Interplanetary scintillation-informed heliospheric modelling for the MeerKAT Pulsar Timing Array 4.5 yr dataset
Saurav Mishra, Daniel J. Reardon, Andrew Zic +9
Heliospheric density variations impart delays on pulse times of arrivals from millisecond pulsars. Improper modelling of these variations may affect gravitational wave detection an…
A search for Fast Radio Bursts from globular clusters in M49 with FAST
Simon C. -C. Ho, Chris Flynn, Matthew Bailes +7
The origins of fast radio bursts (FRBs) remain uncertain, although magnetars are a leading progenitor candidate. Because magnetars are thought to form primarily through core-collap…
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…
The Thousand-Pulsar-Array programme on MeerKAT XIX: Single-pulse data analysis, nulling and pulse energy distributions
Michael J. Keith, Patrick Weltevrede, Lucy Oswald +8
We present the Thousand Pulsar Array (TPA) single-pulse data set, obtained with the MeerKAT radio telescope and comprising time-series observations of 1192 pulsars, typically conta…
Pulsed radio emission from a Central Compact Object
Lei Zhang, Alessandro Ridolfi, Di Li +7
Located at the centres of supernova remnants, central compact objects (CCOs) are among the most puzzling neutron stars. CCOs are bright in thermal X-rays, yet have evaded detection…
A joint MeerKAT and Parkes view of Omega Centauri: New TRAPUM Searches and Pulsar Timing
Miquel Colom i Bernadich, Shi Dai, Federico Abbate +27
Millisecond pulsars (MSPs) are powerful probes of globular clusters (GCs), tracing stellar evolution, cluster dynamics, and the local gravitational potential. We investigate the MS…
