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 ( Mpc) stated by Sandage(1986, 1999) is studied. New observational data on galaxy motions and matt…
On the quiescence of the Hubble flow in the vicinity of the Local Group
T. Ekholm, Yu. Baryshev, P. Teerikorpi +2
Cepheid distances of local galaxies (<7 Mpc) are used to study the very nearby velocity field, as pioneered by Sandage (Sandage 1986) who also pointed out its remarkable properties…
Why is the Hubble flow so quiet?
Arthur Chernin, Pekka Teerikorpi, Yurij Baryshev
The cosmological vacuum, which is perfectly uniform, dominates by density over all the forms of cosmic matter. It makes the Universe be actually more uniform than it could be seen…
Investigations of the Local Supercluster Velocity Field III. Tracing the backside infall with distance moduli from the direct Tully-Fisher relation
T. Ekholm, P. Lanoix, P. Teerikorpi +2
We have extended the discussion of Paper II (Ekholm et al. 1999) to cover also the backside of the Local Supercluster (LSC) by using 96 galaxies within Theta<30 deg from the adopte…
Investigations of the Local Supercluster Velocity Field II. A study using Tolman-Bondi solution and galaxies with accurate distances from the Cepheid PL-relation
T. Ekholm, P. Lanoix, P. Teerikorpi +2
A sample of 32 galaxies with accurate distance moduli from the Cepheid PL-relation (Lanoix 1999) has been used to study the dynamical behaviour of the Local (Virgo) supercluster. W…
Evidence for dark matter in different scales from the KLUN galaxy sample
M. O. Hanski, P. Teerikorpi, T. Ekholm +4
The KLUN (Kinematics of the Local UNiverse) sample of 6600 spiral galaxies is used in studying dark matter in different scales: Type dependence of the zero-point of Tully-Fisher re…
