Formation of galaxy clusters corresponds to the collapse of the largest gravitationally bound
overdensities in the initial density field and is accompanied by the most energetic …

Cosmological constraints from X-ray and microwave observations of galaxy clusters are
subjected to systematic uncertainties. Non-thermal pressure support due to internal gas …

Collisions between galaxy clusters provide a unique opportunity to study matter in a
parameter space which cannot be explored in our laboratories on Earth. In the standard …

Galaxy clusters exhibit remarkable self-similar behavior which allows us to establish simple
scaling relationships between observable quantities and cluster masses, making galaxy …

Abstract Approximate Bayesian Computation (ABC) enables parameter inference for
complex physical systems in cases where the true likelihood function is unknown …

The knowledge of the dynamical state of galaxy clusters allows to alleviate systematics
when observational data from these objects are applied in cosmological studies. Evidence …

Temperature measurements of galaxy clusters are used to determine their masses, which in
turn are used to determine cosmological parameters. However, systematic differences …

Aims. We present a detailed study of the giant radio halo in the galaxy cluster Abell 697 to
constrain its origin and connection with the cluster dynamics. Methods. We performed high …

ABSTRACT The Sunyaev–Zel'dovich effect (SZE) observable-mass (Y–M) scaling relation is
a promising technique for obtaining mass estimates for large samples of galaxy clusters and …

The thermal and chemical properties of the hot diffuse intragroup medium (IGrM) provide
important constraints on the feedback processes associated with massive galaxy formation …
