Saori Pastore, assistant professor of physics in Arts & Sciences at Washington University in St. Louis, helps explain what happens in nuclei when they decay, scatter among each other or come into contact with subatomic particles. Her recent paper, “Weak Transitions in Light Nuclei,” published in Frontiers in Physics, contributes to a body of increasingly accurate, descriptive calculations of nuclear structure and reactions.
Li Yang, professor of physics in Arts & Sciences, conducted research with black phosphorus — a material with a thickness of just a few atomic layers — in a study that is hailed as a milestone of the past 50 years by the Physical Review B, an academic journal of the American Physical Society.
Researchers from physics and chemistry in Arts & Sciences at Washington University in St. Louis leveraged data from nuclear scattering experiments to make stringent constraints on how neutrons and protons arrange themselves in the nucleus. Their predictions are tightly connected to how large neutron stars grow and what elements are likely synthesized in neutron star mergers.
The behavior of electrons determines the fundamental properties of any material, such as its ability to conduct electricity. Erik Henriksen, assistant professor of physics in Arts & Sciences, takes advantage of strange-but-true qualities of graphene to search for correlated motion of electrons.
Bhupal Dev, assistant professor of physics in Arts & Sciences at Washington University in St. Louis, proposes a new way to leverage data from ultra-high energy neutrinos from large neutrino telescopes such as the IceCube Neutrino Observatory in Antarctica.
Presolar grains — tiny bits of solid interstellar material formed before the sun was born — are sometimes found in primitive meteorites. But a noble gas analysis from physicists in Arts & Sciences reveals evidence of presolar grains in part of a meteorite where they are not expected to be found.
A balloon-borne scientific instrument designed to study the origin of cosmic rays is taking its second turn high above the continent of Antarctica three and a half weeks after its launch.
A team of Washington University in St. Louis scientists at McMurdo Station, Antarctica, successfully launched its SuperTIGER (Super Trans-Iron Galactic Element Recorder) instrument, which is used to study the origin of cosmic rays.
Researchers from Washington University in St. Louis will develop and deploy a new telescope designed to measure the linear polarization of X-rays arriving from distant neutron stars, black holes and other exotic celestial objects. The instrument will be flown on a minimum of two scientific balloon launches as early as summer 2021. The NASA-funded effort builds on promising results from a previous balloon-borne mission known as X-Calibur and is dubbed XL-Calibur.
Under a five-year, $7 million cooperative agreement led by Jeffrey Gillis-Davis, research associate professor of physics in Arts & Sciences, researchers will investigate fundamental questions at the intersection of space science and human space exploration.
