A photometric redshift of for the \agile GRB 080514B
A. Rossi, A. de Ugarte Postigo, P. Ferrero +26
Aims: The AGILE gamma-ray burst GRB 080514B is the first burst with detected emission above 30 MeV and an optical afterglow. However, no spectroscopic redshift for this burst is kn…
Detection of GRB 060927 at z = 5.47: Implications for the Use of Gamma-Ray Bursts as Probes of the End of the Dark Ages
A. E. Ruiz-Velasco, H. Swan, E. Troja +54
We report on follow-up observations of the GRB 060927 using the ROTSE-IIIa telescope and a suite of larger aperture ground-based telescopes. An optical afterglow was detected 20 s…
A Deep Search with HST for Late Time Supernova Signatures in the Hosts of XRF 011030 and XRF 020427
Andrew Levan, Sandeep Patel, Chryssa Kouveliotou +16
X-ray Flashes (XRFs) are, like Gamma-Ray Bursts (GRBs), thought to signal the collapse of massive stars in distant galaxies. Many models posit that the isotropic equivalent energie…
GRB 020813: polarization in the case of a smooth optical decay
J. Gorosabel, E. Rol, S. Covino +35
We present the results of a VLT polarimetric monitoring campaign of the GRB 020813 optical afterglow carried out in three nights, from 0.88 to 4.20 days after the gamma-ray event.…
Optical and NIR Observations of the Afterglow of GRB 020813
S. Covino, D. Malesani, F. Tavecchio +28
We present optical and near-infrared (NIR) photometry of the bright afterglow of GRB 020813. Our data span from 3 hours to 4 days after the GRB event. A rather sharp achromatic bre…
Detection of the optical afterglow of GRB 000630: Implications for dark bursts
J. U. Fynbo, B. L. Jensen, J. Gorosabel +25
We present the discovery of the optical transient of the long-duration gamma-ray burst GRB000630. The optical transient was detected with the Nordic Optical Telescope 21.1 hours af…
