Spectroscopy of the Host Galaxy of the Gamma – Ray Burst 980703
We present spectroscopic observations of the host galaxy of the γ-ray burst (GRB) 980703. Several emission and absorption features are detected, making the redshift, z = 0.966, completely unambiguous. This is only the third known redshift for a GRB host. The implied isotropic γ-ray energy release from the burst is in excess of 10 erg, for a reasonable choice of cosmological parameters. The spec...
متن کاملThe Host Galaxy of the Gamma – Ray Burst 971214
We report on Hubble Space Telescope (HST) observations of the host galaxy of GRB 971214, taken four months after the burst. The redshift of the proposed host galaxy at z = 3.418, combined with optical and radio observations of the burst afterglow, implies the extremely large isotropic energy release from the burst in γ-rays of Eγ ≈ 3 × 10 53 erg, some two orders of magnitude higher than the pre...
متن کاملGemini Spectroscopy of the Short - Hard Gamma - ray Burst GRB 130603 B Afterglow and Host Galaxy
We present early optical photometry and spectroscopy of the afterglow and host galaxy of the bright short-duration gamma-ray burst GRB 130603B discovered by the Swift satellite. Using our Target of Opportunity program on the Gemini South telescope, our prompt optical spectra reveal a strong trace from the afterglow superimposed on continuum and emission lines from the z = 0.3568±0.0005 host gal...
متن کاملThe afterglow and elliptical host galaxy of the short gamma-ray burst GRB 050724.
Despite a rich phenomenology, gamma-ray bursts (GRBs) are divided into two classes based on their duration and spectral hardness--the long-soft and the short-hard bursts. The discovery of afterglow emission from long GRBs was a watershed event, pinpointing their origin to star-forming galaxies, and hence the death of massive stars, and indicating an energy release of about 10(51) erg. While the...
