No supernovae associated with two long-duration gamma ray bursts
Johan P. U. Fynbo, Darach Watson, Christina C. Thoene +28
It is now accepted that long duration gamma-ray bursts (GRBs) are produced during the collapse of a massive star. The standard "collapsar" model predicts that a broad-lined and lum…
Three intervening galaxy absorbers towards GRB060418: faint and dusty?
Sara L. Ellison, Paul Vreeswijk, Cedric Ledoux +8
We present an analysis of three strong, intervening Mg II absorption systems (z_abs = 0.603, 0.656, 1.107) towards the optical afterglow of gamma-ray burst (GRB) 060418. From high…
Short timescale variability in the Faint Sky Variability Survey
L. Morales-Rueda, P. J. Groot, T. Augusteijn +3
We present the V band variability analysis of the point sources in the Faint Sky Variability Survey on time scales from 24 minutes to tens of days. We find that about one percent o…
Physics of the GRB 030328 afterglow and its environment
E. Maiorano, N. Masetti, E. Palazzi +30
We report on the photometric, spectroscopic and polarimetric, monitoring of the optical afterglow of Gamma-Ray Burst (GRB) 030328 detected by HETE-2. Photometry, collected at 7 dif…
Long gamma-ray bursts and core-collapse supernovae have different environments
A. S. Fruchter, A. J. Levan, L. Strolger +30
When massive stars exhaust their fuel they collapse and often produce the extraordinarily bright explosions known as core-collapse supernovae. On occasion, this stellar collapse al…
An optical supernova associated with the X-ray flash XRF 060218
E. Pian, P. A. Mazzali, N. Masetti +42
Long-duration gamma-ray bursts (GRBs) are associated with type Ic supernovae that are more luminous than average and that eject material at very high velocities. Less-luminous supe…
