Revisiting profile instability of J1022+1001
Prajwal V. Padmanabh, Ewan D. Barr, David J. Champion +4
Millisecond pulsars in timing arrays can act as probes for gravitational wave detection and improving the solar system ephemerides among several other applications. However, the st…
Pulsar Candidate Identification Using Semi-Supervised Generative Adversarial Networks
Vishnu Balakrishnan, David Champion, Ewan Barr +3
Machine learning methods are increasingly helping astronomers identify new radio pulsars. However, they require a large amount of labelled data, which is time consuming to produce…
A precise mass measurement of PSR J2045+3633
J. W. McKee, P. C. C. Freire, M. Berezina +10
We present the results of a timing analysis undertaken with the goal of obtaining an improved mass measurement of the recycled pulsar J2045+3633. Using regular high-cadence observa…
High-cadence observations and variable spin behaviour of magnetar Swift J1818.0-1607 after its outburst
David Champion, Ismael Cognard, Marilyn Cruces +17
We report on multi-frequency radio observations of the new magnetar Swift J1818.0-1607, following it for more than one month with high cadence. The observations commenced less than…
Constraining the dense matter equation-of-state with radio pulsars
Huanchen Hu, Michael Kramer, Norbert Wex +2
Radio pulsars provide some of the most important constraints for our understanding of matter at supranuclear densities. So far, these constraints are mostly given by precision mass…
Precise mass measurements for the double neutron star system J1829+2456
Henryk T. Haniewicz, Robert D. Ferdman, Paulo C. C. Freire +4
PSR J1829+2456 is a radio pulsar in a relativistic binary system with another neutron star. It has a rotational period of 41 ms and a mildly eccentric () 28-hr orbit. We…
