SN Environments in LEGUS
Abstract
From the LEGUS multi-band data we can analyze the stellar environments of recent supernovae (SNe), attempt to recover emission from the aging SNe, and search for light echoes around them. We can attempt to constrain the properties of the SN progenitor, based on age estimates for stellar populations in the immediate SN environments. The sites of 15 SNe of various types can be isolated in these images. I will briefly provide a summary of what we have learned about these SNe from their LEGUS environments. A few of these environments have been analyzed and published by other teams. In addition, two SNe occurred shortly after observations were made of two of the galaxies in our sample, NGC 4258 and NGC 1566. I will talk about the inferences we can make regarding the progenitors of these two core-collapse events. In general, the LEGUS dataset will be a valuable resource for identifying the progenitors of future SNe.
