The SZ effect from cluster cavities
S. Colafrancesco
In this Letter we derive the SZ effect (SZE) observable in the direction of the giant X-ray cavities found in the atmospheres of galaxy clusters. We explore specifically the case o…
SZ effect from Dark Matter annihilation
S. Colafrancesco
We derive in this Letter the SZ effect induced by the secondary electrons produced in the annihilation of Weakly Interacting Massive Particles (assumed here to be neutralinos) in g…
Cosmic Rays and Non-Thermal Emission in Galaxy Clusters
S. Colafrancesco
We discuss the origin of thermal and non-thermal phenomena in galaxy clusters. Specifically, we present some expectations for the non-thermal emission (from radio to gamma ray wave…
Evolution with redshift of the ICM abundances
Agostino Martinelli, Francesca Matteucci, Sergio Colafrancesco
We predict the behaviour of the abundances of -elements and iron in the intracluster medium as a function of redshift in poor and rich clusters. In order to do that we calculate…
Velocity correlation tensor and substructure's statistics around density peaks
V. Antonuccio-delogu, S. Colafrancesco
We derive the conditional probability distribution of the peculiar velocity around a peak of given overdensity in a Gaussian density field. This distribution characterizes the shea…
