Luminous Radio Emission from the Superluminous Supernova 2017ens at 3.3 years after explosion

Raffaella Margutti, J. S. Bright, D. J. Matthews +17

We present the results from a multi-year radio campaign of the superluminous supernova (SLSN) 2017ens, which yielded the earliest radio detection of a SLSN to date at the age of $\…

SN2023ixf in Messier 101: A Variable Red Supergiant as the Progenitor Candidate to a Type II Supernova

Charles D. Kilpatrick, Ryan J. Foley, Wynn V. Jacobson-Galán +15

We present pre-explosion optical and infrared (IR) imaging at the site of the type II supernova (SN II) 2023ixf in Messier 101 at 6.9 Mpc. We astrometrically registered a ground-ba…

SN 2023ixf in Messier 101: Photo-ionization of Dense, Close-in Circumstellar Material in a Nearby Type II Supernova

W. V. Jacobson-Galan, L. Dessart, R. Margutti +65

We present UV/optical observations and models of supernova (SN) 2023ixf, a type II SN located in Messier 101 at 6.9 Mpc. Early-time ("flash") spectroscopy of SN 2023ixf, obtained p…

Unprecedented X-ray Emission from the Fast Blue Optical Transient AT2022tsd

D. J. Matthews, R. Margutti, B. D. Metzger +8

We present the X-ray monitoring campaign of AT2022tsd in the time range d rest-frame since discovery. With an initial 0.3-10 keV X-ray luminosity of $L_x \ap…

Scary Barbie: An Extremely Energetic, Long-Duration Tidal Disruption Event Candidate Without a Detected Host Galaxy at z = 0.995

Bhagya M. Subrayan, Dan Milisavljevic, Ryan Chornock +19

We report multi-wavelength observations and characterization of the ultraluminous transient AT 2021lwx (ZTF20abrbeie; aka ``Barbie'') identified in the alert stream of the Zwicky T…
