Large scale motions in superclusters: their imprint in the CMB
Antonaldo Diaferio, Rashid A. Sunyaev, Adi Nusser
We identify high density regions of supercluster size in high resolution N-body simulations of a representative volume of three Cold Dark Matter Universes. By assuming that (1) the…
Topology and Geometry of the CfA2 Redshift Survey
Jens Schmalzing, Antonaldo Diaferio
We analyse the redshift space topology and geometry of the nearby Universe by computing the Minkowski functionals of the Updated Zwicky Catalogue (UZC). The UZC contains the redshi…
Ab Initio Formation of Galaxies, Groups and Large-Scale Structure
Antonaldo Diaferio
For the first time, the combination of semi-analytic modelling of galaxy formation and N-body simulations of cosmic structure formation enables us to model, at the same time, both…
Mass estimation in the outer regions of galaxy clusters
Antonaldo Diaferio
We present a technique for estimating the mass in the outskirts of galaxy clusters where the usual assumption of dynamical equilibrium is not valid. The method assumes that cluster…
The Mass Profile of the Coma Galaxy Cluster
M. J. Geller, Antonaldo Diaferio, M. J. Kurtz
We use a new redshift survey complete to m_R=15.4 within 4.25 deg from the center of the Coma cluster to measure the mass profile of the cluster to r=5.5 Mpc/h. We extend the profi…
