Supernovae Powered by Collapsar Accretion in Gamma-Ray Burst Sources
Milos Milosavljevic, Christopher C. Lindner, Rongfeng Shen +1
The association of long-duration gamma-ray bursts (LGRBs) with Type Ic supernovae presents a challenge to supernova explosion models. In the collapsar model for LGRBs, gamma rays a…
Implications of electron acceleration for high-energy radiation from gamma-ray bursts
Rodolfo Barniol Duran, Pawan Kumar
In recent work we suggested that photons of energy >100 MeV detected from GRBs by the Fermi Satellite are produced via synchrotron emission in the external forward shock with a wea…
Supernovae-induced accretion and star formation in the inner kiloparsec of a gaseous disk
Pawan Kumar, Jarrett L. Johnson
We consider the effects of supernovae (SNe) on accretion and star formation in a massive gaseous disk in a large primeval galaxy. The gaseous disk we envisage, roughly 1 kiloparsec…
