Discovery of Millisecond Pulsars in the Globular Cluster Omega Centauri
Shi Dai, Simon Johnston, Matthew Kerr +4
The globular cluster Omega Centauri is the most massive and luminous cluster in the Galaxy. The -ray source FL8Y J1326.74729 is coincident with the core of the cluster, leadi…
Probing the emission states of PSR J1107-5907
Jingbo Wang, George Hobbs, Matthew Kerr +14
The emission from PSR J1107-5907 is erratic. Sometimes the radio pulse is undetectable, at other times the pulsed emission is weak, and for short durations the emission can be very…
An ultra-wide bandwidth (704 to 4032 MHz) receiver for the Parkes radio telescope
G. Hobbs, R. N. Manchester, A. Dunning +69
We describe an ultra-wide-bandwidth, low-frequency receiver ("UWL") recently installed on the Parkes radio telescope. The receiver system provides continuous frequency coverage fro…
Wide Bandwidth Observations of Pulsars C, D and J in 47 Tucanae
Lei Zhang, George Hobbs, Richard N. Manchester +13
We report the first wideband observations of pulsars C, D and J in the globular cluster 47Tucanae (NGC 104) using the Ultra-Wideband Low (UWL) receiver system recently installed on…
Serendipitous Discovery of PSR J1431-6328 as a Highly-Polarized Point Source with the Australian SKA Pathfinder
David Kaplan, Shi Dai, Emil Lenc +10
We identified a highly-polarized, steep-spectrum radio source in a deep image with the Australian Square Kilometre Array Pathfinder (ASKAP) telescope at 888 MHz. After considering…
The Radiation Structure of PSR B201628 Observed with FAST
Jiguang Lu, Bo Peng, Renxin Xu +8
With the largest dish Five-hundred-meter Aperture Spherical radio Telescope (FAST), both the mean and single pulses of PSR B201628, especially including the single-pulse structu…
