The Rates of Hypernovae and Gamma-Ray Bursts: Implications for their Progenitors
Ph. Podsiadlowski, P. A. Mazzali, K. Nomoto +2
A critical comparison of estimates for the rates of hypernovae (HNe) and gamma-ray bursts (GRBs) is presented. Within the substantial uncertainties, the estimates are shown to be q…
X-ray spectral diagnostics of the immediate environment of GRB 991216
D. R. Ballantyne, E. Ramirez-Ruiz, D. Lazzati +1
The recent report of iron line features in the afterglow of the gamma-ray burst (GRB) 991216 has important implications for the properties of the radiating material and hence the n…
Afterglow lightcurves, viewing angle and the jet structure of gamma-ray bursts
E. Rossi, D. Lazzati, M. J. Rees
Gamma ray bursts are often modelled as jet-like outflows directed towards the observer; the cone angle of the jet is then commonly inferred from the time at which there is a steepe…
