Abstract:
We describe observations of the nearby (cz=11487km/s) cluster of
galaxies Abell 576 beyond the virial radius and into the infall region
where galaxies are on their first or second pass through the cluster.
Using 1057 redshifts, we use the infall pattern in redshift space to
determine the mass profile of A576 to a radius of ∼4h-1Mpc.
