Název v původním jazyce

A quiescent galaxy at the position of the long GRB 050219A

Popis výsledku v původním jazyce

Context. Long-duration gamma-ray bursts (LGRBs) are produced by the collapse of very massive stars. Because of the short life time of their progenitors, LGRBs pinpoint star-forming galaxies. Recent studies demonstrate that LGRBs populate all types of star-forming galaxies from sub-luminous, blue compact dwarfs to luminous infrared galaxies. Aims: We present here a multi-band search for the host galaxy of the long dark GRB 050219A within the enhanced Swift/XRT error circle. We aim to characterise the properties of its host galaxy and compare them with those of other LGRB host galaxies. Methods: We used spectroscopic observations acquired with VLT/X-Shooter to determine the redshift and star-formation rate of the most probable host galaxy identified on the basis of a chance probability criterion. We compared the results with the optical and infrared spectral energy distribution obtained with Swift/UVOT, the seven-channel imager GROND at the 2.2-m telescope on La Silla and the Herschel Sp
