Greg Walsh, a Graduate Research Assistant in Physics and Astronomy, and also the Center for Gravitational Waves and Cosmology, has been awarded a fellowship from the NASA WV Space Grant Consortium (WVSGC). The NASA WVSGC is a group of West Virginia academic institutions with industrial partners under the sponsorship of NASA. One of the primary components of its mission is to help build research infrastructure at its member institutions, along with awarding competitive seed grants to members.
Greg is an observational astronomer using multi-wavelength techniques to search for binary supermassive black holes and characterize their effects on galaxy evolution. He uses Very Long Baseline Interferometry (VLBI) to probe the smallest emission regions for direct searches of binaries, and a host of telescopes across the electromagnetic spectrum to analyze binary imprints on the smallest to galactic-scale environments. His work has strong multi-messenger implications for the low-frequency gravitational wave searches conducted by pulsar timing arrays, like NANOGrav.
