The Maser-Starburst connection in NGC253

Abstract

NGC253 is one of the closest starburst galaxies to the Milky Way and as such it has been studied in detail across the electromagnetic spectrum. Recent observations have detected the first extragalactic class I methanol masers at 36 and 44 GHz and the first extragalactic HC${}_3$N (cyanoacetylene) masers in this source. Here we discuss the location of the masers with respect to key morphological features within NGC253 and the association between the masers and the ongoing starburst.
