X-ray Observations of the Chemical Abundances in the Intra-Cluster Medium [PDF]
arXiv, 2014 Clusters of galaxies as the largest clearly defined objects in our Universe are ideal laboratories to study the distribution of the most abundant chemical elements heavier than hydrogen and helium and the history of their production. The cluster environment allows us to study the element abundances not only inside the galaxies, but also in the ...

Entropy of the intracluster medium at high redshift [PDF]
, 2004 Recent observations of entropy of intracluster medium (ICM) at high redshift are not consistent with a redshift independent entropy floor. In order to interpret these observations, we study models in which the entropy of ICM is enhanced at the epoch of cluster formation (z_f), which then passively evolves as a result of radiative cooling until the ...

Chemical Evolution Of Galaxies And Intracluster Medium [PDF]
, 2004 In this series of lectures I discuss the basic principles and the modelling of the chemical evolution of galaxies. In particular, I present models for the chemical evolution of the Milky Way galaxy and compare them with the available observational data.

The Magnetothermal Instability in the Intracluster Medium [PDF]
The Astrophysical Journal, 2008 The electron mean free path in the intracluster medium (ICM) of galaxy clusters is much larger than the gyroradius; thus, heat is transported anisotropically along magnetic field lines. We show that the intracluster medium is unstable to the magnetothermal instability (MTI) using MHD simulations with anisotropic thermal conduction.

Cosmological simulations of the intracluster medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We investigate the properties of the intracluster medium (ICM) that forms within N-body/hydrodynamical simulations of galaxy clusters in a \LambdaCDM cosmology. When radiative cooling and a simple model for galactic feedback are included, our clusters have X-ray luminosities and temperatures in good agreement with observed systems, demonstrating the ...

Evidence for strong intracluster magnetic fields in the early Universe [PDF]
, 2021 The origin of magnetic fields in clusters of galaxies is still a matter of debate. Observations for intracluster magnetic fields over a wide range of redshifts are crucial to constrain possible scenarios for the origin and evolution of the fields. (Differences of Faraday rotation measures (RMs) of an embedded double radio sources, i.e.

Broad Band Optical Polarimetric Study of IC 1805 [PDF]
, 2007 We present the BVR broad band polarimetric observations of 51 stars belonging to the young open cluster IC 1805. Along with the photometric data from the literature we have modeled and subtracted the foreground dust contribution from the maximum ...
