The fraction of periodic SN Ib/c light curves
Asaf Horowicz, Eran O. Ofek, Avishay Gal-Yam
Periodic luminosity modulations have been recently identified for the stripped-envelope supernovae SN 2022jli and SN 2022esa, motivating a systematic search for a similar behavior…
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…
The Large Array Survey Telescope-Pipeline. II. Image Subtraction and Transient Detection
R. Konno, E. O. Ofek, A. Krassilchtchikov +16
Context. The Large Array Survey Telescope (LAST) is a wide-field visual-band survey designed to explore the variable and transient sky with high cadence. Its raw data stream is aut…
The Type IIn SN 2025cbj coincidence with the high-energy neutrino IceCube-250421A
S. Garrappa, E. A. Zimmerman, T. Wasserman +14
Context. The origin of the astrophysical high-energy neutrino flux remains uncertain. Core-collapse supernovae with strong CSM interaction (Type IIn) are compelling candidates for…
Characterizing Supernova Host Galaxies with FrankenBlast: A Scalable Tool for Transient Host Galaxy Association, Photometry, and Stellar Population Modeling
Anya E. Nugent, V. Ashley Villar, Alex Gagliano +5
We present FrankenBlast, a customized and improved version of the Blast web application. FrankenBlast associates transients to their host galaxies, performs host photometry, and ru…
The Host Galaxies of Fast Radio Bursts Track a Combination of Stellar Mass and Star Formation, Similar to Type Ia Supernovae
Asaf Horowicz, Ben Margalit
We develop a new statistical framework for studying the host galaxies of astrophysical sources that accounts for both redshift evolution and the multi-variate nature of host-galaxy…
