AT 2022csn: A Photometrically Peculiar Optical/UV Tidal Disruption Event in a Type II AGN

Yael Dgany, Iair Arcavi, Grisha Zeltyn +18

The emission mechanism and host galaxy preference of optical/UV tidal disruption events (TDEs) are still not entirely understood. We present observations of the TDE AT 2022csn, whi…

Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. I: Luminosity Function, Volumetric Rate

Kaustav K. Das, Mansi M. Kasliwal, Christoffer Fremling +51

We present the luminosity function and volumetric rate of a sample of Type IIP supernovae (SNe) from the Zwicky Transient Facility Census of the Local Universe survey (CLU). This i…

XSNAP: An X-ray Supernova Analysis Pipeline with Application to the Type II Supernova 2024ggi

Ferdinand, W. V. Jacobson-Galán, M. M. Kasliwal +1

X-ray observations of Type II supernovae (SNe II) probe the physics of supernova (SN) shocks and the mass-loss histories of their progenitor stars. We present multi-epoch, X-ray ob…

SN 2019vxm: A Shocking Coincidence between Fermi and TESS

Zachary G. Lane, Ryan Ridden-Harper, Sofia Rest +37

Shock breakout and, in some cases, jet-driven high-energy emission are increasingly recognized as key signatures of the earliest phases of core-collapse supernovae, especially in T…

A Faint Progenitor System for the Faint Supernova 2024vjm

Erez A. Zimmerman, Avishay Gal-Yam, Paul J. Groot +68

Type Ia Supernovae (SNe Ia) are well known for their role as standardizable cosmological candles. Their uniformity is credited to their single origin as thermonuclear explosions of…

A low mass, binary-stripped envelope for the Type IIb SN 2024abfo

S. de Wet, G. Leloudas, D. Buckley +3

Type IIb supernovae (SNe) are a transitional subclass of stripped-envelope SNe showing hydrogen lines in their spectra that gradually weaken and give way to helium lines reminiscen…
