Extended Radio Galaxies in EMU: A Comparative Look at Source-Finding Techniques
Lachlan J. Barnes, Andrew M. Hopkins, Yjan Gordon +8
Extended radio sources present unique challenges for automated detection and classification in wide-field radio surveys. With current surveys such as the Evolutionary Map of the Un…
ASKAP EMU detection of an Odd Radio Circle (ORC) candidate: J094412-751016 (Anglerfish)
M. D. Filipović, Z. J. Smeaton, A. C. Bradley +33
We report diffuse extended radio-continuum emission spatially coinciding with the IR source WISEA J094409.17-751012.8, and a semi-variable star, V687 Carinae. We use 944 MHz radio…
New Signs Pointing Toward a Correlation Between Astrophysical Neutrinos and Radio Flares
Yjan A. Gordon, Peter S. Ferguson, Eric J. Hooper +1
We use data from the first two epochs of the Very Large Array Sky Survey (VLASS) and the IceCube Neutrino Observatory to search for evidence of a correlation between radio variabil…
A Census of Variable Radio Sources at GHz
Yjan A. Gordon, Peter S. Ferguson, Michael N. Martinez +1
A wide range of phenomena, from explosive transients to active galactic nuclei, exhibit variability at radio wavelengths on timescales of a few years. Characterizing the rate and s…
EMU and the DRAGNs I: A Catalogue of DRAGNs
Ray P. Norris, Miranda Yew, Evan Crawford +10
We present a catalogue of 3557 Double Radio sources associated with Active Galactic Nuclei (DRAGNs) from the First Pilot Survey of the Evolutionary Map of the Universe (EMU), obser…
Predicting the Number of Radio Sources Seen by Both VLASS and LSST
Alex Tellez, Yjan Gordon, Keith Bechtol
Radio surveys typically sample extragalactic sources in higher redshift regimes than is typical for optical surveys, resulting in many radio sources not having a detected optical c…
Finding Lensed Radio Sources with the VLA Sky Survey
Michael N. Martinez, Yjan A. Gordon, Keith Bechtol +3
Radio observations of strongly lensed objects are valuable as cosmological probes. Lensed radio sources have proven difficult to identify in large part due to the limited depth and…
RG-CAT: Detection Pipeline and Catalogue of Radio Galaxies in the EMU Pilot Survey
Nikhel Gupta, Ray P. Norris, Zeeshan Hayder +15
We present source detection and catalogue construction pipelines to build the first catalogue of radio galaxies from the 270 pilot survey of the Evolutionary Map of the…
