We present the detection of 661 known pulsars observed with the Australian SKA Pathfinder (ASKAP) telescope at 888 MHz as a part of the Rapid ASKAP Continuum Survey (RACS). Detecti…
Gems of the Galaxy Zoos -- a Wide-Ranging Hubble Space Telescope Gap-Filler Program
William C. Keel, Jean Tate, O. Ivy Wong +13
We describe the Gems of the Galaxy Zoos (Zoo Gems) project, a gap-filler project using short windows in the Hubble Space Telescope's schedule. As with previous snapshot programs, t…
The Black Hole-Galaxy Connection: Interplay between Feedback, Obscuration, and Host Galaxy Substructure
Stéphanie Juneau, Andy D. Goulding, Julie Banfield +20
There is growing evidence for physical influence between supermassive black holes and their host galaxies. We present a case study of nearby galaxy NGC 7582, for which we find evid…
A search for radio afterglows from gamma-ray bursts with the Australian Square Kilometre Array Pathfinder
James K. Leung, Tara Murphy, Giancarlo Ghirlanda +12
We present a search for radio afterglows from long gamma-ray bursts using the Australian Square Kilometre Array Pathfinder (ASKAP). Our search used the Rapid ASKAP Continuum Survey…

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…
An ASKAP search for a radio counterpart to the first high-significance neutron star-black hole merger LIGO/Virgo S190814bv
Dougal Dobie, Adam Stewart, Tara Murphy +27
We present results from a search for a radio transient associated with the LIGO/Virgo source S190814bv, a likely neutron star-black hole (NSBH) merger, with the Australian Square K…
Radio Galaxy Zoo: Observational evidence for environment as the cause of radio source asymmetry
P. E. Rodman, R. J. Turner, S. S. Shabala +7
We investigate the role of environment on radio galaxy properties by constructing a sample of large (~kpc), nearby () radio sources identified as part of the Rad…
Radio Galaxy Zoo: Machine learning for radio source host galaxy cross-identification
M. J. Alger, J. K. Banfield, C. S. Ong +6
We consider the problem of determining the host galaxies of radio sources by cross-identification. This has traditionally been done manually, which will be intractable for wide-are…
Radio Galaxy Zoo: ClaRAN - A Deep Learning Classifier for Radio Morphologies
Chen Wu, O. Ivy Wong, Lawrence Rudnick +13
The upcoming next-generation large area radio continuum surveys can expect tens of millions of radio sources, rendering the traditional method for radio morphology classification t…
Optical Detection of Star Formation in a Cold Dust Cloud in the Counterjet Direction of Centaurus A
William C. Keel, Julie K. Banfield, Anne Medling +1
We identify optical emission-line features 700" (12 kpc) southwest of the nucleus of Centaurus A, roughly opposite the radio jet and well-known optical emission filaments associate…
A Multi-Frequency Study of the Milky Way-like Spiral Galaxy NGC 6744
Miranda Yew, Miroslav D. Filipović, Quentin Roper +14
We present a multi-frequency study of the intermediate spiral SAB(r)bc type galaxy NGC 6744, using available data from the Chandra X-Ray telescope, radio continuum data from the Au…
Radio Galaxy Zoo: Compact and extended radio source classification with deep learning
V. Lukic, M. Brüggen, J. K. Banfield +4
Machine learning techniques have been increasingly useful in astronomical applications over the last few years, for example in the morphological classification of galaxies. Convolu…
