KLUN+ peculiar velocity survey
M O Hanski
The enhanced Kinematics of the Local Universe (KLUN+) galaxy sample is a collection of galaxies suitable for Tully-Fisher (TF) or Faber-Jackson (FJ) distance estimation. Here we ex…
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…
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…
