Discovery and Follow-up of ASASSN-19dj: An X-ray and UV Luminous TDE in an Extreme Post-Starburst Galaxy
Jason T. Hinkle, T. W. -S. Holoien, K. Auchettl +28
We present observations of ASASSN-19dj, a nearby tidal disruption event (TDE) discovered in the post-starburst galaxy KUG 0810+227 by the All-Sky Automated Survey for Supernovae (A…
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…
A Possible Distance Bias for Type Ia Supernovae with Different Ejecta Velocities
M. R. Siebert, R. J. Foley, D. O. Jones +1
After correcting for their light-curve shape and color, Type Ia supernovae (SNe Ia) are precise cosmological distance indicators. However, there remains a non-zero intrinsic scatte…
DES16C3cje: A low-luminosity, long-lived supernova
C. P. Gutiérrez, M. Sullivan, L. Martinez +89
We present DES16C3cje, a low-luminosity, long-lived type II supernova (SN II) at redshift 0.0618, detected by the Dark Energy Survey (DES). DES16C3cje is a unique SN. The spectra a…
