Robust Estimation of Scattering in Pulsar Timing Analysis
L. Lentati, M. Kerr, S. Dai +3
We present a robust approach to incorporating models for the time-variable broadening of the pulse profile due to scattering in the ionized interstellar medium into profile-domain…
Wide-band Profile Domain Pulsar Timing Analysis
L. Lentati, M. Kerr, S. Dai +22
We extend profile domain pulsar timing to incorporate wide-band effects such as frequency-dependent profile evolution and broadband shape variation in the pulse profile. We also in…
All correlations must die: Assessing the significance of a stochastic gravitational-wave background in pulsar-timing arrays
S. R. Taylor, L. Lentati, S. Babak +4
We present two methods for determining the significance of a stochastic gravitational-wave (GW) background affecting a pulsar-timing array, where detection is based on evidence for…
Proper motions of 15 pulsars: a comparison between Bayesian and frequentist algorithms
L. Li, N. Wang, J. P. Yuan +4
We present proper motions for 15 pulsars which are observed regularly by the Nanshan 25-m radio telescope. Two methods, the frequentist method (Coles et al.2011) and the Bayesian (…
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…
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…
Profile Stochasticity in PSR J1909-3744
L. Lentati, R. M. Shannon
We extend the recently introduced Bayesian framework `Generative Pulsar Timing Analysis' to incorporate both pulse jitter (high frequency variation in the arrival time of the pulse…
Generative pulsar timing analysis
L Lentati, P. Alexander, M. P. Hobson
A new Bayesian method for the analysis of folded pulsar timing data is presented that allows for the simultaneous evaluation of evolution in the pulse profile in either frequency o…
A Bayesian blind survey for cold molecular gas in the Universe
Lindley Lentati, Chris Carilli, Paul Alexander +2
A new Bayesian method for performing an image domain search for line-emitting galaxies is presented. The method uses both spatial and spectral information to robustly determine the…
Bayesian estimation of non-Gaussianity in pulsar timing analysis
Lindley Lentati, Michael P. Hobson, Paul Alexander
We introduce a method for performing a robust Bayesian analysis of non-Gaussianity present in pulsar timing data, simultaneously with the pulsar timing model, and additional stocha…
Model-based asymptotically optimal dispersion measure correction for pulsar timing
K. J. Lee, C. G. Bassa, G. H. Janssen +8
In order to reach the sensitivity required to detect gravitational waves, pulsar timing array experiments need to mitigate as much noise as possible in timing data. A dominant amou…
How to take the interstellar weather with you in pulsar timing analysis
Lindley Lentati, Paul Alexander, Michael P. Hobson
Here we present a Bayesian method of including discrete measurements of dispersion measure due to the interstellar medium in the direction of a pulsar as prior information in the a…
TempoNest: A Bayesian approach to pulsar timing analysis
Lindley Lentati, Paul Alexander, Michael P. Hobson +4
A new Bayesian software package for the analysis of pulsar timing data is presented in the form of TempoNest which allows for the robust determination of the non-linear pulsar timi…
