MWL observations of GRBs
Over the past five years, six long gamma-ray bursts (GRBs) have been found to have very high energy (VHE, >100 GeV) 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 a brief overview of what we have learnt from the synchrotron afterglows of five VHE GRBs (including results from Rhodes et al. 2020, 2022; Giarratana, Rhodes et al. 2022 and Bright, Rhodes et al. submitted); 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.
