Discovery and Rapid Follow-up Observations of the Unusual Type II SN 2018ivc in NGC 1068
K. A. Bostroem, S. Valenti, D. J. Sand +44
We present the discovery and high-cadence follow-up observations of SN 2018ivc, an unusual Type II supernova that exploded in NGC 1068 (D=10.1 Mpc). The light curve of SN 2018ivc d…
SN 2017gmr: An energetic Type II-P supernova with asymmetries
Jennifer E. Andrews, D. J. Sand, S. Valenti +77
We present high-cadence ultraviolet (UV), optical, and near-infrared (NIR) data on the luminous Type II-P supernova SN 2017gmr from hours after discovery through the first 180 days…
The Type II-P Supernova 2017eaw: from explosion to the nebular phase
Tamás Szalai, József Vinkó, Réka Könyves-Tóth +36
The nearby SN 2017eaw is a Type II-P (``plateau') supernova showing early-time, moderate CSM interaction. We present a comprehensive study of this SN including the analysis of high…
Signatures of Circumstellar Interaction in the Type IIL Supernova ASASSN-15oz
K. Azalee Bostroem, Stefano Valenti, Assaf Horesh +27
Hydrogen-rich, core-collapse supernovae are typically divided into four classes: IIP, IIL, IIn, and IIb. In general, interaction with circumstellar material is only considered for…
