D. %D 2017 %K grb host muse %T The MUSE view of the host galaxy of GRB 100316D %U http://arxiv.org/abs/1704.05509 %X The peculiar nature of the host galaxy of the low-luminosity GRB 100316D has baffled the astronomers since its first detection. The low distance, $z=0.0591$, of GRB 100316D and its association with SN 2010bh represent two important motivations for studying this host galaxy and the GRB's immediate environment with the high spatial resolution provided by the VLT/MUSE. Its large field-of-view allows us to create 2D maps of gas metallicity, ionization level and the star-formation rate distribution maps. Based on these, we derive that the GRB exploded in the most active star-forming region of the galaxy, characterized by a low metallicity and a young stellar population. We conclude that the host is a late-type dwarf galaxy characterized by the presence of multiple star-forming regions and an extended central region with on-going shock interactions. The galaxy likely experienced a relatively recent gravitational encounter, that also triggered an intense burst of star-formation 5-15 Myr ago, generating a massive stellar population (including stars with masses up to 20 -- 40 $M_ødot$) at the GRB site.
