On the triple nature of the PSR J0435+3233 system
Paulo C. C. Freire, Colin J. Clark, Cees G. Bassa +4
The paper presents evidence that the millisecond pulsar PSR J0435+3233 is part of a hierarchical triple system, with a wide-orbit tertiary star causing apparent variations in its s…
Pulsars in Globular Clusters With the SKAO
M. Bagchi, F. Abbate, V. Balakrishnan +14
Globular clusters (GCs) are highly efficient factories of radio pulsars: per unit of stellar mass, they contain about 1000 times more pulsars than in the Galactic field. Thus far,…
Testing Gravity with Binary Pulsars in the SKA Era
V. Venkatraman Krishnan, L. Shao, V. Balakrishnan +21
Binary (and trinary) radio pulsars are natural laboratories in space for understanding gravity in the strong field regime, with many unique and precise tests carried out so far, in…
Probing Neutron Star Interiors and the Properties of Cold Ultra-dense Matter with the SKAO
Avishek Basu, Vanessa Graber, Marcus E. Lower +19
Matter inside neutron stars is compressed to densities several times greater than nuclear saturation density, while maintaining low temperatures and large asymmetries between neutr…
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…
