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…
Fifteen new millisecond pulsars in 47 Tucanae
W. Chen, D. Risbud, P. C. C. Freire +16
47 Tucanae is one of the largest, brightest, and closest globular clusters to Earth. It hosts an exotic stellar population with stellar dynamics that indicate a complex evolution h…
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…
Detection of Cyclotron Absorption in the Radio Emission of GPM 1839-10
Yunpeng Men, Ewan Barr, Yuanhong Qu +8
GPM 1839-10 is an intriguing long-period radio transient (LPT), distinguished by its activity spanning at least three decades and its highly unusual emission characteristics. These…
A survey for radio pulsars and transients in the 10 pc region around Sgr A*
G. Desvignes, R. P. Eatough, Y. Men +7
Here we report on a new survey for pulsars and transients in the 10 pc region around Sgr A* using the Effelsberg radio telescope at frequencies between 4 to 8 GHz. Our calibrated f…
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 highly magnetized long-period radio transient exhibiting unusual emission features
Yunpeng Men, Sam McSweeney, Natasha Hurley-Walker +2
Long-period radio transients are a new class of astrophysical objects that exhibit periodic radio emission on timescales of tens of minutes. Their true nature remains unknown; poss…
An emission state switching radio transient with a 54 minute period
M. Caleb, E. Lenc, D. L. Kaplan +19
Long-period radio transients are an emerging class of extreme astrophysical events of which only three are known. These objects emit highly polarised, coherent pulses of typically…
The TRAPUM Small Magellanic Cloud pulsar survey with MeerKAT: I. Discovery of seven new pulsars and two Pulsar Wind Nebula associations
E. Carli, L. Levin, B. W. Stappers +17
The sensitivity of the MeerKAT radio interferometer is an opportunity to probe deeper into the population of rare and faint extragalactic pulsars. The TRAPUM (TRAnsients and PUlsar…
TRAPUM search for pulsars in supernova remnants and pulsar wind nebulae -- I. Survey description and initial discoveries
J. D. Turner, B. W. Stappers, E. Carli +18
We present the description and initial results of the TRAPUM (TRAnsients And PUlsars with MeerKAT) search for pulsars associated with supernova remnants (SNRs), pulsar wind nebulae…
TransientX: A high performance single pulse search package
Yunpeng Men, Ewan Barr
Radio interferometers composed of a large array of small antennas posses large fields of view, coupled with high sensitivities. For example, the Karoo Array Telescope (MeerKAT), ac…
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)…
PulsarX: a new pulsar searching package -I. A high performance folding program for pulsar surveys
Yunpeng Men, Ewan Barr, C. J. Clark +2
Pulsar surveys with modern radio telescopes are becoming increasingly computationally demanding. This is particularly true for wide field-of-view pulsar surveys with radio interfer…
The MPIfR-MeerKAT Galactic Plane survey I -- System setup and early results
P. V. Padmanabh, E. D. Barr, S. S. Sridhar +30
Galactic plane radio surveys play a key role in improving our understanding of a wide range of astrophysical phenomena. Performing such a survey using the latest interferometric te…
MeerKAT discovery of 13 new pulsars in Omega Centauri
W. Chen, P. C. C. Freire, A. Ridolfi +21
The most massive globular cluster in our Galaxy, Omega Centauri, is an interesting target for pulsar searches, because of its multiple stellar populations and the intriguing possib…
A fast radio burst source at a complex magnetised site in a barred galaxy
H. Xu, J. R. Niu, P. Chen +71
Fast radio bursts (FRBs) are highly dispersed millisecond-duration radio bursts. Recent observations of a Galactic FRB suggest that at least some FRBs originate from magnetars, but…
