The NANOGrav Nine-Year Data Set: Noise Budget for Pulsar Arrival Times on Intraday Timescales
M. T. Lam, J. M. Cordes, S. Chatterjee +21
The use of pulsars as astrophysical clocks for gravitational wave experiments demands the highest possible timing precision. Pulse times of arrival (TOAs) are limited by stochastic…
Properties and Evolution of the Redback Millisecond Pulsar Binary PSR J2129-0429
Eric C. Bellm, David L. Kaplan, Rene P. Breton +19
PSR J2129-0429 is a "redback" eclipsing millisecond pulsar binary with an unusually long 15.2 hour orbit. It was discovered by the Green Bank Telescope in a targeted search of unid…
The Feasibility of Using Black Widow Pulsars in Pulsar Timing Arrays for Gravitational Wave Detection
Christopher Bochenek, Scott Ransom, Paul Demorest
In the past five years, approximately one third of the 65 pulsars discovered by radio observations of Fermi unassociated sources are black widow pulsars (BWPs). BWPs are binary mil…
The NANOGrav Nine-year Data Set: Astrometric Measurements of 37 Millisecond Pulsars
Allison M. Matthews, David J. Nice, Emmanuel Fonseca +18
Using the nine-year radio-pulsar timing data set from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), collected at Arecibo Observatory and the Green Ba…
The GMRT High Resolution Southern Sky Survey for pulsars and transients -I. Survey description and initial discoveries
Bhaswati Bhattacharyya, Sally Cooper, Mateusz Malenta +8
We are conducting a survey for pulsars and transients using the Giant Metrewave Radio Telescope (GMRT). The GMRT High Resolution Southern Sky (GHRSS) survey is an off-Galactic-plan…
Single-Source Gravitational Wave Limits from the J1713+0747 24-hr Global Campaign
T. Dolch, J. A. Ellis, S. Chatterjee +34
Dense, continuous pulsar timing observations over a 24-hr period provide a method for probing intermediate gravitational wave (GW) frequencies from 10 microhertz to 20 millihertz.…
