Are low luminosity GRBs generated by relativistic jets?
low luminosity generated relativistic jets
2011/9/29
Low luminosity gamma-ray bursts (ll-GRBs) constitute a sub-class of gamma-ray bursts (GRBs) that plays a central role in the GRB-supernova connection. While ll-GRBs differ from typical long GRBs (LGRB...
Rotating BHs as Central Engines of Long GRBs: Faster is Better
Rotating BHs Central Engines
2011/1/10
We performed simulations of collapsars with different Kerr parameters a=0, 0.5, 0.9, 0.95. It is shown that a more rapidly rotating black hole is driving a more energetic jet. No jet is seen for the c...
Massive Oe/Be stars at low metallicity: Candidate progenitors of long GRBs?
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
At low metallicity the B-type stars rotate faster than at higher metallicity, typically in the SMC. As a consequence, it was expected a larger number of fast rotators in the SMC than in the Galaxy, in...
The GRBs Hubble diagram in quintessential cosmological models
Cosmology and Extragalactic Astrophysics (astro-ph.CO)

It has been recently empirically established that some of the directly observed pa- rameters of GRBs are correlated with their important intrinsic parameters, like the luminosity or the total radiated...

Gamma-Ray Bursts Large Area Telescope Gamma-ray Burst Monitor
2010/3/9
We present the analysis results of three Gamma-Ray Bursts (GRBs) detected by the Gamma-ray Burst Monitor (GBM) and the Large Area Telescope (LAT) onboard Fermi: the two long GRB 080825C and GRB 090217...
