For the first time, a team of scientists has used the orientation of light left over from the early universe to detect gravitational lensing from galaxy clusters – the bending of light around these massive objects. Using gravitational lensing data taken by the South Pole Telescope and the Dark Energy Camera, Fermilab scientist Brad Benson and colleagues have demonstrated a new way to “weigh” galaxy clusters and ultimately shed light on dark matter, dark energy and other mysteries of the cosmos.
Fermilab features
The American Physical Society Division of Particles and Fields has given its 2019 Early Career Instrumentation Award to two scientists on the international Deep Underground Neutrino Experiment, hosted by Fermilab. Ana Amelia Machado and Ettore Segreto, both of the University of Campinas in Brazil, are recognized for inventing and developing a photon sensor that is currently a baseline technology for the DUNE particle detector.
Spack, a software package management tool, was recognized with an R&D 100 Award in November. Developed for high-performance computing applications, Spack is used as an end-to-end development tool within the high-energy physics community. Fermilab is a contributor to Spack, whose initial development was led by Lawrence Livermore National Laboratory.
Scientists on Fermilab’s MicroBooNE experiment have measured neutrino interactions on argon with unprecedented statistics and precision using data on the resultant muons — in particular, the muon’s momentum and angle. The experiment features the first liquid-argon time projection chamber with the resolution and statistics to carry out such a measurement. Researchers will use the result to improve simulations of neutrino interactions. These improvements are important for neutrino experiments in general, including the Short-Baseline Neutrino program experiments and the international Deep Underground Neutrino Experiment, both hosted by Fermilab.
In November, the Chicago Quantum Exchange held a workshop about ethics and societal impacts of artificial intelligence and quantum computing technologies. Participants from a wide variety of academic backgrounds, from physicists to sociologists, discussed the implications of technology on society and vice versa and identified critical steps scientists need to take so technology is developed and implemented ethically and responsibly.
The results are out: According to a just-released economic impact study, Fermilab provides substantial benefits for the state of Illinois. It has directly and indirectly generated millions of dollars for Illinois households, businesses and the state. The total annual economic impact in Illinois came to $452 million.
Currently a councilor of the American Physical Society Forum on International Physics, Barzi is adding to her contributions to APS. Her memberships in the APS Council committees reflect her commitment to promote knowledge of physics throughout the U.S. and the world.
