Discovery of an Extremely Luminous Sporadic Radio Pulsar

Fengqiu Adam Dong, Robert Main, Jackson D. Taylor +25

We have discovered PSR J2108+5055, an extremely luminous but sporadic mode-changing rotating radio transient (RRAT), with a period of 0.495 s using the Canadian Hydrogen Intensity…

A steadily declining dispersion measure for the repeating fast radio burst FRB 20220529A: Evidence for an FRB engine embedded in an expanding supernova remnant

Ayush Pandhi, Kenzie Nimmo, Shion Andrew +29

We present the discovery and subsequent 3.2 year monitoring campaign of the repeating fast radio burst FRB 20220529A with CHIME/FRB. We observe a gradual dispersion measure (DM) de…

Exploring selection biases in FRB dispersion-galaxy cross-correlations with magnetohydrodynamical simulations

April Qiu Cheng, Shion Elizabeth Andrew, Haochen Wang +1

The dispersion measure (DM) of fast radio bursts (FRBs) in conjunction with their redshifts can be used as powerful probes of the distribution of extragalactic plasma. With a large…

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…

James Webb Space Telescope Observations of the Nearby and Precisely-Localized FRB 20250316A: A Potential Near-IR Counterpart and Implications for the Progenitors of Fast Radio Bursts

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…
