The increasing sensitivity of current experiments, which nowadays routinely measure the thermal SZ effect within galaxy clusters, provide the hope that peculiar velocities of individual clusters of galaxies will be measured rather soon using the kinematic SZ effect. Also next generation of X-ray telescopes with microcalorimeters, promise first detections of the motion of the intra cluster medium (ICM) within clusters. We used a large set of cosmological, hydrodynamical simulations, which cover… 
Peculiar motions of galaxy clusters and groups in the Hercules and Leo supercluster regions
We present the results of our study of the peculiar motions for 41 galaxy clusters and groups in the regions of the Hercules and Leo superclusters (0.027 < z < 0.045). For this purpose, based on SDSS
Matched filter optimization of kSZ measurements with a reconstructed cosmological flow field
We develop and test a new statistical method to measure the kinematic Sunyaev-Zel'dovich (kSZ) effect. A sample of independently detected clusters is combined with the cosmic flow field predicted
Polarization of Sunyaev-Zel'dovich signal due to electron pressure anisotropy in galaxy clusters
We describe polarization of the Sunyaev-Zel’dovich (SZ) effect associated with electron pressure anisotropy likely present in the intracluster medium (ICM). The ICM is an astrophysical example of a
Planck intermediate results: XXXVII. Evidence of unbound gas from the kinetic Sunyaev-Zeldovich effect
By looking at the kinetic Sunyaev-Zeldovich effect (kSZ) in Planck nominal mission data, we present a significant detection of b aryons participating in large-scale bulk flows around central galaxies
Cosmology with the pairwise kinematic SZ effect: calibration and validation using hydrodynamical simulations
We study the potential of the kinematic Sunyaev-Zel'dovich (kSZ) effect as a probe for cosmology, focusing on the pairwise method. The main challenge is disentangling the cosmologically interesting
Offsets between the X-ray and the Sunyaev-Zel'dovich-effect peaks in merging galaxy clusters and their cosmological implications
Observations reveal that the peaks of the X-ray map and the Sunyaev-Zel'dovich (SZ) effect map of some galaxy clusters are offset from each other. In this paper, we perform a set of hydrodynamical
A Study of the Merger History of the Galaxy Group HCG 62 Based on X-Ray Observations and Smoothed Particle Hydrodynamic Simulations
We choose the bright compact group HCG 62, which was found to exhibit both excess X-ray emission and high Fe abundance to the southwest of its core, as an example to study the impact of mergers on
Motion induced second order temperature and y-type anisotropies after the subtraction of linear dipole in the CMB maps
y-type spectral distortions of the cosmic microwave background allow us to detect clusters and groups of galaxies, filaments of hot gas and the non-uniformities in the warm hot intergalactic medium.
Simulating the galaxy cluster "El Gordo" and identifying the merger configuration
The observational features of the massive galaxy cluster "El Gordo" (ACT-CL J0102-4915), such as the X-ray emission, the Sunyaev-Zel'dovich (SZ) effect, and the surface mass density distribution,
Simulations of the Pairwise Kinematic Sunyaev-Zel'dovich Signal
The pairwise kinematic Sunyaev-Zel'dovich (kSZ) signal from galaxy clusters is a probe of their line-of-sight momenta, and thus a potentially valuable source of cosmological information. In addition


Effect of internal flows on Sunyaev-Zeldovich measurements of cluster peculiar velocities
Galaxy clusters are potentially powerful probes of the large-scale velocity field in the universe because their peculiar velocity can be estimated directly via the kinematic Sunyaev-Zeldovich effect
Measuring cluster peculiar velocities with the Sunyaev-Zel'dovich effect: scaling relations and systematics
The fluctuations in the cosmic microwave background (CMB) intensity due to the Sunyaev-Zel'dovich (SZ) effect are the sum of a thermal and a kinetic contribution. Separating the two components to
Large-Scale Motions in Superclusters: Their Imprint in the Cosmic Microwave Background.
It is shown that the thermal effect dominates the kinematic effect and that the largest thermal decrements are associated with the most massive clusters in superclusters, and searching for the presence of two or more nearby large CMB decrements represents a viable strategy for identifying supercluster at cosmological distances.
Substructures in hydrodynamical cluster simulations
The abundance and structure of dark matter subhaloes have been analysed extensively in recent studies of dark-matter-only simulations, but comparatively little is known about the impact of baryonic
Investigating the velocity structure and X-ray observable properties of simulated galaxy clusters with PHOX
Non-thermal motions in the intra-cluster medium (ICM) are believed to play a non-negligible role in the pressure support to the total gravitating mass of galaxy clusters. Future X-ray missions, such

Chemical enrichment of galaxy clusters from hydrodynamical simulations
We present cosmological hydrodynamical simulations of galaxy clusters aimed at studying the process of metal enrichment of the intra-cluster medium (ICM). These simulations have been performed by

Coolingflows, cluster mergers, and the motions of galaxies through cluster gas with supersonic and sonic velocities must lead to large scale motions of the intracluster medium (ICM). A
