Cobalt-56 gamma-ray emission lines from the type Ia supernova 2014J
E. Churazov, R. Sunyaev, J. Isern +8
A type Ia supernova is thought to be a thermonuclear explosion of either a single carbon-oxygen white dwarf or of a pair of merging white dwarfs. The explosion fuses a large amount…
Scattering of emission lines in galaxy cluster cores: measuring electron temperature
S. Khedekar, E. Churazov, S. Sazonov +2
The central galaxies of some clusters can be strong emitters in the Ly and H lines. This emission may arise either from the cool/warm gas located in the cool core of the clus…
Resonant scattering in the Perseus Cluster: spectral model for constraining gas motions with Astro-H
I. Zhuravleva, E. Churazov, R. Sunyaev +6
X-ray spectra from cores of galaxy clusters can be strongly distorted by resonant scattering of line photons, affecting metal abundance and gas velocity measurements. We introduce…
Contribution of the accretion disk, hot corona, and obscuring torus to the luminosity of Seyfert galaxies: INTEGRAL and Spitzer observations
S. Sazonov, S. P. Willner, A. D. Goulding +12
We estimate the relative contributions of the supermassive black hole (SMBH) accretion disk, corona, and obscuring torus to the bolometric luminosity of Seyfert galaxies, using Spi…
Resonant scattering in galaxy clusters for anisotropic gas motions on various spatial scales
I. Zhuravleva, E. Churazov, S. Sazonov +2
The determination of characteristic amplitudes and anisotropy of hot gas motions in galaxy clusters from observations of the brightest resonance lines is discussed. Gas motions aff…
Luminosity function of faint Galactic sources in the Chandra bulge field
M. Revnivtsev, S. Sazonov, W. Forman +2
We study the statistical properties of faint X-ray sources detected in the Chandra Bulge Field. The unprecedented sensitivity of the Chandra observations allows us to probe the pop…
