The host galaxies of gamma-ray bursts. I. Interstellar medium properties of ten nearby long-duration gamma-ray burst hosts

Levesque, E. M.; Berger, Edo; Kewley, Lisa; Bagley, Megan M.


We present the first observations from a large-scale survey of nearby (z < 1) long-duration gamma-ray burst (LGRB) host galaxies, which consist of eight rest-frame optical spectra obtained at Keck and Magellan. Along with two host galaxy observations from the literature, we use optical emission-line diagnostics to determine metallicities, ionization parameters, young stellar population ages, and star formation rates. We compare the LGRB host environments to a variety of local and...[Show more]
