The Archetypal Ultra-Diffuse Galaxy, Dragonfly 44, is not a Dark Milky Way
Akos Bogdan
Due to the peculiar properties of ultra-diffuse galaxies (UDGs), understanding their origin presents a major challenge. Previous X-ray studies demonstrated that the bulk of UDGs la…
Ultra-diffuse galaxies in the Coma cluster: Probing their origin and AGN occupation fraction
Orsolya E. Kovacs, Akos Bogdan, Rebecca E. A. Canning
Ultra-diffuse galaxies (UDGs) exhibit low surface brightness, but their optical extent is comparable to Milky Way-type galaxies. Due to their peculiar properties, it remains ambigu…
EAGLE and Illustris-TNG predictions for resolved eROSITA X-ray observations of the circumgalactic medium around normal galaxies
Benjamin D. Oppenheimer, Akos Bogdan, Robert A. Crain +8
We simulate stacked observations of nearby hot X-ray coronae associated with galaxies in the EAGLE and Illustris-TNG hydrodynamic simulations. A forward modeling pipeline is develo…
