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…
Coherent Search for Binary Pulsars across all Five Keplerian Parameters in Radio Observations using the template-bank algorithm
Vishnu Balakrishnan, David Champion, Ewan Barr +5
Relativistic binary pulsars orbiting white dwarfs and neutron stars have already provided excellent tests of gravity. However, despite observational efforts, a pulsar orbiting a bl…
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…
MeerTRAP in the era of multi-messenger astrophysics
Kaustubh Rajwade, Benjamin Stappers, Christopher Williams +9
Real-time detections of transients and rapid multi-wavelength follow-up are at the core of modern multi-messenger astrophysics. MeerTRAP is one such instrument that has been deploy…
Real-time triggering capabilities for Fast Radio Bursts at the MeerKAT telescope
F. Jankowski, M. Berezina, B. W. Stappers +9
Fast Radio Bursts (FRBs) are bright enigmatic radio pulses of roughly millisecond duration that come from extragalactic distances. As part of the MeerTRAP project, we use the MeerK…
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…
The MeerKAT Telescope as a Pulsar Facility: System verification and early science results from MeerTime
M. Bailes, A. Jameson, F. Abbate +72
We describe system verification tests and early science results from the pulsar processor (PTUSE) developed for the newly-commissioned 64-dish SARAO MeerKAT radio telescope in Sout…
Optimal periodicity searching: Revisiting the Fast Folding Algorithm for large-scale pulsar surveys
V. Morello, E. D. Barr, B. W. Stappers +2
The Fast Folding Algorithm (FFA) is a phase-coherent search technique for periodic signals. It has rarely been used in radio pulsar searches, having been historically supplanted by…
The UTMOST Survey for Magnetars, Intermittent pulsars, RRATs and FRBs I: System description and overview
V. Venkatraman Krishnan, C. Flynn, W. Farah +22
We describe the ongoing `Survey for Magnetars, Intermittent pulsars, Rotating radio transients and Fast radio bursts' (SMIRF), performed using the newly refurbished UTMOST telescop…
The High Time Resolution Universe survey XIV: Discovery of 23 pulsars through GPU-accelerated reprocessing
V. Morello, E. D. Barr, S. Cooper +21
We have performed a new search for radio pulsars in archival data of the intermediate and high Galactic latitude parts of the Southern High Time Resolution Universe pulsar survey.…
MeerTime - the MeerKAT Key Science Program on Pulsar Timing
M. Bailes, E. Barr, N. D. R. Bhat +28
The MeerKAT telescope represents an outstanding opportunity for radio pulsar timing science with its unique combination of a large collecting area and aperture efficiency (effectiv…
Pulsar Searches with the SKA
L. Levin, W. Armour, C. Baffa +24
The Square Kilometre Array will be an amazing instrument for pulsar astronomy. While the full SKA will be sensitive enough to detect all pulsars in the Galaxy visible from Earth, a…
The UTMOST: A hybrid digital signal processor transforms the MOST
M. Bailes, A. Jameson, C. Flynn +20
The Molonglo Observatory Synthesis Telescope (MOST) is an 18,000 square meter radio telescope situated some 40 km from the city of Canberra, Australia. Its operating band (820-850…
