Prospects for a survey of the Galactic plane with the Cherenkov Telescope Array

CTA Consortium

Approximately one hundred sources of very-high-energy (VHE) gamma rays are known in the Milky Way. A survey of the entire Galactic Plane in the energy range from a few tens of GeV…

Constraining the magnetic field geometry of the millisecond pulsar PSR~J0030+0451 from joint radio, thermal X-ray and -ray emission

J. Pétri, S. Guillot, L. Guillemot +13

With the advent of multi-wavelength electromagnetic observations of neutron stars, spanning many decades in photon energies, from radio wavelengths up to X-rays and -rays, it be…

The second data release from the European Pulsar Timing Array II. Customised pulsar noise models for spatially correlated gravitational waves

J. Antoniadis, P. Arumugam, S. Arumugam +95

The nanohertz gravitational wave background (GWB) is expected to be an aggregate signal of an ensemble of gravitational waves emitted predominantly by a large population of coalesc…

The second data release from the European Pulsar Timing Array I. The dataset and timing analysis

J. Antoniadis, S. Babak, A. -S. Bak Nielsen +66

Pulsar timing arrays offer a probe of the low-frequency gravitational wave spectrum (1 - 100 nanohertz), which is intimately connected to a number of markers that can uniquely trac…

Variable Scintillation Arcs of Millisecond Pulsars observed with the Large European Array for Pulsars

R. A. Main, J. Antoniadis, S. Chen +26

We present the first large sample of scintillation arcs in millisecond pulsars, analysing 12 sources observed with the Large European Array for Pulsars (LEAP), and the Effelsberg 1…

Radio timing constraints on the mass of the binary pulsar PSR J1528-3146

A. Berthereau, L. Guillemot, P. C. C. Freire +7

PSR J1528-3146 is a 60.8 ms pulsar orbiting a heavy white dwarf (WD) companion, with an orbital period of 3.18 d. This work aimed at characterizing the pulsar's astrometric, spin a…

A new pulsar timing model for scalar-tensor gravity with applications to PSR J2222-0137 and pulsar-black hole binaries

A. Batrakov, H. Hu, N. Wex +8

Context. Scalar-tensor gravity (STG) theories are well-motivated alternatives to general relativity (GR). One class of STG theories, the Damour-Esposito-Farese (DEF) gravity, has a…

Pulsar Scintillation Studies with LOFAR: II. Dual-frequency scattering study of PSR J0826+2637 with LOFAR and NenuFAR

Ziwei Wu, William A. Coles, Joris P. W. Verbiest +28

Interstellar scattering (ISS) of radio pulsar emission can be used as a probe of the ionised interstellar medium (IISM) and causes corruptions in pulsar timing experiments. Two typ…

Neutron star mass estimates from gamma-ray eclipses in spider millisecond pulsar binaries

C. J. Clark, M. Kerr, E. D. Barr +26

Reliable neutron star mass measurements are key to determining the equation-of-state of cold nuclear matter, but these are rare. "Black Widows" and "Redbacks" are compact binaries…
