Nebular Spectra of the Extremely Metal-Poor SN II 2023ufx Over a Year After Explosion: A Massive Progenitor and Unique Circumstellar Environment

Evan Jennerjahn, Michael A. Tucker, Christopher S. Kochanek +3

We present new observations of the metal-poor ( ) Type II supernova 2023ufx and its host galaxy. The deep nebular spectrum, obtained roughly a year after explos…

ATLAS22kjn (AT 2022fpx): A Coronal Line Emitter with an Early Light Curve Bump and Mid-Infrared Dust Echo

Athena C. Engholm, Jason T. Hinkle, Benjamin J. Shappee +14

We present an analysis of ATLAS22kjn (AT 2022fpx), whose high-ionisation coronal lines (CLs) and pre-peak light curve bump provide distinctive opportunities to investigate the phys…

AT2021yky: A Fast-Rising Optical Transient with Evolving Broad Hydrogen Emission Consistent with an Ambiguous Nuclear Transient

Paarmita Pandey, Jason T. Hinkle, Christopher Kochanek +14

Nuclear transients are powerful probes of supermassive black hole properties, offering insight into black hole mass, accretion physics, and the structure of galactic nuclei. Among…

A Disappearing Act: Constraints From "Missing" Flares of Repeating Partial TDE Candidates

Jason T. Hinkle, Chang Liu, Adam A. Miller +6

Recurrent tidal disruption events (rTDEs) are sources that exhibit multiple TDE-like flares; many are likely powered by the recurring partial disruption of a bound star, in a repea…

AGN STORM 2. XII. Ground-Based Optical Photometry and Lag Measurements of Mrk 817

John W. Montano, Aaron J. Barth, Keith Horne +40

We present the ground-based imaging campaign and light curves of Markarian 817 as part of the multiwavelength monitoring program AGN STORM\,2. Observations were carried out over 1.…

The neighboring stars of N6946-BH1 and the observational characteristics of failed supernovae

R. Forés-Toribio, C. S. Kochanek

Stellar collapse models predict that some stars more massive than 15 may collapse directly to a black hole, sometimes with a weak optical transient, a phenomenon kno…
