Scintillation Timescales of Bright FRBs Detected by CHIME/FRB
Eve Schoen, Calvin Leung, Kiyoshi Masui +5
We describe a pipeline to measure scintillation in fast radio bursts (FRBs) detected by CHIME/FRB in the 400-800 MHz band by analyzing the frequency structure of the FRB's spectrum…
Multiband Detection of Repeating FRB 20180916B
Ketan R. Sand, Jakob Faber, Vishal Gajjar +19
We present a multiband study of FRB 20180916B, a repeating source with a 16.3 day periodicity. We report the detection of 4, 1 and 7 bursts from observations spanning 3 days using…
Axion dark matter-induced echo of supernova remnants
Yitian Sun, Katelin Schutz, Anjali Nambrath +2
Axions are a theoretically promising dark matter (DM) candidate. In the presence of radiation from bright astrophysical sources at radio frequencies, nonrelativistic DM axions can…
A clock stabilization system for CHIME/FRB Outriggers
J. Mena-Parra, C. Leung, S. Cary +12
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has emerged as the prime telescope for detecting fast radio bursts (FRBs). CHIME/FRB Outriggers will be a dedicated very-…
Evaluating and Enhancing Candidate Clocking Systems for CHIME/FRB VLBI Outriggers
Savannah Cary, Juan Mena-Parra, Calvin Leung +3
As the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has become the leading instrument for detecting Fast Radio Bursts (FRBs), CHIME/FRB Outriggers will use very-long-base…
A sudden period of high activity from repeating Fast Radio Burst 20201124A
Adam E. Lanman, Bridget C. Andersen, Pragya Chawla +30
The repeating FRB 20201124A was first discovered by CHIME/FRB in November of 2020, after which it was seen to repeat a few times over several months. It entered a period of high ac…
