The CHIME/FRB Outriggers: Commissioning the Hat Creek Outrigger and an Updated Calibration Scheme for Mitigating RFI
Mattias Lazda, Nina V. Gusinskaia, Gurman Sachdeva +25
This work presents commissioning of the Hat Creek Outrigger (HCO), a dual-polarization 256-element radio interferometer that is part of the Canadian Hydrogen Intensity Mapping Expe…
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…
Evidence for Enhancement in the Rate of Fast Radio Bursts Toward Galaxy Clusters
Mawson W. Sammons, Airene Ahuja, Matt Dobbs +25
Massive galaxy clusters can introduce gravitational lensing and populations of suppressed star formation member galaxies into the line of sight, potentially changing the distributi…
Unveiling the Local Environment of FRB 20220912A: Sub-arcsecond GHz Radio Continuum Mapping
Yash Bhusare, Yogesh Maan, Mohit Bhardwaj +4
The local environments of repeating fast radio bursts (FRBs) provide critical clues to their progenitors. While some active repeaters (e.g., FRB~20121102A, FRB~20190520B) are embed…
Debiasing the Observed Fast Radio Burst Population with the CHIME/FRB Selection Function
Kyle McGregor, Jason W. T. Hessels, Victoria M. Kaspi +26
The recent release of CHIME/FRB Catalog~2 provides the largest sample to date with which to investigate the intrinsic distributions of fast radio bursts (FRBs). Leveraging an expan…
Multimodal Transformer Based Generic Mixture Density Network for Scattering Timescale Estimation of Fast Radio Bursts
Bikash Kharel, Emmanuel Fonseca, Srinjoy Das +5
The discovery rate of fast radio bursts (FRBs) continues to increase with the advent of new radio facilities and yet extracting their astrophysical parameters such as scattering ti…
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…
Radio Monitoring Campaign of Active Repeater FRB 20220912A with CHIME
Thomas C. Abbott, Aaron B. Pearlman, Victoria M. Kaspi +20
FRB 20220912A is a highly active repeating fast radio burst (FRB) source, discovered by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) using its real-time FRB detection…
A Neural Score-Based Particle Method for the Vlasov-Maxwell-Landau System
Vasily Ilin, Jingwei Hu
Plasma modeling is central to the design of nuclear fusion reactors, yet simulating collisional plasma kinetics from first principles remains a formidable computational challenge:…
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…
Constraining the mass of the M31 ionized baryon Halo using CHIME/FRB Catalog 2
Lordrick A. Kahinga, J. Xavier Prochaska, Sunil Simha +21
The circumgalactic medium (CGM) surrounding galaxies is believed to be a significant reservoir of baryons, yet its total mass remains poorly constrained. We present a novel approac…
Probing the maximum energy of fast radio bursts using thousands of sources from the Second CHIME/FRB Catalog
Vishwangi Shah, Jason W. T. Hessels, Victoria M. Kaspi +25
Quantifying the maximum energy of fast radio bursts (FRBs) can provide stringent constraints on their emission mechanisms and progenitor models. However, the most energetic bursts…
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 Second CHIME/FRB Catalog of Fast Radio Bursts
FRB Collaboration, Thomas Abbott, Bridget C. Andersen +71
We present a catalog of 4539 fast radio bursts (FRBs) observed with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope between 25 July 2018 and 15 September 2023.…
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…
Constraining Gas Mass Fractions in Galaxy Groups and Clusters with the First CHIME/FRB Outrigger
Adam E. Lanman, Sunil Simha, Kiyoshi W. Masui +16
In recent years, localized fast radio bursts (FRBs) have emerged as a powerful tool to study the structure of the baryonic matter in the universe. Their dispersion measures (DMs) s…
