FRB 20210601A: Extreme Temporal Clustering in a Repeating Fast Radio Burst Source as Evidence for a Hidden Class of Episodic Repeaters
Ryan Mckinven, Amanda M. Cook, Alice P. Curtin +29
Population studies of fast radio burst (FRB) repetition typically model sources using a single distribution of steady, time-averaged burst rates, yet individual sources show signif…
A targeted search for fast radio bursts from magnetars in elliptical galaxies
S. Paine, D. R. Lorimer, S. Sirota +12
Motivated by predictions that globular clusters associated with nearby giant elliptical galaxies are prime environments for detecting fast radio bursts (FRBs) from magnetars, we re…
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…
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…
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.…
A Spatial Gap in the Sky Distribution of Fast Radio Burst Detections Coinciding with Galactic Plasma Overdensities
Swarali Shivraj Patil, Robert A. Main, Emmanuel Fonseca +26
We analyze the positional and morphological properties of about 3600 unique fast radio burst (FRB) sources reported in the second FRB catalog generated by the Canadian Hydrogen Int…
Repeating versus Nonrepeating Fast Radio Bursts: A Deep Learning Approach to Morphological Characterization
Bikash Kharel, Emmanuel Fonseca, Charanjot Brar +6
We present a deep learning approach to classify fast radio bursts (FRBs) based purely on morphology as encoded on recorded dynamic spectrum from CHIME/FRB Catalog 2. We implemented…
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…
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…
The CHIME/FRB Discovery of the Extremely Active Fast Radio Burst Source FRB 20240114A
Kaitlyn Shin, Alice Curtin, Maxwell Fine +28
Among the thousands of observed fast radio bursts (FRBs), a few sources exhibit exceptionally high burst activity observable by many telescopes across a broad range of radio freque…
The Massive and Quiescent Elliptical Host Galaxy of the Repeating Fast Radio Burst FRB20240209A
T. Eftekhari, Y. Dong, W. Fong +39
The discovery and localization of FRB20240209A by the Canadian Hydrogen Intensity Mapping Fast Radio Burst (CHIME/FRB) experiment marks the first repeating FRB localized with the C…
Rare Event Classification with Weighted Logistic Regression for Identifying Repeating Fast Radio Bursts
Antonio Herrera-Martin, Radu V. Craiu, Gwendolyn M. Eadie +8
An important task in the study of fast radio bursts (FRBs) remains the automatic classification of repeating and non-repeating sources based on their morphological properties. We p…
Investigating the sightline of a highly scattered FRB through a filamentary structure in the local Universe
Kaitlyn Shin, Calvin Leung, Sunil Simha +31
Fast radio bursts (FRBs) are unique probes of extragalactic ionized baryonic structure as each signal, through its burst properties, holds information about the ionized matter it e…
A pulsar-like swing in the polarisation position angle of a nearby fast radio burst
Ryan Mckinven, Mohit Bhardwaj, Tarraneh Eftekhari +41
Fast radio bursts (FRBs) last for milliseconds and arrive at Earth from cosmological distances. While their origin(s) and emission mechanism(s) are presently unknown, their signals…
Modeling the Morphology of Fast Radio Bursts and Radio Pulsars with fitburst
Emmanuel Fonseca, Ziggy Pleunis, Daniela Breitman +11
We present a framework for modeling astrophysical pulses from radio pulsars and fast radio bursts (FRBs). This framework, called fitburst, generates synthetic representations of dy…
