Strong-field Gravity Tests with the Double Pulsar

M. Kramer, I. H. Stairs, R. N. Manchester +27

Continued observations of the Double Pulsar, PSR J0737-3039A/B, consisting of two radio pulsars (A and B) that orbit each other with a period of 2.45hr in a mildly eccentric (e=0.0…

Noise analysis in the European Pulsar Timing Array data release 2 and its implications on the gravitational-wave background search

A. Chalumeau, S. Babak, A. Petiteau +49

The European Pulsar Timing Array (EPTA) collaboration has recently released an extended data set for six pulsars (DR2) and reported evidence for a common red noise signal. Here we…

Searches for Gravitational Waves from Known Pulsars at Two Harmonics in the Second and Third LIGO-Virgo Observing Runs

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1694

We present a targeted search for continuous gravitational waves (GWs) from 236 pulsars using data from the third observing run of LIGO and Virgo (O3) combined with data from the se…

Common-red-signal analysis with 24-yr high-precision timing of the European Pulsar Timing Array: Inferences in the stochastic gravitational-wave background search

S. Chen, R. N. Caballero, Y. J. Guo +49

We present results from the search for a stochastic gravitational-wave background (GWB) as predicted by the theory of General Relativity using six radio millisecond pulsars from th…

Dual-frequency single-pulse study of PSR B0950+08

A. V. Bilous, J. M. Griessmeier, T. Pennucci +33

PSR B0950+08 is a bright non-recycled pulsar whose single-pulse fluence variability is reportedly large. Based on observations at two widely separated frequencies, 55 MHz (NenuFAR)…

A broadband radio study of PSR J0250+5854: the slowest-spinning radio pulsar known

C. H. Agar, P. Weltevrede, L. Bondonneau +19

We present radio observations of the most slowly rotating known radio pulsar PSR J0250+5854. With a 23.5 s period, it is close, or even beyond, the - diagram region tho…

Search for Very High-Energy Emission from the millisecond pulsar PSR J0218+4232

V. A. Acciari, S. Ansoldi, L. A. Antonelli +198

PSR J0218+4232 is one of the most energetic millisecond pulsars known and has long been considered as one of the best candidates for very high-energy (VHE; >100 GeV) gamma-ray emis…

Follow-up of 27 radio-quiet gamma-ray pulsars at 110-190 MHz using the international LOFAR station FR606

J. -M. Grießmeier, D. A. Smith, G. Theureau +5

The Fermi Large Area Telescope has detected over 260 gamma-ray pulsars. About one quarter of these are labeled as radio-quiet. In the population of nonrecycled gamma-ray pulsars, t…

PSR J2222--0137. I. Improved physical parameters for the system

Y. J. Guo, P. C. C. Freire, L. Guillemot +14

The PSR J2222-0137 binary system is a unique laboratory for testing gravity theories. To fully exploit its potential for the tests, we aim to improve the measurements of its physic…

NICER Detection of Thermal X-ray Pulsations from the Massive Millisecond Pulsars PSR J0740+6620 and PSR J1614-2230

M. T. Wolff, S. Guillot, S. Bogdanov +11

We report the detection of X-ray pulsations from the rotation-powered millisecond-period pulsars PSR J0740+6620 and PSR J1614-2230, two of the most massive neutron stars known, usi…

A NICER View of the Massive Pulsar PSR J0740+6620 Informed by Radio Timing and XMM-Newton Spectroscopy

Thomas E. Riley, Anna L. Watts, Paul S. Ray +27

We report on Bayesian estimation of the radius, mass, and hot surface regions of the massive millisecond pulsar PSR J07406620, conditional on pulse-profile modeling of Neutron S…

Refined Mass and Geometric Measurements of the High-Mass PSR J0740+6620

Emmanuel Fonseca, H. Thankful Cromartie, Timothy T. Pennucci +42

We report results from continued timing observations of PSR J0740+6620, a high-mass, 2.8-ms radio pulsar in orbit with a likely ultra-cool white dwarf companion. Our data set consi…
