Detection of relativistic orbital deformation from improved timing of PSR J17571854
Jaikhomba Singha, Vivek Venkatraman Krishnan, Marisa Geyer +12
PSR~J17571854, a 21.5\,ms pulsar, is a highly relativistic double neutron star (DNS) system in a tight eccentric () 4.4\,hr orbit. With extremely large gravitational w…
Improved proper motion and gravity tests with PSR J1913+1102
Xueli Miao, Paulo C. C. Freire, Norbert Wex +11
PSR J1913+1102 is a highly asymmetric double neutron star system and an excellent laboratory for testing scalar-tensor gravity theories, as well as a potential progenitor analogue…
Optimising gravitational-wave sky maps for pulsar timing arrays
Kathrin Grunthal, David J. Champion, Eric Thrane +3
Pulsar timing arrays (PTAs) have recently reported compelling evidence for the presence of a gravitational-wave background signal. Mapping the gravitational-wave background is key…
The role of distant pulsars in the detectability of continuous gravitational waves
Kathrin Grunthal, Nataliya Porayko, David J. Champion +1
One of the imminent science goals of pulsar timing arrays (PTAs) is the detection of a continuous gravitational wave (CGW) emitted by an individual supermassive black hole binary (…
The double neutron star PSR J1946+2052 I. Masses and tests of general relativity
Lingqi Meng, Paulo C. C. Freire, Kevin Stovall +28
We conducted high-precision timing of PSR J1946+2052 to determine the masses of the two neutron stars in the system, test general relativity (GR) and assessed the system's potentia…
Optimising the MeerKAT Pulsar Timing Array and towards precision pulsar timing with SKA-mid
Pratyasha Gitika, Ryan M. Shannon, Matthew Bailes +4
Pulsar timing arrays (PTAs) are Galactic-scale nanohertz-frequency gravitational wave (GW) detectors. Recently, several PTAs have found evidence for the presence of GWs in their da…
