Search for Extended GeV Sources in the Inner Galactic Plane
S. Abdollahi, F. Acero, A. Acharyya +108
The recent detection of extended -ray emission around middle-aged pulsars is interpreted as inverse-Compton scattering of ambient photons by electron-positron pairs escaping the…
Explanation of the exceptionally strong timing noise of PSR J0337+1715 by a circum-ternary planet and consequences for gravity tests
Guillaume Voisin, Ismaël Cognard, Melaine Saillenfest +6
Context: Timing of pulsar PSR J0337+1715 provides a unique opportunity to test the strong equivalence principle (SEP) with a strongly self-gravitating object. This is due to its un…
Pulsar timing methods for evaluating dispersion measure time series
F. Iraci, A. Chalumeau, C. Tiburzi +9
Radio pulsars allow the study of the ionised interstellar medium and its dispersive effects, a major noise source in gravitational wave searches using pulsars. In this paper, we co…
Impact of the observation frequency coverage on the significance of a gravitational wave background detection in PTA data
Irene Ferranti, Mikel Falxa, Alberto Sesana +8
Pulsar Timing Array (PTA) collaborations gather high-precision timing measurements of pulsars with the aim of detecting gravitational wave (GW) signals. A major challenge lies in t…
Exploring the time variability of the Solar Wind using LOFAR pulsar data
S. C. Susarla, A. Chalumeau, C. Tiburzi +22
High-precision pulsar timing is highly dependent on precise and accurate modeling of any effects that impact the data. It was shown that commonly used Solar Wind models do not accu…
Triple trouble with PSR J1618-3921: Mass measurements and orbital dynamics of an eccentric millisecond pulsar
K. Grunthal, V. Venkatraman Krishnan, P. C. C. Freire +11
PSR J1618-3921 is one of five known millisecond pulsars (MSPs) in eccentric orbits (eMPSs) located in the Galactic plane, whose formation is poorly understood. Earlier studies of t…
