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…

Magneto-Active Environments in Pulsar Binaries with the MeerKAT Telescope: I. Pulsar sample and their basic properties

Jaikhomba Singha, Dongzi Li, Marisa Geyer +6

Eclipsing pulsar binaries and binaries with a high mass companion are ideal systems for studying and understanding the properties of plasma in magneto-ionic environments. In this w…

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…

Timing and noise analysis of five millisecond pulsars observed with MeerKAT

M. Chisabi, S. Andrianomena, U. Enwelum +12

Millisecond pulsars (MSPs) in binary systems are precise laboratories for tests of gravity and the physics of dense matter. Their orbits can show relativistic effects that provide…

Mining the time axis with TRON. I. Millisecond pulsars in Omega Centauri, Terzan 5 and 47 Tucanae detected through MeerKAT interferometric imaging

Oleg M. Smirnov, Ian Heywood, Marisa Geyer +13

Medium-timescale (minutes to hours) radio transients are a relatively unexplored population. The wide field-of-view and high instantaneous sensitivity of instruments such as MeerKA…
