Metallicity in the Grb 100316d/sn 2010bh Host Complex. The Astrophysical Journal 739, no. 1: 23. doi:10.1088/0004-637x/739/1/23.0004-637Xhttp://nrs.harvard.edu/urn-3:HUL.InstRepos:30410835The recent long-duration GRB 100316D, associated with supernova SN 2010bh and detected by Swift, is one of the nearest GRB-SNe ever observed (z = 0.059). This provides us with a unique opportunity to study the explosion environment on ∼ kpc scale in relation to the host galaxy complex. Here we present spatially-resolved spectrophotometry of the host galaxy, focusing on both the explosion site and the brightest star-forming regions. Using these data, we extract the spatial profiles of the relevant emission features (Hα, Hβ, [OIII]λ5007, and [NII]λ6584), and use these profiles to examine variations in metallicity and star formation rate as a function of position in the host galaxy. We conclude that GRB 100316D/SN2010bh occurred in a low-metallicity host galaxy, and that the GRB-SN explosion site corresponds to the region with the lowest metallicity and highest star formation rate sampled by our observations.en-USJournal Article2017-02-2210.1088/0004-637x/739/1/23
