Flash ionization signatures in the type Ibn supernova SN 2019uo
Anjasha Gangopadhyay, Kuntal Misra, Daichi Hiramatsu +26
We present photometric and spectroscopic observations of the type Ibn supernova (SN) 2019uo, the second ever SN Ibn with flash ionization (He II, C III, N III) features in its earl…
Low frequency view of GRB 190114C reveals time varying shock micro-physics
K. Misra, L. Resmi, D. A. Kann +25
We present radio and optical afterglow observations of the TeV-bright long Gamma Ray Burst (GRB) 190114C at a redshift of , which was detected by the MAGIC telescope. Our…
SN 2015an: a normal luminosity type II supernova with low expansion velocity at early phases
Raya Dastidar, Kuntal Misra, Stefano Valenti +10
We present the photometry and spectroscopy of SN 2015an, a Type II Supernova (SN) in IC 2367. The recombination phase of the SN lasts up to 120 d, with a decline rate of 1.24…
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…
SN 2016B a.k.a ASASSN-16ab: a transitional type II supernova
Raya Dastidar, Kuntal Misra, Mridweeka Singh +12
We present photometry, polarimetry and spectroscopy of the Type II supernova ASASSN-16ab/SN 2016B in PGC 037392. The photometric and spectroscopic follow-up commenced about two wee…
