Structures and components in galaxy clusters: observations and models
A. M. Bykov, E. M. Churazov, C. Ferrari +5
Clusters of galaxies are the largest gravitationally bounded structures in the Universe dominated by dark matter. We review the observational appearance and physical models of plas…
Planck intermediate results. XL. The Sunyaev-Zeldovich signal from the Virgo cluster
Planck Collaboration, P. A. R. Ade, N. Aghanim +202
The Virgo cluster is the largest Sunyaev-Zeldovich (SZ) source in the sky, both in terms of angular size and total integrated flux. Planck's wide angular scale and frequency covera…
Does the obscured AGN fraction really depend on luminosity?
Sergey Sazonov, Eugene Churazov, Roman Krivonos
We use a sample of 151 local non-blazar AGN selected from the INTEGRAL all-sky hard X-ray survey to investigate if the observed declining trend of the fraction of obscured (i.e. sh…
A Deep XMM-Newton Study of the Hot Gaseous Halo Around NGC 1961
Michael E. Anderson, Eugene Churazov, Joel N. Bregman
We examine 11 XMM-Newton observations of the giant spiral galaxy NGC 1961, allowing us to study the hot gaseous halo of a spiral galaxy in unprecedented detail. We perform a spatia…
Comparison of simple mass estimators for slowly rotating elliptical galaxies
N. Lyskova, J. Thomas, E. Churazov +2
We compare the performance of mass estimators for elliptical galaxies that rely on the directly observable surface brightness and velocity dispersion profiles, without invoking com…
(No) dimming of X-ray clusters beyond z~1 at fixed mass: crude redhshifts and masses from raw X-ray and SZ data
E. Churazov, A. Vikhlinin, R. Sunyaev
Scaling relations in the LCDM Cosmology predict that for a given mass the clusters formed at larger redshift are hotter, denser and therefore more luminous in X-rays than their loc…
