Enrichment of the hot intracluster medium: numerical simulations

V. Biffi, F. Mernier, P. Medvedev

The distribution of chemical elements in the hot intracluster medium (ICM) retains valuable information about the enrichment and star formation histories of galaxy clusters, and on…

Enrichment of the hot intracluster medium: observations

F. Mernier, V. Biffi, H. Yamaguchi +7

Four decades ago, the firm detection of an Fe-K emission feature in the X-ray spectrum of the Perseus cluster revealed the presence of iron in its hot intracluster medium (ICM). Wi…

Optical Identification of X-ray Sources from the 14-Year INTEGRAL All-Sky Survey

D. I. Karasev, A. A. Lutovinov, A. Yu. Tkachenko +6

We present the results of our optical identifications of several hard X-ray sources from the INTEGRAL all-sky survey obtained over 14 years of observations. Having improved the pos…

An upper limit on nickel overabundance in the supercritical accretion disk wind of SS 433 from X-ray spectroscopy

P. Medvedev, I. Khabibullin, S. Sazonov +2

We take advantage of a long (with a total exposure time of 120 ks) X-ray observation of the unique Galactic microquasar SS 433, carried out with the XMM-Newton space observatory, t…

Diffusion of Elements in the Interstellar Medium in Early-Type Galaxies

P. Medvedev, S. Sazonov, M. Gilfanov

We consider the role of diffusion in the redistribution of elements in the hot interstellar medium (ISM) of early-type galaxies. It is well known that gravitational sedimentation c…
