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…
Solar-System Studies with Pulsar Timing Arrays
R. N. Caballero
High-precision pulsar timing is central to a wide range of astrophysics and fundamental physics applications. When timing an ensemble of millisecond pulsars in different sky positi…
A dynamical approach in exploring the unknown mass in the Solar system using pulsar timing arrays
Y. J. Guo, K. J. Lee, R. N. Caballero
The error in the Solar system ephemeris will lead to dipolar correlations in the residuals of pulsar timing array for widely separated pulsars. In this paper, we utilize such corre…
From Spin Noise to Systematics: Stochastic Processes in the First International Pulsar Timing Array Data Release
L. Lentati, R. M. Shannon, W. A. Coles +80
We analyse the stochastic properties of the 49 pulsars that comprise the first International Pulsar Timing Array (IPTA) data release. We use Bayesian methodology, performing model…
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…
Prospects for High-Precision Pulsar Timing with the New Effelsberg PSRIX Backend
P. Lazarus, R. Karuppusamy, E. Graikou +5
The PSRIX backend is the primary pulsar timing instrument of the Effelsberg 100-m radio telescope since early 2011. This new ROACH-based system enables bandwidths up to 500 MHz to…
The noise properties of 42 millisecond pulsars from the European Pulsar Timing Array and their impact on gravitational wave searches
R. N. Caballero, K. J. Lee, L. Lentati +36
The sensitivity of Pulsar Timing Arrays to gravitational waves depends on the noise present in the individual pulsar timing data. Noise may be either intrinsic or extrinsic to the…
