Context. Measurements of the Sunyaev-Zel'dovich (hereafter SZ) effect distortion of the cosmic microwave background provide us with an independent method to derive the gas temperature of galaxy clusters. In merging galaxy clusters the gas distribution is inhomogeneous and, therefore, the method of temperature measuring based on the SZ effect should be more relevant than that based on an X-ray emission analysis. Aims. We study a method for measuring the gas temperature in merging clusters by…

Unveiling the 3D temperature structure of galaxy clusters by means of the thermal SZ effect
The Sunyaev-Zel'dovich (hereafter SZ) effect is a promising tool to derive the gas temperature of galaxy clusters. The approximation of a spherically symmetric gas distribution is usually used to
A high-frequency study of the Sunyaev–Zel’dovich effect morphology in galaxy clusters
High-frequency, high-resolution imaging of the Sunyaev–Zel’dovich (SZ) effect is an important technique to study the complex structures of the atmospheres of merging galaxy clusters. Such
Can electron distribution functions be derived through the Sunyaev-Zel’dovich effect?
Aims. Measurements of the Sunyaev-Zel'dovich (hereafter SZ) effect distortion of the cosmic microwave background provide methods to derive the gas pressure and temperature of galaxy clusters. Here we
The first measurement of temperature standard deviation along the line-of-sight in galaxy clusters
Clusters of galaxies are mainly formed by merging of smaller structures, according to the standard cosmological scenario. If the mass of a substructure is greater than or similar to 10 per cent of
Multiwavelength mock observations of the WHIM in a simulated galaxy cluster
About half of the expected total baryon budget in the local Universe is `missing'. Hydrodynamical simulations suggest that most of the missing baryons are located in a mildly overdense, warm-hot
Empirical Test for Relativistic Kinetic Theories Based on the Sunyaev–Zel’dovich Effect
We propose a new method to determine the electron velocity (EV) distribution function in the intracluster gas (ICG) in clusters of galaxies based on the frequency dependence of the Sunyaev-Zel'dovich
Polarization of the Sunyaev-Zel'dovich effect: relativistic imprint of thermal and non-thermal plasma
Inverse Compton (IC) scattering of the anisotropic CMB fluctuations off cosmic electron plasmas generates a polarization of the associated Sunyaev-Zel'dovich (SZ) effect. The polarized SZ effect has
How AGN feedback and metal cooling shape cluster entropy profiles
Observed clusters of galaxies essentially come in two flavors: non cool core clusters characterized by an isothermal temperature profile and a central entropy floor, and cool-core clusters where
The Sunyaev-Zel'dovich (SZ) effect spectrum crosses through a null where ΔT CMB = 0 near ν0 = 217 GHz. In a cluster of galaxies, ν0 can be shifted from the canonical thermal SZ effect value by


First Measurement of Cluster Temperature Using the Thermal Sunyaev-Zel'dovich Effect
We discuss a new method of finding cluster temperatures that is independent of distance and is therefore very useful for distant clusters. The hot gas of electrons in clusters of galaxies scatters
The Sunyaev Zel'dovich temperature of the intracluster medium
The relativistic Sunyaev–Zel’dovich (SZ) effect offers a method, independent of X-ray, for measuring the temperature of the intracluster medium (ICM) in the hottest systems. Here, using
An analysis of electron distributions in galaxy clusters by means of the flux ratio of iron lines FeXXV and XXVI
Aims. The interpretation of hard X-ray emission from galaxy clusters is still ambiguous and different proposed models can be probed using various observational methods. Here we explore a new method
The Sunyaev-Zel’dovich Effect
Abstract The Sunyaev–Zel’dovich effect causes a change in the apparent brightness of the cosmic microwave background radiation towards a cluster of galaxies or any other reservoir of hot plasma.
Relativistic Corrections to the Sunyaev-Zeldovich Effect
We present an extension of the Kompaneets equation which allows relativistic effects to be included to any desired order. Using this, we are able to obtain simple analytic forms for the spectral

Very Large Array telescope observations of ring-shaped nonthermal radio-emitting structures found at the outskirts of the rich cluster of galaxies Abell 3376 are reported, which may trace the elusive shock waves of cosmological large-scale matter flows, which are energetic enough to power them.
