Uncovering the Nature of Gamma-ray Bursts with Radio Observations

Genevieve Schroeder, Cornell

Abstract: Gamma-ray bursts (GRBs) are amongst the most energetic explosions in space, and are typically divided into two categories based on their duration. Short GRBs (< 2 s) typically originate from neutron star mergers, whereas long GRBs (> 2 s) are coincident with the collapse of massive stars. Following the gamma-rays, emission is expected across the electromagnetic spectrum. The radio band is particularly important, as predicted emission can be detected for ~weeks to ~years, giving insight into explosion properties and the environments in which these GRBs occur. Additionally, radio searches on timescales of ~years to ~decades may reveal late rising radio emission, which would confirm several long-standing models of GRBs from both massive star collapse and neutron star mergers. I will highlight several of my radio focused projects that focus on GRBs and their analogs, as well as future directions.
