The low-extinction afterglow in the solar-metallicity host galaxy of gamma-ray burst 110918A

Original language description

The subject of this work is the very energetic GRB 110918A (E-gamma,E-iso = 1.9 x 10(54) erg), for which we measure a redshift of z = 0.984. GRB 110918A gave rise to a luminous afterglow with an intrinsic spectral slope of beta = 0.70, which probed a sight-line with little extinction (A(V)(GRB) = 0.16 mag) and soft X-ray absorption (N-H,N-X = (1.6 +/- 0.5) x 10(21) cm(-2)) typical of the established distributions of afterglow properties. However, photometric and spectroscopic follow-up observations of the galaxy hosting GRB 110918A, including optical/near-infrared photometry with the Gamma-Ray burst Optical Near-infrared Detector and spectroscopy with the Very Large Telescope/X-shooter, reveal an all but average GRB host in comparison to the z similarto 1 galaxies selected through similar afterglows to date. It has a large spatial extent with a half-light radius of R-1/2 similar to 10 kpc, the highest stellar mass for z < 1.9 (log(M-*/M-circle dot) = 10.68 +/- 0.16), and an H alpha-ba
