Spectroscopic-Like Temperature of Clusters of Galaxies and Cosmological Implications
P. Mazzotta, E. Rasia, S. Borgani +3
The thermal properties of hydrodynamical simulations of galaxy clusters are usually compared to observations by relying on the emission-weighted temperature T_ew, instead of on the…
Tracing the Warm Hot Intergalactic Medium in the local Universe
M. Viel, E. Branchini, R. Cen +4
We present a simple method for tracing the spatial distribution and predicting the physical properties of the Warm-Hot Intergalactic Medium (WHIM), from the map of galaxy light in…
Heated Intracluster Gas and Radio Connections: the Singular case of MKW3s
Pasquale Mazzotta, Gianfranco Brunetti, Simona Giacintucci +2
Similarly to other cluster of galaxies previously classified as cooling flow systems, the Chandra observation of MKW3s reveals that this object has a complex X-ray structure hostin…
Predictions for high-frequency radio surveys of extragalactic sources
Gianfranco De Zotti, Roberto Ricci, Dino Mesa +4
We present detailed predictions of the contributions of the various source populations to the counts at frequencies of tens of GHz. New evolutionary models are worked out for flat-…
Mismatch between X-ray and emission-weighted temperatures in galaxy clusters: cosmological implications
E. Rasia, P. Mazzotta, S. Borgani +5
The thermal properties of hydrodynamical simulations of galaxy clusters are usually compared to observations by relying on the emission-weighted temperature T_ew, instead of on the…
Comparing the temperatures of galaxy clusters from hydro-N-body simulations to Chandra and XMM-Newton observations
P. Mazzotta, E. Rasia, L. Moscardini +1
Theoretical studies of the physical processes in clusters of galaxies are mainly based on the results of numerical simulations, which in turn are often directly compared to X-ray o…
