A long-period radio transient active for three decades
N. Hurley-Walker, N. Rea, S. J. McSweeney +22
Recently several long-period radio transients have been discovered, with strongly polarised coherent radio pulses appearing on timescales between tens to thousands of seconds [1,2]…
A 5.3-minute-period pulsing white dwarf in a binary detected from radio to X-rays
Ingrid Pelisoli, T. R. Marsh, David A. H. Buckley +19
White dwarf stars are the most common stellar fossils. When in binaries, they make up the dominant form of compact object binary within the Galaxy and can offer insight into differ…
Australian Square Kilometre Array Pathfinder: I. System Description
A. W. Hotan, J. D. Bunton, A. P. Chippendale +63
In this paper we describe the system design and capabilities of the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope at the conclusion of its construction proje…
The Rapid ASKAP Continuum Survey I: Design and First Results
D. McConnell, C. L. Hale, E. Lenc +46
The Rapid ASKAP Continuum Survey (RACS) is the first large-area survey to be conducted with the full 36-antenna Australian Square Kilometre Array Pathfinder (ASKAP) telescope. RACS…
Field sources near the southern-sky calibrator PKS B1934-638: effect on spectral line observations with SKA-MID and its precursors
I. Heywood, E. Lenc, P. Serra +8
Accurate instrumental bandpass corrections are essential for the reliable interpretation of spectral lines from targeted and survey-mode observations with radio interferometers. Ba…
An ASKAP survey for HI absorption towards dust-obscured quasars
M. Glowacki, J. R. Allison, V. A. Moss +11
Obscuration of quasars by accreted gas and dust, or dusty intervening galaxies, can cause active galactic nuclei (AGN) to be missed in optically-selected surveys. Radio observation…
ASKAP Commissioning Observations of the GAMA 23 Field
Denis A. Leahy, A. M. Hopkins, R. P. Norris +25
We have observed the G23 field of the Galaxy And Mass Assembly (GAMA) survey using the Australian Square Kilometre Array Pathfinder (ASKAP) in its commissioning phase, to validate…
A pilot survey for transients and variables with the Australian Square Kilometre Array Pathfinder
S. Bhandari, K. W. Bannister, T. Murphy +20
We present a pilot search for variable and transient sources at 1.4 GHz with the Australian Square Kilometre Array Pathfinder (ASKAP). The search was performed in a 30 deg ar…
High-resolution Observations of Low-luminosity Gigahertz-Peaked Spectrum and Compact Steep Spectrum Sources
Jordan D. Collier, Steven J. Tingay, Joseph R. Callingham +27
We present Very Long Baseline Interferometry observations of a faint and low-luminosity ($L_{\rm 1.4 GHz} < 10^{27}~\mbox{W Hz}^{-1}$) Gigahertz-Peaked Spectrum (GPS) and Compact S…
Connecting X-ray absorption and 21cm neutral hydrogen absorption in obscured radio AGN
V. A. Moss, J. R. Allison, E. M. Sadler +22
Many radio galaxies show the presence of dense and dusty gas near the active nucleus. This can be traced by both 21cm HI absorption and soft X-ray absorption, offering new insight…
The detection of an extremely bright fast radio burst in a phased array feed survey
Keith Bannister, Ryan Shannon, Jean-Pierre Macquart +53
We report the detection of an ultra-bright fast radio burst (FRB) from a modest, 3.4-day pilot survey with the Australian Square Kilometre Array Pathfinder. The survey was conducte…
Illuminating the past 8 billion years of cold gas towards two gravitationally lensed quasars
J. R. Allison, V. A. Moss, J. -P. Macquart +15
Using the Boolardy Engineering Test Array of the Australian Square Kilometre Array Pathfinder (ASKAP BETA), we have carried out the first survey for HI and OH absorptio…
The radio spectral energy distribution of infrared-faint radio sources
A. Herzog, R. P. Norris, E. Middelberg +57
Infrared-faint radio sources (IFRS) are a class of radio-loud (RL) active galactic nuclei (AGN) at high redshifts (z > 1.7) that are characterised by their relative infrared faintn…
High-velocity OH megamasers in IRAS 20100-4156: Evidence for a Supermassive Black Hole
L. Harvey-Smith, J. R. Allison, J. A. Green +14
We report the discovery of new, high-velocity narrow-line components of the OH megamaser in IRAS 20100-4156. Results from the Australian Square Kilometre Array Pathfinder (ASKAP)'s…
