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…

Hubble constant from sosie galaxies and HIPPARCOS geometrical calibration
G. Paturel, P. Lanoix, P. Teerikorpi +5
New distances, larger than previous ones, have been obtained for M 31 and M 81 based on the geometrical zero-point of the Cepheid Period-luminosity relation provided by the HIPPARC…
