Core collapse supernovae and starbursts

Abstract

Core-collapse supernovae (CCSNe; Type Ib/c and Type II SNe) are the endproducts of massive stars (M ≥ 8 M⊙), and yield radio events whose brightness depends on the intensity of the interaction experienced by the supernova ejecta with the circumstellar presupernova wind material [1]. The fact that CCSNe are intrinsically radio supernovae-Albeit with a huge range of different radio powers-And hence unaffected by dust absorption, together with the high resolution and high sensitivity provided by current VLBI arrays, has been exploited to directly image the radio brightness structure of CCSNe in nearby (D
