Nanohertz Gravitational-Wave Constraints on Supermassive Binary Black Holes at Cosmic Dawn

Yiqin Chen, Shi-Yi Zhao, Xingjiang Zhu +16

Standard continuous gravitational-wave searches with pulsar timing arrays (PTAs) neglect cosmological redshift, restricting their applicability to the local Universe. We introduce…

Targeted search for eccentric supermassive binary black holes in OJ 287 and nearby galaxy clusters with PPTA DR3

Shi-Yi Zhao, Xingjiang Zhu, Jacob Cardinal Tremblay +19

We perform Bayesian targeted searches for continuous gravitational waves from eccentric supermassive binary black holes (SMBBHs) using the Parkes Pulsar Timing Array third data rel…

Search for Gravitational Wave Memory in PPTA and EPTA Data: A Complete Signal Model

Sharon Mary Tomson, Boris Goncharov, Rutger van Haasteren +21

We perform searches for gravitational wave memory in the data of two major Pulsar Timing Array (PTA) experiments located in Europe and Australia. Supermassive black hole binaries (…

Frequency- and phase-resolved polarimetry of millisecond pulsars and its application to timing

Małgorzata Curyło, Andrew Zic, Shuangqiang Wang +16

Pulsar timing is used for a variety of applications including tests of fundamental physics, probing the structure of neutron stars, and detecting nanohertz gravitational waves. Dev…

A glitch in the millisecond pulsar J09003144

Bhavnesh Bhat, Michael J. Keith, Ismaël Cognard +11

We report the detection of a glitch in the millisecond pulsar (MSP) PSR J09003144, which is included in the European, MeerKAT and Parkes pulsar timing array experiments. The dat…
