Wideband timing of the Parkes Pulsar Timing Array UWL data
Małgorzata Curyło, Timothy T. Pennucci, Matthew Bailes +14
In 2018 an ultra-wide-bandwidth low-frequency (UWL) receiver was installed on the 64-m Parkes Radio Telescope enabling observations with an instantaneous frequency coverage from 70…
An unusual pulse shape change event in PSR J1713+0747 observed with the Green Bank Telescope and CHIME
Ross J. Jennings, James M. Cordes, Shami Chatterjee +41
The millisecond pulsar J1713+0747 underwent a sudden and significant pulse shape change between April 16 and 17, 2021 (MJDs 59320 and 59321). Subsequently, the pulse shape graduall…
Gravitational signal propagation in the Double Pulsar studied with the MeerKAT telescope
H. Hu, M. Kramer, D. J. Champion +16
The Double Pulsar, PSR J0737-3039A/B, has offered a wealth of gravitational experiments in the strong-field regime, all of which GR has passed with flying colours. In particular, a…
The International Pulsar Timing Array second data release: Search for an isotropic Gravitational Wave Background
J. Antoniadis, Z. Arzoumanian, S. Babak +123
We searched for an isotropic stochastic gravitational wave background in the second data release of the International Pulsar Timing Array, a global collaboration synthesizing decad…
Wide-band timing of GMRT discovered millisecond pulsars
Shyam S. Sharma, Jayanta Roy, Bhaswati Bhattacharyya +6
Modeling of frequency-dependent effects, contributed by the turbulence in the free electron density of interstellar plasma, is required to enable the detection of the expected impr…
