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…
On the Low Progenitor Mass of the Binary Pulsar J0737-3039B
Tsvi Piran, Nir J. Shaviv
The observed orbital parameters of the recently discovered binary pulsar J0737-3039 are used to constrain the progenitor system. In particular, the small observed eccentricity and…
The Jet Angular Profile and the Afterglow Light Curves
Jonathan Granot, Pawan Kumar, Tsvi Piran
We investigate how the angular structure of GRB jets effects the afterglow light curves at different viewing angles, , from the jet symmetry axis. A numerical hydrodynamical…
How to Construct a GRB Engine?
Tsvi Piran, Ehud Nakar
According to the fireball model GRBs are produced when a relativistic flow is dissipated by shocks. The questions how does a GRB's "inner engine" accelerates and collimated the rel…
The Energy Distribution of Long Duration GRBS
Tsvi Piran, Pawan Kumar, Alin Panaitescu +1
The energy release in gamma-ray bursts is one of the most interesting clues on the nature of their "inner engines". We show here that the total energy release in GRBs varies by les…
Gravitational Radiation from Gamma-Ray Bursts
Tsvi Piran
Gamma Ray Bursts (GRBs) are the most relativistic objects known so far, involving, on one hand an ultra-relativistic motion with a Lorentz factor and on the other hand an…
