Unresolved and diffuse components of X-ray emission and X/K luminosity ratios in nearby early-type and late-type galaxies
Akos Bogdan, Marat Gilfanov
We explore the nature of unresolved X-ray emission in a broad sample of galaxies of all morphological types based on archival Chandra data. After removing bright compact sources, w…

Chandra and ROSAT observations of Abell 194: detection of an X-ray cavity and mapping the dynamics of the cluster
Akos Bogdan, Ralph P. Kraft, William R. Forman +6
Based on Chandra and ROSAT observations, we investigated the nearby poor cluster Abell 194, which hosts two luminous radio galaxies, NGC547 (3C 40B) and NGC541 (3C 40A). We demonst…

Progenitors of type Ia supernovae in elliptical galaxies
Marat Gilfanov, Akos Bogdan
Although there is a nearly universal agreement that type Ia supernovae are associated with the thermonuclear disruption of a CO white dwarf, the exact nature of their progenitors i…
