Cosmological Zoom-In Simulation of Odd Radio Circles as Merger-Driven Shocks in Galaxy Groups
Anna Ivleva, Ludwig M. Böss, Klaus Dolag +2
Odd Radio Circles (ORCs) are a new class of distinct radio objects that has recently been discovered. The origin of these features is yet unclear because their peculiar properties…
The life of central radio galaxies in clusters: AGN-ICM studies of eRASS1 clusters in the ASKAP fields
Angie Veronica, Thomas H. Reiprich, Florian Pacaud +35
The mechanical feedback from the central AGNs can be crucial for balancing the radiative cooling of the intracluster medium at the cluster centre. We aim to understand the relation…
Stingrays in the radio sky: Two unusual diffuse radio relic sources in the direction of the Magellanic Stream
Zachary J Smeaton, Miroslav D Filipovic, Barbel S Koribalski +17
We present the discovery of two extended, low surface brightness radio continuum sources, each consisting of a near-circular body and an extended tail of emission, nicknamed Stingr…
MeerKAT radio continuum imaging of nearby star-forming spirals in the NGC 6221, NGC 3256/3263, and NGC 2434 galaxy groups
J. Saponara, B. S. Koribalski, J. English +1
Context. We present high-resolution MeerKAT 1.3 GHz radio continuum images of star-forming spirals in the nearby galaxy groups around NGC 6221, NGC 3256/3263 and NGC 2434. This sam…
Evolutionary Map of the Universe: Detection and Analysis of the Shell Surrounding the Runaway Wolf-Rayet Star WR16
A. C. Bradley, M. D. FilipoviÄ, Z. J. Smeaton +18
We present the first radio--continuum detection of the circumstellar shell around the well-known WN8 type Wolf-Rayet star WR16 at 943.5\,MHz using the \ac{ASKAP} \ac{EMU} survey. A…
EMUSE: Evolutionary Map of the Universe Search Engine
Nikhel Gupta, Zeeshan Hayder, Minh Huynh +6
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…
