Hot X-ray coronae around massive spiral galaxies: a unique probe of structure formation models
Akos Bogdan, William R. Forman, Mark Vogelsberger +8
Luminous X-ray gas coronae in the dark matter halos of massive spiral galaxies are a fundamental prediction of structure formation models, yet only a few such coronae have been det…
LMXB populations in galaxy outskirts: globular clusters and supernova kicks
Zhongli Zhang, Marat Gilfanov, Akos Bogdan
For the first time, we have systematically explored the population of discrete X-ray sources in the outskirts of early-type galaxies. Based on a broad sample of 20 galaxies observe…
The diverse hot gas content and dynamics of optically similar low-mass elliptical galaxies
Akos Bogdan, Laurence P. David, Christine Jones +2
The presence of hot X-ray emitting gas is ubiquitous in massive early-type galaxies. However, much less is known about the content and physical status of the hot X-ray gas in low-m…
Chandra observations of NGC4342, an optically faint, X-ray gas-rich early-type galaxy
Akos Bogdan, William R. Forman, Ralph P. Kraft +10
Chandra X-ray observations of NGC4342, a low stellar mass (M_K=-22.79 mag) early-type galaxy, show luminous, diffuse X-ray emission originating from hot gas with temperature of kT~…
Exploring the unusually high black hole-to-bulge mass ratios in NGC4342 and NGC4291: the asynchronous growth of bulges and black holes
Akos Bogdan, William R. Forman, Irina Zhuravleva +10
We study two nearby, early-type galaxies, NGC4342 and NGC4291, that host unusually massive black holes relative to their low stellar mass. The observed black hole-to-bulge mass rat…
