Homogeneous Velocity-Distance Data for Peculiar Velocity Analysis. I. Calibration of Cluster Samples
Jeffrey A. Willick, Stephane Courteau, Sandra M. Faber +2
We have combined five Tully-Fisher (TF) redshift-distance samples for peculiar velocity analysis: the cluster data of Han, Mould and coworkers (1991-93, HM) and Willick (1991, W91C…
Omega from the skewness of the cosmic velocity divergence
F. Bernardeau, R. Juszkiewicz, A. Dekel +1
We propose a method for measuring the cosmological density parameter from the statistics of the divergence field, , the divergence of peculiar velocity, expr…

Large-Scale Mass Distribution Behind the Galactic Plane
Tsafrir Kolatt, Avishai Dekel, Ofer Lahav
We map the smoothed mass-density distribution in the Galactic zone of avoidance (zoa), within $6000\kms$ of the Local Group, using potent reconstruction from peculiar velocities of…
