Lauren Rhodes (University of Oxford, UK), "The afterglows of VHE GRBs with focus on the BOAT"
Over the past five years, six long gamma-ray bursts (GRBs) have been found to have very high energy (VHE, >100GeV) counterparts. As a result of this discovery, it has become apparent that we have been missing half of the energy produced in the afterglow of long GRBs. The jet properties and environments of VHE GRBs vary hugely in a similar manner to that seen in the ‘regular’ long GRB population with evidence of bright reverse shock emission and multiple jet components. In this talk, I will present results of the most recent VHE GRB also known as the BOAT or GRB 221009A. I will also introduce the possibilities for studying VHE GRBs as a population of sources; and how the GRB community can work together to better understand these events.
