Constraints on the Star-Forming Galaxy Luminosity Function From Imaging of an Unbiased and Complete Sample of Long Gamma-ray Burst Host Galaxies
Huei Sears, Ryan Chornock, Jay Strader +4
We present rest-frame UV \textit{Hubble Space Telescope} imaging of the largest and most complete sample of 23 long duration gamma-ray burst (GRB) host galaxies between redshifts 4…
JWST Observations of the Extraordinary GRB 221009A Reveal an Ordinary Supernova Without Signs of -Process Enrichment in a Low-Metallicity Galaxy
Peter K. Blanchard, V. Ashley Villar, Ryan Chornock +18
Identifying the astrophysical sites of the -process, one of the primary mechanisms by which heavy elements are formed, is a key goal of modern astrophysics. The discovery of the…
A Radio Flare in the Long-Lived Afterglow of the Distant Short GRB 210726A: Energy Injection or a Reverse Shock from Shell Collisions?
Genevieve Schroeder, Lauren Rhodes, Tanmoy Laskar +32
We present the discovery of the radio afterglow of the short -ray burst (GRB) 210726A, localized to a galaxy at a photometric redshift of . While radio observations c…
SN 2022joj: A Peculiar Type Ia Supernova Possibly Driven by an Asymmetric Helium-shell Double Detonation
Chang Liu, Adam A. Miller, Samuel J. Boos +28
We present observations of SN 2022joj, a peculiar Type Ia supernova (SN Ia) discovered by the Zwicky Transient Facility (ZTF). SN 2022joj exhibits an unusually red $g_\mathrm{ZTF}-…
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…
The Demographics, Stellar Populations, and Star Formation Histories of Fast Radio Burst Host Galaxies: Implications for the Progenitors
Alexa C. Gordon, Wen-fai Fong, Charles D. Kilpatrick +26
We present a comprehensive catalog of observations and stellar population properties for 23 highly secure host galaxies of fast radio bursts (FRBs). Our sample comprises six repeat…
