The MSPSR catalogue: VLBA astrometry of 18 millisecond pulsars
H. Ding, A. T. Deller, B. W. Stappers +13
With unparalleled rotational stability, millisecond pulsars (MSPs) serve as ideal laboratories for numerous astrophysical studies, many of which require precise knowledge of the di…
The SPAN512 mid-latitude pulsar survey at the Nançay Radio Telescope
Gregory Desvignes, Ismael Cognard, David A. Smith +6
The large number of ongoing surveys for pulsars and transients at various radio observatories is motivated by the science obtained from these sources. Timing and polarisation analy…
One pulsar, two white dwarfs, and a planet confirming the strong equivalence principle
Guillaume Voisin, G Luth, I Cognard +7
The strong equivalence principle is a cornerstone of general relativity, tested with exquisite accuracy in the Solar system. However, tests in the strong-field regime require a com…
Robust parameter estimation from pulsar timing data
A. Samajdar, G. Shaifullah, A. Sesana +8
Recently, global pulsar timing arrays have released results from searching for a nano-Hertz gravitational wave background signal. Although there has not been any definite evidence…
Long-term scintillation studies of EPTA pulsars. I. Observations and basic results
Yulan Liu, Joris P. W. Verbiest, Robert A. Main +17
Interstellar scintillation analysis of pulsars allows us to probe the small-scale distribution and inhomogeneities of the ionized interstellar medium. Our priority is to present th…
A Gamma-ray Pulsar Timing Array Constrains the Nanohertz Gravitational Wave Background
M. Ajello, W. B. Atwood, L. Baldini +129
After large galaxies merge, their central supermassive black holes are expected to form binary systems whose orbital motion generates a gravitational wave background (GWB) at nanoh…
Irradiated but not eclipsed, the case of PSR J0610-2100
E. van der Wateren, C. G. Bassa, C. J. Clark +7
We report on radio timing observations of the black widow binary pulsar J06102100 and optical observations of its binary companion. The radio timing observations extend the timi…
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…
