Uncovering the Nature of Gamma-ray Bursts with Radio Observations

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