Merge and Strip II: Imprint of galaxy formation physics and viscosity on baryon-dominated dwarf galaxies
Anna Ivleva, Klaus Dolag, Rhea-Silvia Remus +2
Motivated by the discovery of peculiar dwarf galaxies inside galaxy clusters such as blue candidates (BCs), dark galaxies and ultra-diffuse galaxies (UDGs), we present hydrodynamic…
Single- and double-headed odd radio circles in the LOFAR surveys
F. De Gasperin, M. Brüggen, T. Pasini +7
Deep radio surveys are now producing catalogs with millions of radio sources. Radio sources can have complex morphologies that depend on both the production mechanisms and the loca…
Encyclopedia Magneticum: Scaling Relations from Cosmic Dawn to Present Day
Klaus Dolag, Rhea-Silvia Remus, Lucas M. Valenzuela +10
Galaxy and halo scaling relations, connecting a broad range of parameters, are well established from observations. The origin of many of these relations and their scatter is still…
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…
ASKAP discovery of a 30 kpc bipolar outflow from the edge-on disk of the nearby spiral galaxy ESO 130-G012
Baerbel S. Koribalski, Roland M. Crocker, Ildar Khabibullin +6
We present the discovery of a large-scale, limb-brightened outflow, extending at least 30 kpc above and below the star-forming disk of the edge-on galaxy ESO 130-G012 (D = 16.9 Mpc…
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…
