Multiple Flares in the Changing-Look AGN NGC 5273
J. M. M. Neustadt, J. T. Hinkle, C. S. Kochanek +15
NGC 5273 is a known optical and X-ray variable AGN. We analyze new and archival IR, optical, UV, and X-ray data in order to characterize its long-term variability from 2000 to 2022…
The Value-Added Catalog of ASAS-SN Eclipsing Binaries II: Properties of Extra-Physics Systems
D. M. Rowan, T. Jayasinghe, K. Z. Stanek +6
Detached eclipsing binaries are the primary tool used to measure precise masses and radii of stars. In our previous paper estimating the parameters of more than 30,000 detached ecl…
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…
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…
The Galactic Nova Rate: Estimates from the ASAS-SN and Gaia Surveys
A. Kawash, L. Chomiuk, J. Strader +13
We present the first estimate of the Galactic nova rate based on optical transient surveys covering the entire sky. Using data from the All-Sky Automated Survey for Supernovae (ASA…
