The Parkes Observatory Pulsar Data Archive
Lawrence Toomey, George Hobbs, James Dempsey +3
Data from observations of pulsars made by Murriyang, the CSIRO Parkes 64-metre radio-telescope over the last three decades are more accessible than ever before, largely due to thei…
GASKAP-HI Pilot Survey Science III: An unbiased view of cold gas in the Small Magellanic Cloud
James Dempsey, N. M. McClure-Griffiths, Claire Murray +14
We present the first unbiased survey of neutral hydrogen (HI) absorption in the Small Magellanic Cloud (SMC). The survey utilises pilot HI observations with the Australian Square K…
Cold HI ejected into the Magellanic Stream
J. Dempsey, N. M. McClure-Griffiths, K. Jameson +1
We report the direct detection of cold HI gas in a cloud ejected from the Small Magellanic Cloud (SMC) towards the Magellanic Stream. The cloud is part of a fragmented shell of HI…
Parkes transient events: I. Database of single pulses, initial results and missing FRBs
S. -B. Zhang, G. Hobbs, C. J. Russell +16
A large number of observations from the Parkes 64\,m-diameter radio telescope, recorded with high time resolution, are publicly available. We have re-processed all of the observati…
The Parkes Pulsar Timing Array Project: Second data release
M. Kerr, D. J. Reardon, G. Hobbs +27
We describe 14 years of public data from the Parkes Pulsar Timing Array (PPTA), an ongoing project that is producing precise measurements of pulse times of arrival from 26 millisec…
The HI/OH/Recombination line survey of the inner Milky Way (THOR): data release 2 and HI overview
Y. Wang, H. Beuther, M. R. Rugel +17
With the Very Large Array (VLA) in C-configuration, we observed a large portion of the first Galactic quadrant ( and $\lvert b \rvert \leq 1.25…
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…
An ATCA Survey of HI Absorption in the Magellanic Clouds I: HI Gas Temperature Measurements in the Small Magellanic Cloud
Katherine Jameson, Naomi McClure-Griffiths, Boyang Liu +9
We present the first results from the Small Magellanic Cloud portion of a new Australia Telescope Compact Array (ATCA) HI absorption survey of both of the Magellanic Clouds, compri…
Commensal discovery of four Fast Radio Bursts during Parkes Pulsar Timing Array observations
S. Osłowski, R. M. Shannon, V. Ravi +25
The Parkes Pulsar Timing Array (PPTA) project monitors two dozen millisecond pulsars (MSPs) in order to undertake a variety of fundamental physics experiments using the Parkes 64m…
Parkes Pulsar Timing Array constraints on ultralight scalar-field dark matter
Nataliya K. Porayko, Xingjiang Zhu, Yuri Levin +27
It is widely accepted that dark matter contributes about a quarter of the critical mass-energy density in our Universe. The nature of dark matter is currently unknown, with the mas…
Comparison of Pulsar Positions from Timing and Very Long Baseline Astrometry
J. B. Wang, W. A. Coles, G. Hobbs +22
Pulsar positions can be measured with high precision using both pulsar timing methods and very-long-baseline interferometry (VLBI). Pulsar timing positions are referenced to a sola…
Wide-band Profile Domain Pulsar Timing Analysis
L. Lentati, M. Kerr, S. Dai +22
We extend profile domain pulsar timing to incorporate wide-band effects such as frequency-dependent profile evolution and broadband shape variation in the pulse profile. We also in…
The disturbance of a millisecond pulsar magnetosphere
R. M. Shannon, L. T. Lentati, M. Kerr +21
Pulsar timing has enabled some of the strongest tests of fundamental physics. Central to the technique is the assumption that the detected radio pulses can be used to accurately me…
Gravitational-wave cosmology across 29 decades in frequency
Paul D. Lasky, Chiara M. F. Mingarelli, Tristan L. Smith +24
Quantum fluctuations of the gravitational field in the early Universe, amplified by inflation, produce a primordial gravitational-wave background across a broad frequency band. We…
Versatile Directional Searches for Gravitational Waves with Pulsar Timing Arrays
D. R. Madison, X. -J. Zhu, G. Hobbs +23
By regularly monitoring the most stable millisecond pulsars over many years, pulsar timing arrays (PTAs) are positioned to detect and study correlations in the timing behaviour of…
Using the Parkes Pulsar Data Archive
J. Khoo, G. Hobbs, R. N. Manchester +2
The Parkes Pulsar Data Archive currently provides access to 165,755 data files obtained from observations carried out at the Parkes Observatory since the year 1991. Data files and…
The Parkes Observatory Pulsar Data Archive
G. Hobbs, D. Miller, R. N. Manchester +39
The Parkes pulsar data archive currently provides access to 144044 data files obtained from observations carried out at the Parkes observatory since the year 1991. Around 10^5 file…
