted a draft report to a high-level review by scientists outside the preparatory group. 

    With an endorsement from the reviewers, the LASF4RI group finalized their report in November 2020.

  • Dr. Nigel Smith appointed as next Director of TRIUMF

    ParticleNews at 2021-02-12T16:27:45Z

    "Dr. Nigel Smith appointed as next Director of TRIUMF"

    Dr. Nigel Smith appointed as next Director of TRIUMF Press Releasexeno Fri, 02/12/2021 - 08:02521

    Dr. Nigel Smith

    VANCOUVER, B.C. – Dr. Nigel Smith, Executive Director of SNOLAB, has been selected to serve as the next Director of TRIUMF. Succeeding Dr. Jonathan Bagger, who departed TRIUMF in January 2021 to become CEO of the American Physical Society, Dr. Smith's appointment comes as the result of a highly competitive, six-month international search. Dr. Smith will begin his 5-year term as TRIUMF Director on May 17, 2021.

    "I am truly honoured to have been selected as the next Director of TRIUMF," said Dr. Smith. "I have long been engaged with TRIUMF's vibrant community and have been really impressed with the excellence of its science, capabilities and people. TRIUMF plays a unique and vital role in Canada's research ecosystem, and I look forward to continuing the legacy of excellence upheld by Dr. Jonathan Bagger and the previous TRIUMF Directors". 

    Founded in 1968, TRIUMF is Canada's particle accelerator centre. A multidisciplinary laboratory, TRIUMF is an international hub for discovery and innovation – pushing frontiers in research while training the next generation of leaders in science, medicine, and business. This breadth and impact are what attracted Dr. Smith to the role of Director, stating, "TRIUMF has an amazing portfolio of research covering fundamental and applied science that also delivers tangible societal impact through its range of medical and commercialisation initiatives. I am extremely excited to have the opportunity to lead a laboratory with such a broad and world-leading science program."

    "Nigel brings all the necessary skills and background to the role of Director," said Dr. Digvir Jayas, Interim Director of TRIUMF, Chair of the TRIUMF Board of Management, and Vice-President, Research and International at the University of Manitoba. "As Executive Director of SNOLAB, Dr. Smith is both a renowned researcher and experienced laboratory leader who offers a tremendous track record of success spanning the local, national, and international spheres. The Board of Management is thrilled to bring Nigel's expertise to TRIUMF so he may help guide the laboratory through many of the exciting developments on the horizon."

    Dr. Smith joins TRIUMF at an important period in the laboratory's history, as the organization moves into the second year of its current Five-Year Plan (2020-2025) and prepares to usher in a new era of science and innovation that will include the completion of two major projects: the Advanced Rare Isotope Laboratory (ARIEL) and the Institute for Advanced Medical Isotopes (IAMI). This new infrastructure, alongside TRIUMF's existing facilities and world-class research programs, will solidify Canada's position as a global leader in both fundamental and applied research. Dr. Smith expressed his optimism for TRIUMF, saying, "I am delighted to have this opportunity, and it will be a pleasure to lead the laboratory through this next exciting phase of our growth and evolution."

    About Nigel Smith

    Nigel Smith has served as SNOLAB as Director since July 2009. He currently holds a full Professorship at Laurentian University, adjunct Professor status at Queen's University, and a visiting Professorial chair at Imperial College, London. He received his Bachelor of Science in physics from Leeds University in the U.K. in 1985 and his Ph. D. in astrophysics from Leeds in 1991. He has served as a lecturer at Leeds University, a research associate at Imperial College London, group leader (dark matter) and deputy Division Head at the STFC Rutherford Appleton Laboratory before relocating to Canada to oversee the SNOLAB deep underground facility. 

    Dr. Smith has undertaken astroparticle physics research in extreme locations throughout his career, studying astronomical sources of ultra-high energy gamma rays using a telescope at the South Pole, searching for Galactic dark matter using detectors located 1100m underground at the Boulby facility in the U.K., and subsequently overseeing dark matter and neutrinos studies 2km underground at the SNOLAB facility in Canada. In 1987 he "wintered-over" as the sole operator of the telescope at the Amundsen-Scott South Pole station, being the first Briton to successfully winter at the Pole itself. 

    About TRIUMF 

    Established in 1968 in Vancouver, TRIUMF is Canada's particle accelerator centre. The lab is a hub for discovery and innovation inspired by a half-century of ingenuity in answering nature's most challenging questions.
