Observations of gamma-ray bursts and a supernovae search at the robotic telescope MASTER
Abstract:We present here the results of observations made during 2005-2006 using the robotic telescope MASTER. The world's first observations of the optical emission of gamma-ray bursts GRB050824 and GRB060926 are shown. Our data combined with later observations give the law of brightness as proportional to t0.55±0.05 for GRB050824. We discovered an optical flare for GRB060926 at about 500-700 s. The power law spectral index (F∝ E-) is equal to =0.7±0.2. During the sky survey we have imaged more than 90% of the observable sky. Also we discovered three supernovae (SNs): SN2005bv of type Ia (this is the first SN discovered in Russia), SN2005ee (which is one of the brightest type II SN stars) and SN2006ak (type Ia).
