Scientific paper

SN1996cr is among the closest SNe to explode in the past 30 years, yet went undiscovered for many years. Due to its fortuitous location in the Circinus Galaxy at 3.7 Mpc, however, we have a wealth of serendipitous archival data available to piece together its early evolution. Like SN1987A, it appears to have exploded into a shell-like structure formed by the progenitor, sparking a unique temporal evolution. I will describe our current multi-wavelength constraints on SN1996cr, focusing on a new 485ks Chandra HETG spectrum, and discuss physical interpretations of the system with the aid of hydrodynamical simulations by our team.
