Discovery of 51 pulsars in a reanalysis of the Green Bank North Celestial Cap Survey and a revised pulsar census
R. Sengar, L. Vleeschower, D. L. Kaplan +13
We present results from a reanalysis of the Green Bank North Celestial Cap (GBNCC) survey, conducted at 350 MHz with the Green Bank Telescope between 2009 and 2020, covering the sk…
Radio and Gamma-Ray Timing of a Newly Discovered Millisecond Pulsar
L. Vleeschower, R. Sengar, L. Nieder +17
We report the discovery and timing of PSR J2147-3604, a fully recycled millisecond pulsar with a spin period of 3.2 ms, discovered in a reprocessing of the 350-MHz Green Bank North…
A Candidate Open Cluster Pulsar: Timing Analysis of PSR J1922+3745 in NGC 6791
Xiao-Jin Liu, Ralph P. Eatough, Zhichen Pan +15
PSR J1922+3745 was recently identified as a radio pulsar toward the old open cluster NGC 6791, raising the prospect of the first pulsar associated with an open cluster. We report F…
Discovery of a 36-minute long-period transient ASKAP J142431.2-612611
Joshua Pritchard, Tara Murphy, Dougal Dobie +13
We report the discovery of a new long-period radio transient, ASKAP J142431.2-612611, with a 36 minute period, identified in the Australian SKA Pathfinder Evolutionary Map of the U…
Discovery of Millisecond Pulsars toward the Galactic Bulge in an Image-based Survey with MeerKAT
Rahul Sengar, Akash Anumarlapudi, David L. Kaplan +3
We report on the follow-up observations of circularly polarized sources identified in the MeerKAT image-based survey of the Galactic bulge. Using the Parkes radio telescope, we obs…
Discovery of Two Highly Scattered Pulsars from Image-Based Circular Polarization Searches with the Australian SKA Pathfinder
Rahul Sengar, David L. Kaplan, Emil Lenc +6
We report the discovery and timing of two pulsars from a sample of four circularly polarized sources identified in radio continuum images taken as part of the Australian SKA Pathfi…
The High Time Resolution Universe Pulsar Survey-XIX. A coherent GPU accelerated reprocessing and the discovery of 71 pulsars in the Southern Galactic plane
R. Sengar, M. Bailes, V. Balakrishnan +19
We have conducted a GPU accelerated reprocessing of of the archival data from the High Time Resolution Universe South Low Latitude (HTRU-S LowLat) pulsar survey by impl…
PSR J1922+37: a 1.9-second pulsar discovered in the direction of the old open cluster NGC 6791
Xiao-Jin Liu, Rahul Sengar, Matthew Bailes +8
More than 300 pulsars have been discovered in Galactic globular clusters; however, none have been found in open clusters. Here we present results from 20-hour pulsar searching obse…
Eighteen new fast radio bursts in the High Time Resolution Universe survey
M. Trudu, A. Possenti, M. Pilia +16
Current observational evidence reveals that fast radio bursts (FRBs) exhibit bandwidths ranging from a few dozen MHz to several GHz. Traditional FRB searches primarily employ match…
An Image-Based Search for Pulsar Candidates in the MeerKAT Bulge Survey
Dale A. Frail, Emil Polisensky, Scott D. Hyman +13
We report on the results of an image-based search for pulsar candidates toward the Galactic bulge. We used mosaic images from the MeerKAT radio telescope, that were taken as part o…
Discovery of radio eclipses from 4FGL J1646.54406: a new candidate redback pulsar binary
Andrew Zic, Ziteng Wang, Emil Lenc +9
Large widefield surveys make possible the serendipitous discovery of rare sub-classes of pulsars. One such class are "spider"-type pulsar binaries, comprised of a pulsar in a compa…
Discovery of a young, highly scattered pulsar PSR J1032-5804 with the Australian SKA Pathfinder
Ziteng Wang, David L. Kaplan, Rahul Sengar +7
We report the discovery of a young, highly scattered pulsar in a search for highly circularly polarized radio sources as part of the Australian Square Kilometre Array Pathfinder (A…
The High Time Resolution Universe Pulsar Survey -- XVIII. The reprocessing of the HTRU-S Low Lat survey around the Galactic centre using a Fast Folding Algorithm pipeline for accelerated pulsars
J. Wongphechauxsorn, D. J. Champion, M. Bailes +18
The HTRU-S Low Latitude survey data within 1of the Galactic Centre (GC) were searched for pulsars using the Fast Folding Algorithm (FFA). Unlike traditional Fast Fourier…
