The International Pulsar Timing Array second data release: Search for an isotropic Gravitational Wave Background
J. Antoniadis, Z. Arzoumanian, S. Babak +123
We searched for an isotropic stochastic gravitational wave background in the second data release of the International Pulsar Timing Array, a global collaboration synthesizing decad…
Timing of young radio pulsars II. Braking indices and their interpretation
A. Parthasarathy, S. Johnston, R. M. Shannon +8
In Paper I of this series, we detected a significant value of the braking index () for 19 young, high- radio pulsars using 10 years of timing observations from t…
The International Pulsar Timing Array: Second data release
B. B. P. Perera, M. E. DeCesar, P. B. Demorest +72
In this paper, we describe the International Pulsar Timing Array second data release, which includes recent pulsar timing data obtained by three regional consortia: the European Pu…
Timing of young radio pulsars I: Timing noise, periodic modulation and proper motion
A. Parthasarathy, R. M. Shannon, S. Johnston +9
The smooth spin-down of young pulsars is perturbed by two non-deterministic phenomenon, glitches and timing noise. Although the timing noise provides insights into nuclear and plas…
Improving timing sensitivity in the microhertz frequency regime: limits from PSR J17130747 on gravitational waves produced by super-massive black-hole binaries
B. B. P. Perera, B. W. Stappers, S. Babak +25
We search for continuous gravitational waves (CGWs) produced by individual super-massive black-hole binaries (SMBHBs) in circular orbits using high-cadence timing observations of P…
Tests of Gravitational Symmetries with Pulsar Binary J1713+0747
W. W. Zhu, G. Desvignes, N. Wex +50
Symmetries play an important role in modern theories of gravity. The strong equivalence principle (SEP) constitutes a collection of gravitational symmetries which are all implement…
The disturbance of a millisecond pulsar magnetosphere
R. M. Shannon, L. T. Lentati, M. Kerr +21
Pulsar timing has enabled some of the strongest tests of fundamental physics. Central to the technique is the assumption that the detected radio pulses can be used to accurately me…
A glitch in the millisecond pulsar J0613-0200
J. W. McKee, G. H. Janssen, B. W. Stappers +17
We present evidence for a small glitch in the spin evolution of the millisecond pulsar J06130200, using the EPTA Data Release 1.0, combined with Jodrell Bank analogue filterbank…
Characterising the rotational irregularities of the Vela pulsar from 21 yr of phase-coherent timing
R. M. Shannon, L. T. Lentati, M. Kerr +3
Pulsars show two classes of rotational irregularities that can be used to understand neutron-star interiors and magnetospheres: glitches and timing noise. Here we present an analys…
A millisecond pulsar in an extremely wide binary system
C. G. Bassa, G. H. Janssen, B. W. Stappers +30
We report on 22 yrs of radio timing observations of the millisecond pulsar J10240719 by the telescopes participating in the European Pulsar Timing Array (EPTA). These observatio…
Limits on anisotropy in the nanohertz stochastic gravitational-wave background
S. R. Taylor, C. M. F. Mingarelli, J. R. Gair +32
The paucity of observed supermassive black hole binaries (SMBHBs) may imply that the gravitational wave background (GWB) from this population is anisotropic, rendering existing ana…
Field and Globular Cluster LMXBs in NGC 4278
G. Fabbiano, N. J. Brassington, L. Lentati +12
We report a detailed spectral analysis of the population of low-mass X-ray binaries (LMXBs) detected in the elliptical galaxy NGC~4278 with Chandra. Seven luminous sources were stu…
