TL;DR: In this article, the putative progenitor of the Type IIb SN 2011dh was detected using archival pre-explosion Hubble Space Telescope images, which correspond to a single star at the end of core C-burning with an initial mass of 13 ± 3 M ☉.

TL;DR: In this paper, the authors present observations of SN 2015bn, a Type I superluminous supernova (SLSN) at redshift z = 0.1136, and derive physical properties including the bolometric luminosity and non-monotonic temperature and radial evolution.
