The NANOGrav 12.5-Year Data Set: Monitoring Interstellar Scattering Delays
Jacob E. Turner, Maura A. McLaughlin, James M. Cordes +33
We extract interstellar scintillation parameters for pulsars observed by the NANOGrav radio pulsar timing program. Dynamic spectra for the observing epochs of each pulsar were used…
First discovery of new pulsars and RRATs with CHIME/FRB
D. C. Good, B. C. Andersen, P. Chawla +20
We report the discovery of seven new Galactic pulsars with the Canadian Hydrogen Intensity Mapping Experiment's Fast Radio Burst backend (CHIME/FRB). These sources were first ident…
Astrophysics Milestones For Pulsar Timing Array Gravitational Wave Detection
Nihan S. Pol, Stephen R. Taylor, Luke Zoltan Kelley +49
The NANOGrav Collaboration reported strong Bayesian evidence for a common-spectrum stochastic process in its 12.5-yr pulsar timing array dataset, with median characteristic strain…
The Discovery of Nulling and Mode Switching Pulsars with CHIME/Pulsar
C. Ng, B. Wu, M. Ma +18
The Pulsar backend of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has monitored hundreds of known pulsars in the northern sky since Fall 2018, providing a rich data…
The NANOGrav 12.5-year Data Set: Search For An Isotropic Stochastic Gravitational-Wave Background
Zaven Arzoumanian, Paul T. Baker, Harsha Blumer +58
We search for an isotropic stochastic gravitational-wave background (GWB) in the -year pulsar timing data set collected by the North American Nanohertz Observatory for Gravit…
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…
