The Hubble Flow Why Does the Cosmological Expansion Preserve its Kinematical Identity from a Few MPC Distance to the Observation Horizon?

Igor D. Karachentsev, Arthur D. Chernin, Pekka Teerikorpi

The problem of the physical nature of the Hubble flow in the Local Volume ($D<10$ Mpc) stated by Sandage(1986, 1999) is studied. New observational data on galaxy motions and matt…
