Odd radio circle J1555+2726: Observational evidence for shock re-acceleration of fossil plasma
L. Bruno, B. Koribalski, R. P. Norris +7
Context. Odd radio circles (ORCs) are peculiar extragalactic sources recently discovered. They are characterised by one or more bright rings extending on scales of hundreds of kilo…
ASKAP EMU detection of an Odd Radio Circle (ORC) candidate: J094412-751016 (Anglerfish)

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…
EMUSE: Evolutionary Map of the Universe Search Engine

We present EMUSE (Evolutionary Map of the Universe Search Engine), a tool designed for searching specific radio sources within the extensive datasets of the EMU (Evolutionary Map o…
Discovery of Odd Radio Circles and Other Peculiars in the First Year of the EMU Survey using Object Detection
Nikhel Gupta, Ray P. Norris, Zeeshan Hayder +9
We present a systematic search for Odd Radio Circles (ORCs) and other unusual radio morphologies using data from the first year of the EMU (Evolutionary Map of the Universe) survey…
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…
MeerKAT discovery of a MIGHTEE Odd Radio Circle
Ray P. Norris, Bärbel S. Koribalski, Catherine L. Hale +3
We present the discovery of a new Odd Radio Circle (ORC J0219--0505) in 1.2~GHz radio continuum data from the MIGHTEE survey taken with the MeerKAT telescope. The radio-bright host…
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…
Evolutionary Map of the Universe (EMU): Observations of Filamentary Structures in the Abell S1136 Galaxy Cluster
Peter. J. Macgregor, Ray P. Norris, Andrew O'Brien +17
We present radio observations of the galaxy cluster Abell S1136 at 888 MHz, using the Australian Square Kilometre Array Pathfinder radio telescope, as part of the Evolutionary Map…
ASKAP reveals the radio tail structure of the Corkscrew Galaxy shaped by its passage through the Abell 3627 cluster
Bärbel S. Koribalski, Stefan W. Duchesne, Emil Lenc +12
Among the bent tail radio galaxies common in galaxy clusters are some with long, collimated tails (so-called head-tail galaxies) shaped by their interactions with the intracluster…
The Physalis system: Discovery of ORC-like radio shells around a massive pair of interacting early-type galaxies with offset X-ray emission
Bärbel S. Koribalski, Ildar Khabibullin, Klaus Dolag +7
We present the discovery of large radio shells around a massive pair of interacting galaxies and extended diffuse X-ray emission within the shells. The radio data were obtained wit…
Are Odd Radio Circles phoenixes of powerful radio galaxies?
