Cluster versus POTENT Density and Velocity Fields: Cluster Biasing and Omega
E. Branchini, I. Zehavi, M. Plionis +1
The density and velocity fields as extracted from the Abell/ACO clusters are compared to the corresponding fields recovered by the POTENT method from the Mark~III peculiar velociti…
Cosmological Parameters and Power Spectrum from Peculiar Velocities
Idit Zehavi, Avishai Dekel
The power spectrum of mass density fluctuations is evaluated from the Mark III and the SFI catalogs of peculiar velocities by a maximum likelihood analysis, using parametric models…
Correlation Analysis of SFI Peculiar Velocities
S. Borgani, L. N. da Costa, I. Zehavi +5
We present results of a statistical analysis of the SFI catalog of peculiar velocities, a recently completed survey of spiral field galaxies with I-band Tully-Fisher distances (Hay…
Large-Scale Power Spectrum and Cosmological Parameters from SFI Peculiar Velocities
Wolfram Freudling, Idit Zehavi, Luiz N. da Costa +7
We estimate the power spectrum of mass density fluctuations from peculiar velocities of galaxies by applying an improved maximum-likelihood technique to the new all-sky SFI catalog…
Evidence for a Positive Cosmological Constant from Flows of Galaxies and Distant Supernovae
Idit Zehavi, Avishai Dekel
Recent observations of high-redshift supernovae seem to suggest that the global geometry of the Universe may be affected by a `cosmological constant', which acts to accelerate the…
