A Detection of Cosmological 21 cm Emission from CHIME in Cross-correlation with eBOSS Measurements of the Lyman- Forest
CHIME Collaboration, Mandana Amiri, Kevin Bandura +28
We report the detection of 21 cm emission at an average redshift in the cross-correlation of data from the Canadian Hydrogen Intensity Mapping Experiment (CHIME) wi…
CHIME/FRB Discovery of 25 Repeating Fast Radio Burst Sources
FRB Collaboration, Bridget C. Andersen, Kevin Bandura +56
We present the discovery of 25 new repeating fast radio burst (FRB) sources found among CHIME/FRB events detected between 2019 September 30 and 2021 May 1. The sources were found u…
Power-law distribution and scale-invariant structure from the first CHIME/FRB Fast Radio Burst catalog
Zi-Han Wang, Yu Sang, Xue Zhang
We study the statistical property of fast radio bursts (FRBs) based on a selected sample of 190 one-off FRBs in the first CHIME/FRB catalog. Three power law models are used in the…
Detection of Cosmological 21 cm Emission with the Canadian Hydrogen Intensity Mapping Experiment
CHIME Collaboration, Mandana Amiri, Kevin Bandura +30
We present a detection of 21-cm emission from large-scale structure (LSS) between redshift 0.78 and 1.43 made with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). Radio…
Using the Sun to Measure the Primary Beam Response of the Canadian Hydrogen Intensity Mapping Experiment
CHIME Collaboration, Mandana Amiri, Kevin Bandura +27
We present a beam pattern measurement of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) made using the Sun as a calibration source. As CHIME is a pure drift scan instru…
An Overview of CHIME, the Canadian Hydrogen Intensity Mapping Experiment
The CHIME Collaboration, Mandana Amiri, Kevin Bandura +40
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a drift scan radio telescope operating across the 400-800 MHz band. CHIME is located at the Dominion Radio Astrophysic…
The First CHIME/FRB Fast Radio Burst Catalog
FRB Collaboration, Mandana Amiri, Bridget C. Andersen +73
We present a catalog of 536 fast radio bursts (FRBs) detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) Project between 400 and 800 MHz fro…
The CHIME Pulsar Project: System Overview
Pulsar Collaboration, M. Amiri, K. M. Bandura +42
We present the design, implementation and performance of a digital backend constructed for the Canadian Hydrogen Intensity Mapping Experiment (CHIME) that uses accelerated computin…
A bright millisecond-duration radio burst from a Galactic magnetar
FRB Collaboration, B. C. Andersen, K. M. Bandura +68
Magnetars are highly magnetized young neutron stars that occasionally produce enormous bursts and flares of X-rays and gamma-rays. Of the approximately thirty magnetars currently k…
Periodic activity from a fast radio burst source
FRB Collaboration, M. Amiri, B. C. Andersen +70
Fast radio bursts (FRBs) are bright, millisecond-duration radio transients originating from extragalactic distances. Their origin is unknown. Some FRB sources emit repeat bursts, r…
CHIME/FRB Detection of Eight New Repeating Fast Radio Burst Sources
FRB Collaboration, B. C. Andersen, K. Bandura +54
We report on the discovery of eight repeating fast radio burst (FRB) sources found using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope. These sources span a…
Observations of Fast Radio Bursts at Frequencies down to 400 Megahertz
FRB Collaboration, Mandana Amiri, Kevin Bandura +52
Fast radio bursts (FRBs) are highly dispersed millisecond-duration radio flashes likely arriving from far outside the Milky Way galaxy. This phenomenon was discovered at radio freq…
The CHIME Fast Radio Burst Project: System Overview
FRB Collaboration, M. Amiri, K. Bandura +49
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a novel transit radio telescope operating across the 400-800-MHz band. CHIME is comprised of four 20-m x 100-m semi-cy…
