SN 1996cr: Confirmation of a Luminous Type IIn Supernova in the Circinus Galaxy
We have recently confirmed SN 1996cr as a late‐time type IIn supernova (SN) via VLT
spectroscopy and isolated its explosion date to∼ 1 yr using archival optical imaging. We
briefly touch upon here the wealth of optical, X‐ray, and radio archival observations
available for this enigmatic source. Due to its relative proximity (3.8±0.6 Mpc), SN 1996cr
ranks among the brightest X‐ray and radio SNe ever detected and, as such, may offer
powerful insights into the structure and composition of type IIn SNe. We also find that SN …
