We present radio observations of the long-duration gamma-ray burst (GRB) 221009A which has become known to the community as the Brightest Of All Time or the BOAT. Our observations…
Characterization of the Repeating FRB 20220912A with the Allen Telescope Array
Sofia Z. Sheikh, Wael Farah, Alexander W. Pollak +17
FRB 20220912A is a repeating Fast Radio Burst (FRB) that was discovered in Fall 2022 and remained highly active for several months. We report the detection of 35 FRBs from 541 hour…
The expansion of the GRB 221009A afterglow
S. Giarratana, O. S. Salafia, M. Giroletti +14
We observed -ray burst (GRB) 221009A using very long baseline interferomety (VLBI) with the European VLBI Network (EVN) and the Very Long Baseline Array (VLBA), over a period sp…
Precise Measurements of Self-absorbed Rising Reverse Shock Emission from Gamma-ray Burst 221009A
Joe S. Bright, Lauren Rhodes, Wael Farah +18
The deaths of massive stars are sometimes accompanied by the launch of highly relativistic and collimated jets. If the jet is pointed towards Earth, we observe a "prompt" gamma-ray…
The ultra narrow FRB20191107B, and the origins of FRB scattering
Vivek Gupta, Chris Flynn, Wael Farah +4
We report the detection of FRB20191107B with the UTMOST radio telescope at a dispersion measure (DM) of 714.9 . The burst consists of three components, the bright…
Extremely band-limited repetition from a fast radio burst source
Pravir Kumar, Ryan M. Shannon, Chris Flynn +11
The fast radio burst (FRB) population is observationally divided into sources that have been observed to repeat and those that have not. There is tentative evidence that the bursts…
A population analysis of pulse broadening in ASKAP Fast Radio Bursts
Hao Qiu, Ryan M. Shannon, Wael Farah +8
The pulse morphology of fast radio bursts (FRBs) provides key information in both understanding progenitor physics and the plasma medium through which the burst propagates. We pres…
