Dark Gamma-Ray Bursts and their Host Galaxies
Abstract
Despite the rapid GRB follow-up with robotic telescopes, 20-40% of long duration GRBs show a lack or even total absence of the optical afterglow. These events are called optically dark bursts. Only observations of X-ray afterglow and host galaxy of those dark bursts allow us to study the parameters of dark GRB sources and their environment and to determine the nature of the burst darkness. We review recent observations and present statistical studies of optically dark gamma-ray bursts and their host galaxies. Also we discuss their properties in comparison ordinary bright bursts.
