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…

The NANOGrav 12.5-year Data Set: Chromatic Noise Characterization & Mitigation with Time-Domain Kernels

Jeffrey S. Hazboun, Joseph Simon, Jeremy Baier +64

Pulsar timing arrays (PTAs) have recently entered the detection era, quickly moving beyond the goal of simply improving sensitivity at the lowest frequencies for the sake of observ…

PINT: Maximum-likelihood estimation of pulsar timing noise parameters

Abhimanyu Susobhanan, David Kaplan, Anne Archibald +21

PINT is a pure-Python framework for high-precision pulsar timing developed on top of widely used and well-tested Python libraries, supporting both interactive and programmatic data…

A pulsar-based timescale from the International Pulsar Timing Array

G. Hobbs, L. Guo, R. N. Caballero +56

We have constructed a new timescale, TT(IPTA16), based on observations of radio pulsars presented in the first data release from the International Pulsar Timing Array (IPTA). We us…

On-the-Fly Mapping of New Pulsars

Joseph K. Swiggum, Peter A. Gentile

Current single dish, low-frequency radio pulsar surveys provide efficient sky coverage, but poor localization of new discoveries. Here, we describe a practical technique for rapidl…

A Gaussian Mixture Model for Nulling Pulsars

David L. Kaplan, Joseph K. Swiggum, Travis D. J. Fichtenbauer +1

The phenomenon of pulsar nulling -- where pulsars occasionally turn off for one or more pulses -- provides insight into pulsar-emission mechanisms and the processes by which pulsar…

The International Pulsar Timing Array: First Data Release

J. P. W. Verbiest, L. Lentati, G. Hobbs +89

The highly stable spin of neutron stars can be exploited for a variety of (astro-)physical investigations. In particular arrays of pulsars with rotational periods of the order of m…

The NANOGrav Nine-year Data Set: Observations, Arrival Time Measurements, and Analysis of 37 Millisecond Pulsars

Z. Arzoumanian, A. Brazier, S. Burke-Spolaor +41

We present high-precision timing observations spanning up to nine years for 37 millisecond pulsars monitored with the Green Bank and Arecibo radio telescopes as part of the North A…

PsrPopPy: An open-source package for pulsar population simulations

Sam Bates, Duncan Lorimer, Akshaya Rane +1

We have produced a new software package for the simulation of pulsar populations, \textsc{PsrPopPy}, based on the \textsc{Psrpop} package. The codebase has been re-written in Pytho…
