ASKAP EMU detection of an Odd Radio Circle (ORC) candidate: J094412-751016 (Anglerfish)
M. D. FilipoviÄ, 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…
EMU Radio Observations of Barred Spiral Galaxy NGC 5938 (Araish)
H. Zakir, M. D. FilipoviÄ, L. Barnes +14
We present multi-wavelength observations of the nearby spiral galaxy NGC 5938 (Araish) to investigate the origin of its radio emission, specifically the contribution from active ga…
Cross-correlating the EMU Pilot Survey 1 with CMB lensing: Constraints on cosmology and galaxy bias with harmonic-space power spectra
K. Tanidis, J. Asorey, C. S. Saraf +8
We measured the harmonic-space power spectrum of galaxy clustering auto-correlation from the Evolutionary Map of the Universe Pilot Survey 1 data (EMU PS1) and its cross-correlatio…
Deep polarimetry study reveals double ring ORC-like structures
Sam Taziaux, Dominik J. Bomans, Christopher J. Riseley +10
New observations with the current generation of advanced radio interferometers, such as ASKAP and MeerKAT, have led to the discovery of new classes of extended radio sources of unk…
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…
Two intersecting radio shells: relics of galaxy merger shocks ?
Bärbel S. Koribalski, Klaus Dolag, Ildar Khabibullin +3
We present the discovery of two intersecting radio shells, likely radio relics, surrounding a compact galaxy group dominated by a massive elliptical galaxy. The shells present as p…
