The NANOGrav 15 yr Dataset: Modified Functional Forms for Profile-Evolution Time Delays in Pulsar Timing Models
Sofia V. Sosa Fiscella, Michael T. Lam, Olivia West +49
Radio pulsars exhibit frequency-dependent variations in the shape of their pulse profiles that introduce systematic delays in the observed pulse times of arrival (TOA) across an ob…
Optimal Pulsar Timing Array Strategies with the Deep Synoptic Array
Tyler Cohen, Paul B. Demorest, Jeremy G. Baier +50
Pulsar timing array (PTA) experiments have seen evidence for a nanohertz-frequency gravitational wave background (GWB) through coordinated radio timing observations of millisecond…
Constraints on Supermassive Black Hole Binaries from the Lack of Resolvable Sources in the NANOGrav 15-yr Dataset
Emiko C. Gardiner, Kayhan Gültekin, Philippe Turgeon +116
Pulsar timing arrays (PTAs) have found evidence of a gravitational wave background (GWB) consistent with a population of supermassive black hole binaries (SMBHBs), but have not yet…
A NICER view of PSR J16142230: a massive and compact millisecond pulsar
Lucien Mauviard, Sebastien Guillot, Lami Suleiman +17
Using pulse profile modeling, we obtain the mass-radius measurement of a millisecond pulsar (MSP) with data from the Neutron Star Interior Composition ExploreR, XMM-Newton and the…
Pulsar Timing Array Sensitivity to Anisotropy: Empirical Sensitivity Curves, Scaling Relations, and the Multi-Resolution Pixel Basis
Taha T. Moursy, Nihan S. Pol, Gabriella Agazie +115
We quantify pulsar timing array (PTA) sensitivity to anisotropy in the gravitational wave background using the cross-correlation based Fisher information matrix in the pixel and sp…
Evaluating the Fourier Approximation in Pulsar Timing Array Analysis
Yongqi Zhang, Hayden Scholz, Ken D. Olum +53
Pulsar timing arrays search for stochastic processes such as gravitational waves by comparing pulse time of arrival data for millisecond pulsars to expectations from a background w…
