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…
Fifteen new millisecond pulsars in 47 Tucanae
W. Chen, D. Risbud, P. C. C. Freire +16
47 Tucanae is one of the largest, brightest, and closest globular clusters to Earth. It hosts an exotic stellar population with stellar dynamics that indicate a complex evolution h…
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…
Radio timing constraints on the orbital orientation and component masses of PSR J14553330
D. S. Pillay, V. Venkatraman Krishnan, David J. Champion +15
PSR J14553330 is a 7.98 ms pulsar in a 76.17 day nearly circular orbit with a white dwarf companion. In this work, we combine the available Lovell, Nançay decimetri…
Scintillating insights into PSR~J07373039A and the interstellar plasma of the Gum Nebula from MeerKAT
J. Askew, D. J. Reardon, R. M. Shannon +8
The double pulsar system PSR~J07373039A/B has enabled some of the most precise tests of strong-field gravity to date. Here, we present a scintillation analysis of the system bas…
NGC 1851A: Revealing an ongoing three-body encounter in a dense globular cluster
A. Dutta, P. C. C. Freire, T. Gautam +16
PSR J05144002A is a binary millisecond pulsar located in the globular cluster NGC 1851. The pulsar has a spin period of 4.99 ms, an orbital period of 18.8 days, and is in a very…
