SiO Maser Line-width Diagnostics of AGB Stars and Red Supergiants: The RSG-adjacent Region in the FWZI--Luminosity Plane
Qiu-Yu Tao, Jun-ichi Nakashima, Yong Zhang +3
We investigate whether SiO maser line profiles can distinguish asymptotic giant branch (AGB) stars from red supergiants (RSGs) and identify unusual AGB-classified sources near the…
Follow-up of SN 2025wny III: Spectroscopic Time-delay Measurements of a Strongly Gravitationally Lensed Superluminous Supernova
Joel Johansson, Edvard Mörtsell, Ariel Goobar +30
We present spatially resolved spectra and infer the time-delays between the multiple images of the strongly gravitationally lensed superluminous supernova (SLSN) 2025wny at z=2.015…
Follow-up of SN 2025wny II: Superluminous Supernova Physics at Cosmic Noon
Maggie L. Li, Lin Yan, Anamaria Gkini +46
SN 2025wny is a gravitationally lensed, hydrogen-poor superluminous supernova (SLSN-I) at z = 2.015. To date, it is the most extensively observed high-redshift core-collapse SN and…
Mapping the Spatial Distribution of Fast Radio Bursts within their Host Galaxies
Alexa C. Gordon, Wen-fai Fong, Adam T. Deller +23
We present deep optical and near-infrared observations of the host galaxies of 34 fast radio bursts (FRBs) detected by the Commensal Real-time ASKAP Fast Transient (CRAFT) survey o…
The La Silla Schmidt Southern Survey
Adam A. Miller, Natasha S. Abrams, Greg Aldering +75
We present the La Silla Schmidt Southern Survey (LS4), a new wide-field, time-domain survey to be conducted with the 1 m ESO Schmidt telescope. The 268 megapixel LS4 camera mosaics…
A Luminous Red Optical Flare and Hard X-ray Emission in the Tidal Disruption Event AT2024kmq
Anna Y. Q. Ho, Yuhan Yao, Tatsuya Matsumoto +30
We present the optical discovery and multiwavelength follow-up observations of AT2024kmq, a likely tidal disruption event (TDE) associated with a supermassive ($M_{\rm BH}\sim 10^{…
Repeating Partial Tidal Encounters of Sun-like Stars Leading to their Complete Disruption
Chang Liu, Ricardo Yarza, Enrico Ramirez-Ruiz
Stars grazing supermassive black holes on bound orbits may produce periodic flares over many passages, known as repeating partial tidal disruption events (TDEs). Here, we present 3…
SN 2023zaw: an ultra-stripped, nickel-poor supernova from a low-mass progenitor
Kaustav K. Das, Christoffer Fremling, Mansi M. Kasliwal +34
We present SN 2023zaw a sub-luminous ( mag) and rapidly-evolving supernova ( days), with the lowest nickel mass (…
A 12.4 day periodicity in a close binary system after a supernova
Ping Chen, Avishay Gal-Yam, Jesper Sollerman +37
Neutron stars and stellar-mass black holes are the remnants of massive star explosions. Most massive stars reside in close binary systems, and the interplay between the companion s…
Gaia22dkvLb: A Microlensing Planet Potentially Accessible to Radial-Velocity Characterization
Zexuan Wu, Subo Dong, Tuan Yi +50
We report discovering an exoplanet from following up a microlensing event alerted by Gaia. The event Gaia22dkv is toward a disk source rather than the traditional bulge microlensin…
Tidal disruption events from eccentric orbits and lessons learned from the noteworthy ASASSN-14ko
Chang Liu, Brenna Mockler, Enrico Ramirez-Ruiz +5
Stars grazing supermassive black holes (SMBHs) on bound orbits may survive tidal disruption, causing periodic flares. Inspired by the recent discovery of the periodic nuclear trans…
Impact of an Active Sgr A* on the Synthesis of Water and Organic Molecules Throughout the Milky Way
Chang Liu, Xian Chen, Fujun Du
Sgr A*, the supermassive black hole (SMBH) in our Galaxy, is dormant today, but it should have gone through multiple gas-accretion episodes in the past billions of years to grow to…
