Experimental, Observational and Theoretical Astrophysics

Astrophysics research includes the detection and origin of galactic cosmic rays, X-rays, and gamma-rays, direct and indirect searches for dark matter, theoretical and observational studies of high-energy and transient phenomena, tests of the standard model of particle physics and physics beyond the standard model, cosmology, and plasma astrophysics. Results include the detection of the ⁶⁰Fe nucleosynthesis-clock isotope in galactic cosmic rays based on ACE-CRIS observations, the first constraints on the hard X-ray polarization of the accreting neutron star GX 301-2 with the X-Calibur hard X-ray polarimetry mission, detailed information about the temporal and spectral properties of the presumed neutrino bright blazar TXS 0506+056 with VERITAS, and extremely sensitive tests of Einstein’s Equivalence Principle.
