A characterization of ASAS-SN core-collapse supernova environments with VLT+MUSE: I. Sample selection, analysis of local environments, and correlations with light curve properties
Thallis Pessi, Jose L. Prieto, Joseph P. Anderson +17
The analysis of core-collapse supernova (CCSN) environments can provide important information on the life cycle of massive stars and constrain the progenitor properties of these po…
Supernova Rates and Luminosity Functions from ASAS-SN I: 2014--2017 Type Ia SNe and Their Subtypes
D. D. Desai, C. S. Kochanek, B. J. Shappee +9
We present the volumetric rates and luminosity functions (LFs) of Type Ia supernovae (SNe Ia) from the -band All-Sky Automated Survey for Supernovae (ASAS-SN) catalogues spannin…
Catching a nova X-ray/UV flash in the visible? Early spectroscopy of the extremely slow Nova Velorum 2022 (Gaia22alz)
E. Aydi, L. Chomiuk, J. Mikołajewska +22
We present early spectral observations of the very slow Galactic nova Gaia22alz, over its gradual rise to peak brightness that lasted 180 days. During the first 50 days, when the n…
ASAS-SN Sky Patrol V2.0
K. Hart, B. J. Shappee, D. Hey +13
The All-Sky Automated Survey for Supernovae (ASAS-SN) began observing in late-2011 and has been imaging the entire sky with nightly cadence since late 2017. A core goal of ASAS-SN…
Coronal Line Emitters are Tidal Disruption Events in Gas-Rich Environments
Jason T. Hinkle, Benjamin J. Shappee, Thomas W. -S. Holoien
Some galaxies show little to no sign of active galactic nucleus (AGN) activity, yet exhibit strong coronal emission lines (CLs) relative to common narrow emission lines. Many of th…
