A Fast Radio Burst in a Compact Galaxy Group at ~1
Alexa C. Gordon, Wen-fai Fong, Sunil Simha +14
FRB 20220610A is a high-redshift Fast Radio Burst (FRB) that has not been observed to repeat. Here, we present rest-frame UV and optical observati…
Limits on Optical Counterparts to the Repeating FRB 20180916B from High-speed Imaging with Gemini-N/'Alopeke
Charles D. Kilpatrick, Nicolas Tejos, J. Xavier Prochaska +6
We report on contemporaneous optical observations at ~10 ms timescales from the fast radio burst (FRB) 20180916B of two repeat bursts (FRB 20201023, FRB 20220908) taken with the 'A…
Strong Carbon Features and a Red Early Color in the Underluminous Type Ia SN 2022xkq
Jeniveve Pearson, David J. Sand, Peter Lundqvist +85
We present optical, infrared, ultraviolet, and radio observations of SN 2022xkq, an underluminous fast-declining type Ia supernova (SN Ia) in NGC 1784 ( Mpc),…
SpectAcLE: An Improved Method for Modeling Light Echo Spectra
Roee Partoush, Armin Rest, Jacob E. Jencson +17
Light echoes give us a unique perspective on the nature of supernovae and non-terminal stellar explosions. Spectroscopy of light echoes can reveal details on the kinematics of the…
Keck Infrared Transient Survey I: Survey Description and Data Release 1
S. Tinyanont, R. J. Foley, K. Taggart +35
We present the Keck Infrared Transient Survey (KITS), a NASA Key Strategic Mission Support program to obtain near-infrared (NIR) spectra of astrophysical transients of all types, a…
A lanthanide-rich kilonova in the aftermath of a long gamma-ray burst
Yu-Han Yang, Eleonora Troja, Brendan O'Connor +24
Kilonovae are a rare class of astrophysical transients powered by the radioactive decay of nuclei heavier than iron, synthesized in the merger of two compact objects. Over the firs…
