Morphological evolution of X-ray clusters using hydrodynamical simulations
R. Valdarnini, S. Ghizzardi, S. Bonometto
A large set of TREESPH simulations is used to test the global morphology of galaxy clusters and its evolution against X-ray data. A powerful method to investigate substructures in…
Global cluster morphology and its evolution: X-ray data vs CDM, LCDM and mixed models
R. Valdarnini, S. Ghizzardi, S. A. Bonometto
The global structure of galaxy clusters and its evolution are tested within a large set of TREESPH simulations, so to allow a fair statistical comparison with available X-ray data.…
Evolution of Cluster Morphology: X-ray data vs. CDM models
R. Valdarnini, S. Ghizzardi, S. Bonometto
We compare the evolution of morphology in X-ray cluster data and in clusters obtained in a simulation of flat CDM, normalized to the observed cluster abundance. We find that the ev…
Phase--space Distribution of Volatile Dark Matter
S. Ghizzardi, S. A. Bonometto
We discuss the phase--space distribution of neutrinos if neutrinos are unstable and decay into . If this scalar is a familon or a Majoron, in the generic case…
