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…
The Evolutionary Map of the Universe: A new radio atlas for the southern hemisphere sky
A. M. Hopkins, A. Kapinska, J. Marvil +70
We present the Evolutionary Map of the Universe (EMU) survey conducted with the Australian Square Kilometre Array Pathfinder (ASKAP). EMU aims to deliver the touchstone radio atlas…
ASKAP and VLASS search for a radio-continuum counterpart of ultra-high-energy neutrino event KM3-230213A
M. D. Filipović, Z. J. Smeaton, A. C. Bradley +23
We present the results of an Australian Square Kilometre Array Pathfinder (ASKAP) 944 MHz and Very Large Array Sky Survey (VLASS) 3~GHz search for a radio-continuum counterpart of…
Diprotodon on the sky. The Large Galactic Supernova Remnant (SNR) G278.94+1.35
Miroslav D. Filipović, S. Lazarević, M. Araya +41
We present a re-discovery of G278.94+1.35 as possibly one of the largest known Galactic supernova remnants (SNR) - that we name Diprotodon. While previously established as a Galact…
The MeerKAT 1.3 GHz Survey of the Small Magellanic Cloud
W. Cotton, M. D. Filipovic, F. Camilo +22
We present new radio continuum images and a source catalogue from the MeerKAT survey in the direction of the Small Magellanic Cloud (SMC). The observations, at a central frequency…
Selection of powerful radio galaxies with machine learning
R. Carvajal, I. Matute, J. Afonso +12
We developed and trained a pipeline of three machine learning (ML) models than can predict which sources are more likely to be an AGN and to be detected in specific radio surveys.…
Measuring photometric redshifts for high-redshift radio source surveys
Kieran J. Luken, Ray P. Norris, X. Rosalind Wang +3
With the advent of deep, all-sky radio surveys, the need for ancillary data to make the most of the new, high-quality radio data from surveys like the Evolutionary Map of the Unive…
MeerKAT uncovers the physics of an Odd Radio Circle
Ray P. Norris, J. D. Collier, Roland M. Crocker +14
Odd Radio Circles (ORCs) are recently-discovered faint diffuse circles of radio emission, of unknown cause, surrounding galaxies at moderate redshift ($z ~ 0.2-0.6). Here we presen…
Estimating Galaxy Redshift in Radio-Selected Datasets using Machine Learning
Kieran J. Luken, Ray P. Norris, Laurence A. F. Park +2
All-sky radio surveys are set to revolutionise the field with new discoveries. However, the vast majority of the tens of millions of radio galaxies won't have the spectroscopic red…
Mysterious Odd Radio Circle near the Large Magellanic Cloud -- An Intergalactic Supernova Remnant?
Miroslav D. Filipović, J. L. Payne, R. Z. E. Alsaberi +48
We report the discovery of J0624-6948, a low-surface brightness radio ring, lying between the Galactic Plane and the Large Magellanic Cloud (LMC). It was first detected at 888 MHz…
Missing Data Imputation for Galaxy Redshift Estimation
Kieran J. Luken, Rabina Padhy, X. Rosalind Wang
Astronomical data is full of holes. While there are many reasons for this missing data, the data can be randomly missing, caused by things like data corruptions or unfavourable obs…
The Evolutionary Map of the Universe Pilot Survey
Ray P. Norris, Joshua Marvil, J. D. Collier +45
We present the data and initial results from the first Pilot Survey of the Evolutionary Map of the Universe (EMU), observed at 944 MHz with the Australian Square Kilometre Array Pa…
Unexpected Circular Radio Objects at High Galactic Latitude
Ray P. Norris, Huib T. Intema, Anna D. Kapinska +26
We have found a class of circular radio objects in the Evolutionary Map of the Universe Pilot Survey, using the Australian Square Kilometre Array Pathfinder telescope. The objects…
Radio Observations of Supernova Remnant G1.9+0.3
Kieran J. Luken, Miroslav D. Filipović, Nigel I. Maxted +18
We present 1 to 10GHz radio continuum flux density, spectral index, polarisation and Rotation Measure (RM) images of the youngest known Galactic Supernova Remnant (SNR) G1.9+0.3, u…
Discovery of a Pulsar-powered Bow Shock Nebula in the Small Magellanic Cloud Supernova Remnant DEMS5
Rami Z. E. Alsaberi, C. Maitra, M. D. Filipovi'c +32
We report the discovery of a new Small Magellanic Cloud Pulsar Wind Nebula (PWN) at the edge of the Supernova Remnant (SNR)-DEM S5. The pulsar powered object has a cometary morphol…
A Comparison of Photometric Redshift Techniques for Large Radio Surveys
Ray P. Norris, M. Salvato, G. Longo +14
Future radio surveys will generate catalogues of tens of millions of radio sources, for which redshift estimates will be essential to achieve many of the science goals. However, sp…
Preliminary results of using k-Nearest Neighbours Regression to estimate the redshift of radio selected datasets
Kieran J. Luken, Ray P. Norris, Laurence A. F. Park
In the near future, all-sky radio surveys are set to produce catalogues of tens of millions of sources with limited multi-wavelength photometry. Spectroscopic redshifts will only b…
