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…
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…
Theoretical aspects of the inverse Tully-Fisher relation as a distance indicator: incompleteness in log(V_Max), the relevant slope, and the calibrator sample bias
P. Teerikorpi, T. Ekholm, M. O. Hanski +1
We study the influence of the assumption behind the use of the inverse Tully-Fisher relation: that there should be no observational cutoffs in the TF parameter log(V_M). It is note…
