Measuring the non-thermal pressure in early type galaxy atmospheres: A comparison of X-ray and optical potential profiles in M87 and NGC1399
E. Churazov, W. Forman, A. Vikhlinin +3
We compare the gravitational potential profiles of the elliptical galaxies NGC 4486 (M87) and NGC 1399 (the central galaxy in the Fornax cluster) derived from X-ray and optical dat…
Cumulative hard X-ray spectrum of local AGN: a link to the cosmic X-ray background
S. Sazonov, R. Krivonos, M. Revnivtsev +2
We determine the cumulative spectral energy distribution (SED) of local AGN in the 3-300 keV band and compare it with the spectrum of the cosmic X-ray background (CXB) in order to…
On the width of cold fronts in clusters of galaxies due to conduction
F. Xiang, E. Churazov, K. Dolag +2
We consider the impact of thermal conduction in clusters of galaxies on the (unmagnetized) interface between a cold gaseous cloud and a hotter gas flowing over the cloud (the so-ca…
4U 0115+63 from RXTE and INTEGRAL Data: Pulse Profile and Cyclotron Line Energy
S. S. Tsygankov, A. A. Lutovinov, E. M. Churazov +1
We analyze the observations of the transient X-ray pulsar 4U 0115+63 with the RXTE and INTEGRAL observatories in a wide X-ray (3-100 keV) energy band during its intense outbursts i…
INTEGRAL/IBIS all-sky survey in hard X-rays
R. Krivonos, M. Revnivtsev, A. Lutovinov +3
We present results of an all-sky hard X-ray survey based on almost four years of observations with the IBIS telescope on board the INTEGRAL observatory. The dead time-corrected exp…
