The EDD Radio Astronomy Backend Framework
Ewan D. Barr, Amit Bansod, Jan Behrend +16
Modern digital radio astronomy receivers produce increasingly wide-bandwidth, high bit-rate data streams that necessitate the development of flexible, scalable, and maintainable ba…
The first MeerKAT S-band globular cluster pulsar survey
Rouhin Nag, Marta Burgay, Alessandro Ridolfi +19
Globular clusters are efficient factories of recycled pulsars, but searches toward high-dispersion-measure (DM) clusters can be strongly limited near 1 GHz by dispersive smearing a…
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…
An RFSoC-based F-engine for ARGOS
Yunpeng Men, Ewan Barr, Amit Bansod +8
Radio interferometers provide the means to perform the wide-field-of-view (FoV), high-sensitivity observations required for modern radio surveys. As computing power per cost has de…
A pulsar in a binary with a compact object in the mass gap between neutron stars and black holes
Ewan D. Barr, Arunima Dutta, Paulo C. C. Freire +22
Among the compact objects observed in gravitational wave merger events a few have masses in the gap between the most massive neutron stars (NSs) and least massive black holes (BHs)…
FRB 20210405I: a nearby Fast Radio Burst localised to sub-arcsecond precision with MeerKAT
Laura Nicole Driessen, Ewan Barr, David Buckley +19
We present the first sub-arcsecond localised Fast Radio Burst (FRB) detected using MeerKAT. FRB 20210405I was detected in the incoherent beam using the MeerTRAP pipeline on 2021 Ap…
Missing for 20 years: MeerKAT re-detects the elusive binary pulsar M30B
Vishnu Balakrishnan, Paulo Freire, Scott Ransom +14
PSR J21402311B is a 13-ms pulsar discovered in 2001 in a 7.8-hour Green Bank Telescope (GBT) observation of the core-collapsed globular cluster M30 and predicted to be in a high…
Radio detection of an elusive millisecond pulsar in the Globular Cluster NGC 6397
Lei Zhang, Alessandro Ridolfi, Harsha Blumer +32
We report the discovery of a new 5.78 ms-period millisecond pulsar (MSP), PSR J1740-5340B (NGC 6397B), in an eclipsing binary system discovered with the Parkes radio telescope (now…
Discovery of a radio emitting neutron star with an ultra-long spin period of 76 seconds
Manisha Caleb, Ian Heywood, Kaustubh Rajwade +19
The radio-emitting neutron star population encompasses objects with spin periods ranging from milliseconds to tens of seconds. As they age and spin more slowly, their radio emissio…
Wide field beamformed observation with MeerKAT
Weiwei Chen, Ewan Barr, Ramesh Karuppusamy +2
Large-scale beamforming with radio interferometers has the potential to revolutionize the science done with pulsars and fast radio bursts by improving the survey efficiency for the…
