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…

Correcting for Interstellar Scattering Delay in High-precision Pulsar Timing: Simulation Results

Nipuni Palliyaguru, Daniel Stinebring, Maura McLaughlin +2

Light travel time changes due to gravitational waves may be detected within the next decade through precision timing of millisecond pulsars. Removal of frequency-dependent interste…
