‘Gamma ray bursts and Ic-BL supernovae‘
Supernova are stellar explosions so energetic they can briefly outshine an entire galaxy, radiating as much energy in a short amount of time as an ordinary star like the Sun is expected to emit over its 10 billion-year life span.
The connection between gamma-ray bursts (GRBs) and broad-line Ic (Ic-BL) supernovae (SNe) is now well established, with over 60 events discovered so far. This talk will present a history of this field before discussing the current state of the art in GRB-SN science. In particular I will focus on the role of jets in Ic-BL supernovae, especially their impact on the velocities of these events. I will also explain what the evolution of the supernova velocity can tell us about the types of GRB-SN that may exist.
For our March meeting we are delighted to have UCD PhD student Gabriel Finneran present an interesting talk on “Gamma ray bursts and Ic-BL supernovae”.
Gabriel Finneran is a PhD student in the UCD Space Science group. He recently defended his PhD thesis on the connection between gamma-ray bursts and Ic-BL supernovae. He has also worked on Ireland’s first satellite, EIRSAT-1, since 2020, and is now part of the operations team communicating with the spacecraft on a daily basis from UCD
