SN2023ixf in Messier 101: the twilight years of the progenitor as seen by Pan-STARRS
Conor L. Ransome, V. Ashley Villar, Anna Tartaglia +28
The nearby type II supernova, SN2023ixf in M101 exhibits signatures of early-time interaction with circumstellar material in the first week post-explosion. This material may be the…
SN 2022oqm: A Bright and Multi-peaked Calcium-rich Transient
S. Karthik Yadavalli, V. Ashley Villar, Luca Izzo +60
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multi-peaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kp…
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 $\…
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…
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…
