Spectral modelling of Cygnus A between 110 and 250 MHz. Impact on the LOFAR 21-cm signal power spectrum
E. Ceccotti, A. R. Offringa, L. V. E. Koopmans +15
Studying the redshifted 21-cm signal from the the neutral hydrogen during the Epoch of Reionization and Cosmic Dawn is fundamental for understanding the physics of the early univer…
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 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…
Limits on the ultra-bright Fast Radio Burst population from the CHIME Pathfinder
CHIME Scientific Collaboration, Mandana Amiri, Kevin Bandura +35
We present results from a new incoherent-beam Fast Radio Burst (FRB) search on the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Pathfinder. Its large instantaneous field…
Holographic Beam Mapping of the CHIME Pathfinder Array
Philippe Berger, Laura B. Newburgh, Mandana Amiri +32
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) Pathfinder radio telescope is currently surveying the northern hemisphere between 400 and 800 MHz. By mapping the large s…
A compression scheme for radio data in high performance computing
Kiyoshi Masui, Mandana Amiri, Liam Connor +11
We present a procedure for efficiently compressing astronomical radio data for high performance applications. Integrated, post-correlation data are first passed through a nearly lo…
Calibrating CHIME, A New Radio Interferometer to Probe Dark Energy
Laura B. Newburgh, Graeme E. Addison, Mandana Amiri +32
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a transit interferometer currently being built at the Dominion Radio Astrophysical Observatory (DRAO) in Penticton, BC…
