A Multiwavelength Study of the Massive Colliding Wind Binary WR 20a: A Possible Progenitor for Fast-Spinning LIGO Binary Black Hole Mergers
Grace M. Olivier, Laura A. Lopez, Katie Auchettl +7
WR 20a is the most massive close-in binary known in our Galaxy. It is composed of two 80 M Wolf-Rayet stars with a short period of 3.7 days in the open cl…
The ASAS-SN Bright Supernova Catalog -- V. 2018-2020
K. D. Neumann, T. W. -S. Holoien, C. S. Kochanek +55
We catalog the 443 bright supernovae discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) in along with the 519 supernovae recovered by ASAS-SN and 516 a…
Revealing AGNs Through TESS Variability
Helena P. Treiber, Jason T. Hinkle, Michael M. Fausnaugh +7
We used Transiting Exoplanet Survey Satellite (TESS) data to identify 29 candidate active galactic nuclei (AGNs) through their optical variability. The high-cadence, high-precision…
Observations of the luminous red nova AT 2021biy in the nearby galaxy NGC 4631
Y. -Z. Cai, A. Pastorello, M. Fraser +73
We present an observational study of the luminous red nova (LRN) AT\,2021biy in the nearby galaxy NGC\,4631. The field of the object was routinely imaged during the pre-eruptive st…
Examining the Properties of Low-Luminosity Hosts of Type Ia Supernovae from ASAS-SN
Thomas W. -S. Holoien, Vera L. Berger, Jason T. Hinkle +14
We present a spectroscopic analysis of 44 low-luminosity host galaxies of Type Ia supernovae (SNe Ia) detected by the All-Sky Automated Survey for Supernovae (ASAS-SN), using the e…
Chandra, HST/STIS, NICER, Swift, and TESS Detail the Flare Evolution of the Repeating Nuclear Transient ASASSN-14ko
Anna V. Payne, Katie Auchettl, Benjamin J. Shappee +9
ASASSN-14ko is a nuclear transient at the center of the AGN ESO 253-G003 that undergoes periodic flares. Optical flares were first observed in 2014 by the All-Sky Automated Survey…
