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…

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…
