GRB 110715A: The peculiar multiwavelength evolution of the first afterglow detected by ALMA

R. Sánchez-Ramírez, P. J. Hancock, G. Jóhannesson +35

We present the extensive follow-up campaign on the afterglow of GRB 110715A at 17 different wavelengths, from X-ray to radio bands, starting 81 seconds after the burst and extendin…

Pre-ALMA observations of GRBs in the mm/submm range

A. de Ugarte Postigo, A. Lundgren, S. Martín +24

GRBs generate an afterglow emission that can be detected from radio to X-rays during days, or even weeks after the initial explosion. The peak of this emission crosses the mm/submm…

An unusual stellar death on Christmas Day

C. C. Thöne, A. de Ugarte Postigo, C. L. Fryer +31

Long Gamma-Ray Bursts (GRBs) are the most dramatic examples of massive stellar deaths, usually as- sociated with supernovae (Woosley et al. 2006). They release ultra-relativistic j…

Simultaneous polarization monitoring of supernovae SN2008D/XT080109 and SN2007uy: isolating geometry from dust

J. Gorosabel, A. de Ugarte Postigo, A. J. Castro-Tirado +16

The possible existence of a continuum encompassing the diversity of explosive stellar deaths,ranging from ordinary SNe to relativistic hypernovae associated with long duration GRBs…

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…

The host of GRB 060206: kinematics of a distant galaxy

Christina C. Thoene, Klaas Wiersema, Cedric Ledoux +13

We present early (starting 1.6h after the burst) WHT/ISIS optical spectroscopy of the afterglow of the gamma-ray burst GRB 060206 detecting a range of metal absorption lines and th…
