Probing the Circumstellar Environment of the Highly Luminous Type IIn Supernova ASASSN-14il

Probing the Circumstellar Environment of the Highly Luminous Type IIn Supernova ASASSN-14il

We present long-term photometric and spectroscopic studies of circumstellar material (CSM)–ejecta interacting supernova (SN) ASASSN-14il in the galaxy PGC 3093694. The SN reaches a peak r -band magnitude of ∼−20.3 ± 0.2 mag, rivaling SN 2006tf and SN 2010jl. The multiband and the pseudo-bolometric l...
