Supernova 2013fc in a circumnuclear ring of a luminous infrared galaxy: the big brother of SN 1998S
T. Kangas, S. Mattila, E. Kankare +30
We present photometric and spectroscopic observations of SN 2013fc, a bright type II supernova (SN) in a circumnuclear star-forming ring in the luminous infrared galaxy ESO 154-G01…
On the triple peaks of SNHunt248 in NGC 5806
E. Kankare, R. Kotak, A. Pastorello +19
We present our findings on a supernova (SN) impostor, SNHunt248, based on optical and near-IR data spanning 15 yrs before discovery, to 1 yr post-discovery. The light c…
LSQ14bdq: A Type Ic super-luminous supernova with a double-peaked light curve
M. Nicholl, S. J. Smartt, A. Jerkstrand +28
We present data for LSQ14bdq, a hydrogen-poor super-luminous supernova (SLSN) discovered by the La Silla QUEST survey and classified by the Public ESO Spectroscopic Survey of Trans…
SN 2011A: an low-luminosity interacting transient, with a double plateau and strong sodium absorption
T. de Jaeger, J. P. Anderson, G. Pignata +16
We present optical photometry and spectroscopy of the optical transient SN 2011A. Our data spans 140 days after discovery including photometry and 11 epochs of opt…
On the diversity of super-luminous supernovae: ejected mass as the dominant factor
M. Nicholl, S. J. Smartt, A. Jerkstrand +37
We assemble a sample of 24 hydrogen-poor super-luminous supernovae (SLSNe). Parameterizing the light curve shape through rise and decline timescales shows that the two are highly c…
SN 2009ip at late times - an interacting transient at +2 years
Morgan Fraser, Rubina Kotak, Andrea Pastorello +31
We present photometric and spectroscopic observations of the interacting transient SN 2009ip taken during the 2013 and 2014 observing seasons. We characterise the photometric evolu…
