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…

Old and Bright: The Remarkable Radio Brightening of the Engine-driven SN 2012au Several Years After Explosion Signals the Birth of a PWN

Eli Wiston, Raffaella Margutti, A. J. Nayana +23

We present the results from an extensive broad-band (radio to X-rays) observing campaign of the engine-driven Type Ib SN 2012au in the first 13 years of evolution. The early-time (…

Discovery of 30 Repeating Fast Radio Burst Sources and Uniform Population Statistics of 80 Repeating Sources from CHIME/FRB

Amanda M. Cook, Kaitlyn Shin, Ziggy Pleunis +44

We present 30 newly discovered repeating fast radio burst (FRB) sources from the second catalog of bursts detected by the FRB backend on the Canadian Hydrogen Intensity Mapping Exp…

VLBI Observations of SN 2012au Reveal a Compact Radio Source a Decade Post Explosion

Mattias Lazda, Kenzie Nimmo, Maria R. Drout +13

Three leading models have been put forth to justify the observed radio re-brightening associated with stripped-envelope supernovae (SESNe) years post-explosion: radiation from an e…

A spatial filter for mitigating radio interference and its application to CHIME/FRB Outriggers

Shion Andrew, Juan Mena-Parra, Haochen Wang +16

The sensitivity of radio telescopes is becoming increasingly limited by the presence of radio frequency interference (RFI), which will worsen as the radio spectrum becomes more cro…

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…
