Radio Emission Hints At Structure In The Brightest Of All Time Gamma Ray Burst Outflow

Semester: Summer 2025


Presentation description

Gamma Ray Bursts (GRBs) are an astronomical class of the most powerful explosions, which often signal the birth of black holes from core collapse supernovae and neutron star mergers. The Brightest Of All Time (BOAT) is a GRB that, due to its high energy and close proximity, is observed in great detail, especially in the radio wavelength. Yet current models, which assume that the narrow cone of material spewed from the black hole is uniform in speed and energy, fail to explain its radio emission. We implement a new, more general, model that assumes the cone of material launched can take on a variety of shapes in speed and energy. The new model is a much better match for the radio data than current models and does not require the invocation of unphysical parameters. Future work will apply our implementation of the new model to other GRBs whose emission is similarly challenging to explain.
