The Virgo cluster distance from 21 cm-line widths
M. Federspiel, G. A. Tammann, A. Sandage
The distance of the Virgo cluster is derived in the B band from the 21 cm-line width-absolute magnitude relation. The latter is calibrated using 18 spirals with Cepheid distances m…

Focussing in on H_0
G. A. Tammann, M. Federspiel
Six independent methods yield a Virgo cluster modulus of (m-M)=31.66+/- 0.08. This inserted into the Hubble diagram of clusters, whose relative distances to the Virgo cluster are k…

H_0 from HST
G. A. Tammann, L. Labhardt, M. Federspiel +4
HST has so far provided Cepheid distances to nine galaxies. Although not sufficient yet to determine the distance of the extended Virgo cluster, they are decisive for the distance…
