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…
Overview of the Canadian Hydrogen Observatory and Radio Transient Detector (CHORD) Project
The CHORD Collaboration, Kevin Bandura, Leonid Belostotski +49
The Canadian Hydrogen Observatory and Radio-transient Detector (CHORD) is a next-generation wideband radio interferometer currently being constructed and commissioned at the Domini…
CHIME/Slow overview and pilot survey: A new backend to search for second-duration radio transients with the CHIME telescope
Sujay Mate, Kevin Luke, Yash Bhusare +23
We present an overview of CHIME/Slow, a real-time transient search backend under development to search for second-duration radio transients using the CHIME telescope, and results o…
The Astrophysics of Fast Radio Bursts
Alice P. Curtin, Marcin GawroÅski, Jason Hessels +11
Fast radio bursts (FRBs) provide a glimpse of high-energy astrophysical phenomena in other galaxies. They point the way to extreme conditions that are currently undetectable by any…
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…
Tied-array beam flatfielding
Dirk Kuiper, Cees Bassa, Ziggy Pleunis +1
Context. Multi-element phased-array radio telescopes use digital beamforming to widen their field-of-view with numerous tied-array beams (TABs). These beams share bandpass variatio…
