Detection of Partial Coherence due to Multipath Propagation for FRB 20220413B with CHIME/FRB
Zarif Kader, Evan Davies-Velie, Matt Dobbs +7
Fast radio bursts (FRBs) are a millisecond-long transient phenomenon that propagate across extragalactic distances and are effectively a point source. Radio wave propagation…
Nulling baryonic feedback in weak lensing surveys using cross-correlations with fast radio bursts
Calvin Leung, Josh Borrow, Kiyoshi W. Masui +4
Baryonic feedback is a leading contaminant in studying dark matter and cosmology using cosmic shear. This has meant omitting much of the data during cosmological inference, or forw…

CHIME/FRB Discovery of an Unusual Circularly Polarized Long-Period Radio Transient with an Accelerating Spin Period
Fengqiu Adam Dong, Kaitlyn Shin, Casey Law +20
We report the discovery of CHIME J1634+44, a Long Period Radio Transient (LPT) unique for two aspects: it is the first known LPT to emit fully circularly polarized radio bursts, an…
Echoes in Different Tempo: Long-Term Monitoring of Crab Echoes with CHIME
Thierry Serafin Nadeau, Marten H. van Kerkwijk, Jing Luo +4
The Crab Pulsar is known to feature plasma lensing events known as echoes. These events are characterized by additional components in the pulse profile which are produced by additi…
Constraining the Faint-End Slope of the FRB Energy Function Using CHIME/FRB Catalog-1 and Local Volume Galaxies
Mohit Bhardwaj, Victoria M. Kaspi, K. W. Masui +3
Despite hundreds of detected fast radio bursts (FRBs), the faint-end slope () of their energy distribution remains poorly constrained, hindering understanding of whether bright,…

Peter K. Blanchard, Edo Berger, Shion E. Andrew +23
We present deep James Webb Space Telescope near-infrared imaging to search for a quiescent or transient counterpart to FRB 20250316A, which was precisely localized with the CHIME/F…
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
