The Young Supernova Experiment: Survey Goals, Overview, and Operations

D. O. Jones, R. J. Foley, G. Narayan +68

Time domain science has undergone a revolution over the past decade, with tens of thousands of new supernovae (SNe) discovered each year. However, several observational domains, in…

Radiative Emission Mechanisms of Tidal Disruption Events

Nathaniel Roth, Elena M. Rossi, Julian H. Krolik +3

We describe how the various outcomes of stellar tidal disruption give rise to observable radiation. We separately consider the cases where gas circularizes rapidly into an accretio…

An Energy Inventory of Tidal Disruption Events

Brenna Mockler, Enrico Ramirez-Ruiz

Tidal disruption events (TDEs) offer a unique opportunity to study a single super-massive black hole (SMBH) under feeding conditions that change over timescales of days or months.…

The Rise and Fall of ASASSN-18pg: Following a TDE from Early To Late Times

Thomas W. -S. Holoien, Katie Auchettl, Michael A. Tucker +29

We present nearly 500 days of observations of the tidal disruption event ASASSN-18pg, spanning from 54 days before peak light to 441 days after peak light. Our dataset includes X-r…

Double-Peaked Balmer Emission Indicating Prompt Accretion Disk Formation in an X-Ray Faint Tidal Disruption Event

Tiara Hung, Ryan J. Foley, Enrico Ramirez-Ruiz +13

We present the multi-wavelength analysis of the tidal disruption event (TDE) AT~2018hyz (ASASSN-18zj). From follow-up optical spectroscopy, we detect the first unambiguous case of…

The spectral evolution of AT 2018dyb and the presence of metal lines in tidal disruption events

Giorgos Leloudas, Lixin Dai, Iair Arcavi +29

We present light curves and spectra of the tidal disruption event (TDE) ASASSN-18pg / AT 2018dyb spanning a period of one year. The event shows a plethora of strong emission lines,…
