Gamma Ray Bursts: new rulers to measure the Universe
G. Ghirlanda, G. Ghisellini, D. Lazzati +1
The best measure of the Universe should be done using a standard "ruler" at any redshift. Type Ia Supernovae (SN Ia) probe the universe up to z1.5, while the Cosmic Microwave…
SN 2003lw and GRB 031203: A Bright Supernova for a Faint Gamma-ray Burst
D. Malesani, G. Tagliaferri, G. Chincarini +23
Optical and near-infrared observations of the gamma-ray burst GRB 031203, at z = 0.1055, are reported. A very faint afterglow is detected superimposed to the host galaxy in our fir…
The collimation--corrected GRB energies correlate with the peak energy of their spectrum
G. Ghirlanda, G. Ghisellini, D. Lazzati
We consider all bursts with known redshift and peak energy, . For a good fraction of them an estimate of the jet opening angle is available from the achromat…
The X-ray afterglow of GRB030329 at early and late times
A. Tiengo, S. Mereghetti, G. Ghisellini +3
Thanks to its extraordinary brightness, the X-ray afterglow of GRB030329 could be studied by XMM-Newton up to two months after the prompt Gamma-ray emission. We present the results…
