Late-time HST and JWST Observations of GRB 221009A: Evidence for a Break in the Light Curve at 50 Days

Huei Sears, Ryan Chornock, Peter Blanchard +12

GRB 221009A is one of the brightest transients ever observed with the highest peak gamma-ray flux for a gamma-ray burst (GRB). A type Ic-BL supernova (SN), SN 2022xiw, was definiti…

Dinosaur in a Haystack : X-ray View of the Entrails of SN 2023ixf and the Radio Afterglow of Its Interaction with the Medium Spawned by the Progenitor Star (Paper 1)

A. J. Nayana, Raffaella Margutti, Eli Wiston +24

We present the results from our extensive hard-to-soft X-ray (NuSTAR, Swift-XRT, XMM-Newton, Chandra) and meter-to-mm wave radio (GMRT, VLA, NOEMA) monitoring campaign of the very…

PS1-11aop: Probing the Mass Loss History of a Luminous Interacting Supernova Prior to its Final Eruption with Multi-wavelength Observations

Adaeze L. Ibik, Maria R. Drout, Raffaela Margutti +14

Luminous interacting supernovae are a class of stellar explosions whose progenitors underwent vigorous mass loss in the years prior to core-collapse. While the mechanism by which t…

AT2023vto: An Exceptionally Luminous Helium Tidal Disruption Event from a Massive Star

Harsh Kumar, Edo Berger, Daichi Hiramatsu +10

We present optical/UV observations and the spectroscopic classification of the transient AT2023vto as a tidal disruption event (TDE) at z = 0.4846. The spectrum is dominated by a b…

The Long-lived Broadband Afterglow of Short Gamma-Ray Burst 231117A and the Growing Radio-Detected Short GRB Population

Genevieve Schroeder, Wen-fai Fong, Charles D. Kilpatrick +28

We present multiwavelength observations of the Swift short -ray burst GRB 231117A, localized to an underlying galaxy at redshift at a small projected offset ($\sim 2…

The Type I Superluminous Supernova Catalog I: Light Curve Properties, Models, and Catalog Description

Sebastian Gomez, Matt Nicholl, Edo Berger +25

We present the most comprehensive catalog to date of Type I Superluminous Supernovae (SLSNe), a class of stripped envelope supernovae (SNe) characterized by exceptionally high lumi…
