Unveiling the Local Environment of FRB 20220912A: Sub-arcsecond GHz Radio Continuum Mapping

Yash Bhusare, Yogesh Maan, Mohit Bhardwaj +4

The local environments of repeating fast radio bursts (FRBs) provide critical clues to their progenitors. While some active repeaters (e.g., FRB~20121102A, FRB~20190520B) are embed…

The Environments of Luminous Fast Blue Optical Transients: Evidence for a Compact Object and Wolf-Rayet Star Merger Origin

Anya E. Nugent, V. Ashley Villar, Brian D. Metzger +5

We present a comprehensive analysis of the host galaxies of 11 luminous fast blue optical transients (LFBOTs). We model new and archival host photometry and spectroscopy with Prosp…

FRB 20250316A: A Brilliant and Nearby One-Off Fast Radio Burst Localized to 13 parsec Precision

FRB Collaboration, Thomas C. Abbott, Daniel Amouyal +83

Precise localizations of a small number of repeating fast radio bursts (FRBs) using very long baseline interferometry (VLBI) have enabled multiwavelength follow-up observations rev…

Discovery and Localization of the Swift-Observed FRB 20241228A in a Star-forming Host Galaxy

Alice P. Curtin, Shion Andrew, Sunil Simha +27

On 2024 December 28, CHIME/FRB detected the thus-far non-repeating FRB 20241228A with a real-time signal-to-noise ratio of . Approximately 112~s later, the X-ray Telescope onb…

A Repeating Fast Radio Burst Source in a Low-Luminosity Dwarf Galaxy

Danté M. Hewitt, Mohit Bhardwaj, Alexa C. Gordon +48

We present the localization and host galaxy of FRB 20190208A, a repeating source of fast radio bursts (FRBs) discovered using CHIME/FRB. As part of the PRECISE repeater localizatio…

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…
