The metamorphosis of Supernova SN2008D/XRF080109: a link between Supernovae and GRBs/Hypernovae
Paolo A. Mazzali, Stefano Valenti, Massimo Della Valle +38
The only supernovae (SNe) to have shown early gamma-ray or X-ray emission thus far are overenergetic, broad-lined Type Ic SNe (Hypernovae - HNe). Recently, SN 2008D shows several n…
Bohdan's Impact on Our Understanding of Gamma-ray Bursts
Tsvi Piran
Bohdan Paczy'nski was one of the pioneers of the cosmological GRB model. His ideas on how GRBs operate and what are their progenitors have dominated the field of GRBs in the hectic…
A Canonical High Energy Afterglow Emission Light Curve?
Yi-Zhong Fan, Tsvi Piran
We present self consistent calculations of Synchrotron self Compton (SSC) radiation that takes place within the afterglow blast wave and External inverse Compton (EIC) radiation th…
High Energy Afterglow from Gamma-ray Bursts
Yi-Zhong Fan, Tsvi Piran, Ramesh Narayan +1
We calculate the very high energy (sub-GeV to TeV) inverse Compton emission of GRB afterglows. We argue that this emission provides a powerful test of the currently accepted afterg…
Do long-duration GRBs follow star formation?
Dafne Guetta, Tsvi Piran
We compare the luminosity function and rate inferred from the BATSE long bursts peak flux distribution with those inferred from the Swift peak flux distribution. We find that both…
A Note on "Probing the existence of the - correlation in long Gamma Ray Bursts" by Ghirlanda et al. - astro-ph/0502186
Ehud Nakar, Tsvi Piran
In Nakar & Piran (2004) we have shown that a large fraction of BATSE bursts cannot satisfy the Amati relation between the isotropic energy - peak energy of GRBs. Our results have b…
