The first MeerKAT S-band globular cluster pulsar survey
Rouhin Nag, Marta Burgay, Alessandro Ridolfi +19
Globular clusters are efficient factories of recycled pulsars, but searches toward high-dispersion-measure (DM) clusters can be strongly limited near 1 GHz by dispersive smearing a…
Sub-Millisecond Pulsars: Missing or Impossible?
T. M. Tauris, V. Venkatraman Krishnan, R. Senzel +7
The minimum spin period attainable by a neutron star has been debated since the discovery of the first millisecond pulsar in 1982. A neutron star rotating faster than 1 ms would ha…
On the triple nature of the PSR J0435+3233 system
Paulo C. C. Freire, Colin J. Clark, Cees G. Bassa +4
The recent pulsar timing ephemeris of PSR J0435+3233 indicates that this millisecond pulsar (MSP) has a spin-down rate that is much higher than observed in other MSPs and challenge…
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…
Discovery of a 24-millisecond pulsar in a very long orbit with the Murchison Widefield Array
Chia Min Tan, N. D. Ramesh Bhat, Bradley W. Meyers +9
We report the discovery of PSR J01255854, a pulsar with a spin period of 24 ms and a dispersion measure of 11.66 pc cm in the ongoing Southern-sky MWA Rapid Two-metre (SMAR…
Constraints on Einstein-aether gravity from the precision timing of PSR J1738+0333
Massimo Vaglio, Amodio Carleo, Abhimanyu Susobhanan +5
We constrain Einstein-aether gravity -- a Lorentz-violating extension of General Relativity in which a dynamical, unit timelike vector field selects a preferred frame -- using upda…
A joint MeerKAT and Parkes view of Omega Centauri: New TRAPUM Searches and Pulsar Timing
Miquel Colom i Bernadich, Shi Dai, Federico Abbate +27
Millisecond pulsars (MSPs) are powerful probes of globular clusters (GCs), tracing stellar evolution, cluster dynamics, and the local gravitational potential. We investigate the MS…
