A Carbon/Oxygen-dominated Atmosphere Days After Explosion for the "Super-Chandrasekhar" Type Ia SN 2020esm
Georgios Dimitriadis, Ryan J. Foley, Nikki Arendse +18
Seeing pristine material from the donor star in a Type Ia supernova (SN Ia) explosion can reveal the nature of the binary system. In this paper, we present photometric and spectros…
SN 2020kyg and the rates of faint Iax Supernovae from ATLAS
Shubham Srivastav, S. J. Smartt, M. E. Huber +17
We present multi-wavelength follow-up observations of the ATLAS discovered faint Iax supernova SN 2020kyg that peaked at an absolute magnitude of , makin…
Is the high-energy neutrino event IceCube-200530A associated with a hydrogen-rich superluminous supernova?
Tetyana Pitik, Irene Tamborra, Charlotte R. Angus +1
The Zwicky Transient Facility (ZTF) follow-up campaign of alerts released by the IceCube Neutrino Observatory has led to the likely identification of the transient AT2019fdr as the…
Evidence for the preferential disruption of moderately massive stars by supermassive black holes
Brenna Mockler, Angela A. Twum, Katie Auchettl +4
Tidal disruption events (TDEs) provide a unique opportunity to probe the stellar populations around supermassive black holes (SMBHs). By combining light curve modeling with spectra…
Final Moments I: Precursor Emission, Envelope Inflation, and Enhanced Mass loss Preceding the Luminous Type II Supernova 2020tlf
Wynn Jacobson-Galán, Luc Dessart, David Jones +33
We present panchromatic observations and modeling of supernova (SN) 2020tlf, the first normal type II-P/L SN with confirmed precursor emission, as detected by the Young Supernova E…
Investigating the Nature of the Luminous Ambiguous Nuclear Transient ASASSN-17jz
Thomas W. -S. Holoien, Jack M. M. Neustadt, Patrick J. Vallely +31
We present observations of the extremely luminous but ambiguous nuclear transient (ANT) ASASSN-17jz, spanning roughly 1200 days of the object's evolution. ASASSN-17jz was discovere…
