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…
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…
Variability of Sagittarius A* at 3 GHz on minute-scale with MeerKAT
K. Kaur, I. Rammala-Zitha, A. Basu +21
The supermassive black hole Sagittarius A* (Sgr A*) exhibits temporal and spectral variability across the electromagnetic spectrum. However, variability at radio frequencies below…
Long-term timing of the relativistic binary PSR J1906+0746
L. Vleeschower, B. W. Stappers, M. J. Keith +9
We conducted a timing analysis of over 18 years of data on the young ( kyr, \,ms) relativistic binary PSR~J1906+0746, using six radio telescopes: Arecibo…
