The prompt, high resolution spectroscopic view of the "naked-eye" GRB080319B

V. D'Elia, F. Fiore, R. Perna +21

GRB080319B reached 5th optical magnitude during the burst prompt emission. Thanks to the VLT/UVES rapid response mode, we observed its afterglow just 8m:30s after the GRB onset whe…

The afterglow onset for GRB060418 and GRB060607A

S. Covino, S. D. Vergani, D. Malesani +32

Gamma-ray burst are thought to be produced by highly relativistic outflows. Although upper and lower limits for the outflow initial Lorentz factor are available, observationa…

GRB 070311: a direct link between the prompt emission and the afterglow

C. Guidorzi, S. D. Vergani, S. Sazonov +30

We present prompt gamma-ray, early NIR/optical, late optical and X-ray observations of the peculiar GRB 070311 discovered by INTEGRAL, in order to gain clues on the mechanisms resp…

Simultaneous Swift and REM monitoring of the blazar PKS0537-441 in 2005

E. Pian, P. Romano, A. Treves +24

The blazar PKS0537-441 has been observed by Swift between the end of 2004 and November 2005. The BAT monitored it recurrently for a total of 2.7 Ms, and the XRT and UVOT pointed it…

REM near-IR and optical multiband observations of PKS2155-304 in 2005

A. Dolcini, F. Farfanelli, S. Ciprini +23

Spectral variability is the main tool for constraining emission models of BL Lac objects. By means of systematic observations of the BL Lac prototype PKS 2155-304 in the infrared-o…

REM observations of GRB 060418 and GRB 060607A: the onset of the afterglow and the initial fireball Lorentz factor determination

E. Molinari, S. D. Vergani, D. Malesani +32

Gamma-ray burst (GRB) emission is believed to originate in highly relativistic fireballs. Currently, only lower limits were securely set to the initial fireball Lorentz factor Gamm…
