To TDE or not to TDE: The luminous transient ASASSN-18jd with TDE-like and AGN-like qualities
J. M. M. Neustadt, T. W. -S. Holoien, C. S. Kochanek +26
We present the discovery of ASASSN-18jd (AT 2018bcb), a luminous optical/UV/X-ray transient located in the nucleus of the galaxy 2MASX J22434289--1659083 at . Over the ye…
SN 2016gsd: An unusually luminous and linear type II supernova with high velocities
T. M. Reynolds, M. Fraser, S. Mattila +27
We present observations of the unusually luminous Type II supernova (SN) 2016gsd. With a peak absolute magnitude of V = 19.95 0.08, this object is one of the brightest Typ…
Variable H Emission in the Nebular Spectra of the Low-Luminosity Type Ia SN2018cqj/ATLAS18qtd
Jose L. Prieto, Ping Chen, Subo Dong +6
We present optical photometry and spectroscopy of the Type Ia supernova SN2018cqj/ATLAS18qtd. The supernova exploded in an isolated region at ~kpc from the S0 galaxy IC~55…
SN 2016coi (ASASSN-16fp): an energetic H-stripped core-collapse supernova from a massive stellar progenitor with large mass loss
G. Terreran, R. Margutti, D. Bersier +25
We present comprehensive observations and analysis of the energetic H-stripped SN 2016coi (a.k.a. ASASSN-16fp), spanning the -ray through optical and radio wavelengths, acquired…
The Most Rapidly Declining Type I Supernova 2019bkc/ATLAS19dqr
Ping Chen, Subo Dong, M. D. Stritzinger +21
We report observations of the hydrogen-deficient supernova (SN) 2019bkc/ATLAS19dqr. With B- and r-band decline between peak and 10 days post peak of Delta m_10(B)=5.24+/-0.07 mag a…
ASASSN-15pz: Revealing Significant Photometric Diversity among 2009dc-like, Peculiar SNe Ia
Ping Chen, Subo Dong, Boaz Katz +17
We report comprehensive multi-wavelength observations of a peculiar Type Ia-like supernova ("SN Ia-pec") ASASSN-15pz. ASASSN-15pz is a spectroscopic "twin" of SN 2009dc, a so-calle…
ASASSN-18tb: A Most Unusual Type Ia Supernova Observed by TESS and SALT
P. J. Vallely, M. Fausnaugh, S. W. Jha +16
We present photometric and spectroscopic observations of the unusual Type Ia supernova ASASSN-18tb, including a series of SALT spectra obtained over the course of nearly six months…
H- emission in the nebular spectrum of the Type Ia supernova ASASSN-18tb
Juna A. Kollmeier, Ping Chen, Subo Dong +6
As part of the 100IAS survey, a program aimed to obtain nebular-phase spectra for a volume-limited and homogeneous sample of Type Ia supernovae (SNe Ia), we observed ASASSN-18tb (S…
