Extreme Stellar Death and Galaxy Feedback at z = 2: A Rest-frame Ultraviolet Characterization of the Strongly Lensed Superluminous Supernova 2025wny

Willem B. Hoogendam, David O. Jones, Christopher J. Storfer +26

We present photometric and spectroscopic follow-up observations of the strongly-lensed H-poor superluminous supernova (SLSN) 2025wny at . We use integral-field Keck-II/…

A Proliferated Space Architecture for Time-Domain Astrophysics

Daniel Kocevski, Eric Burns, Thomas Barclay +58

Time-Domain and Multi-Messenger Astrophysics (TDAMM) is entering a discovery-rich but follow-up-limited era, creating an urgent need for responsive, multiwavelength space-based cap…

JWST and Keck observations of the off-nuclear tidal disruption event TDE 2025abcr: An evolving reprocessing layer

Kishore C. Patra, Emily R. Liepold, Nicholas Earl +14

Off-nuclear tidal disruption events (TDEs) provide a rare probe of massive black holes (MBHs) outside galactic nuclei. Only a handful are known, including five X-ray-selected candi…

Radial Velocity Evidence for a Post-Mass-Transfer Massive Binary System NaSt1

Kittipong Wangnok, Samaporn Tinyanont, Ryan M. Lau +11

We present multi-epoch high-resolution optical spectroscopy () of the emission-line object NaSt1 to test its proposed binary nature, along with long-term multiba…

GRB 230307A Formed No Dust or Was Not a Binary Neutron Star Merger

Prasiddha Arunachalam, Phillip Macias, Ryan. J. Foley

We present a new analysis of the JWST infrared spectra of GRB 230307A (AT 2023vfi), a long gamma-ray burst (GRB) with an infrared excess and spectral lines suggestive of significan…

JWST and Keck Observations of the Off-Nuclear TDE AT 2024tvd: A Massive Nuclear Star Cluster and Minor-Merger Origin for its Black Hole

Kishore C. Patra, Ryan J. Foley, Nicholas Earl +10

We present JWST/NIRSpec and NIRCam observations of the first optically selected off-nuclear tidal disruption event (TDE), AT 2024tvd, along with Keck/KCWI integral field unit spect…
