abstract:

Cosmic velocity field provides a tracer of dark matter distribution on large scales. The bulk flow of these velocities provides a test of standard cosmological model. Using redshift 2MRS catalog and also the SNe Ia data, we find that the flow given by observations is at 1-2 sigma
consistency with Lambda-CDM model.
