Interpretation of LargeScale Deviations from the Hubble Flow
Abstract
The theoretical expectation for largescale streaming velocities relative to the Hubble flow is expressed in terms of statistical correlation functions. Only for objects that trace the mass would these velocities have a simple cosmological interpretation. If some biasing effects the objects' formation, then nonlinear gravitational evolution is essential to predicting the expected largescale velocities, which also depend on the nature of the biasing.
