4. Cosmic Explosions...

Cosmic Explosions and Electromagnetic Transients: SNe, GRBs, TDEs

Explosive events in the cosmos release immense amount of energies, leading to various observable electromagnetic (EM) transients.  They offer a window into some of the most violent processes in the universe. This mini-symposium will gather experts in both theory and observation, and delve into the intricate phenomena of Supernovae (SNe), Gamma-Ray Bursts (GRBs), Fast Blue Optical Transients (FBOTs), Tidal Disruption Events (TDEs), Quasi-Periodic Eruptions (QPEs) and other similar explosive events. Related topics such as the evolution of massive stars and degenerate binaries,  and the dynamical processes around supermassive black holes, will also be covered. By examining these phenomena, we aim to gain new insights into the inner workings of stars, black holes, and other celestial bodies, and uncover new knowledge about their origins and evolution.

This mini-symposium will include a number of solicited talks, contributed talks and posters. Note that topics related to neutron stars (such as FRBs) will be covered in a different mini-symposium.

The deadlines for abstract submission and registration are the same as the general symposium, and can be found in

Invited/solicited speakers:  Kate Alexander,  Andrei Beloborodov, Jane Dai,  Thierry Foglizzo, Kunihito Ioka, Hiroki Nagakura, Tsvi Piran, Robert Quimby, Elenora Troja,  Yuhan Yao, Xiaofeng Wang, Eli Waxman, Binbin Zhang.
