Abstract (from CDS):

We have extended the discussion of Paper II (Ekholm et al., 1999A&A...351..827E) to cover also the backside of the Local Supercluster (LSC) by using 96 galaxies within Θ<30° from the adopted centre of LSC and with distance moduli from the direct B-band Tully-Fisher relation. In order to minimize the influence of the Malmquist bias we required logVmax>2.1 and σBT<0.2mag. We found out that if RVirgo<20Mpc this sample fails to follow the expected dynamical pattern from the Tolman-Bondi (TB) model. When we compared our results with the Virgo core galaxies given by Federspiel et al. (1998ApJ...495..115F) we were able to constrain the distance to Virgo: RVirgo=20-24Mpc. When analyzing the TB-behaviour of the sample as seen from the origin of the metric as well as that with distances from the extragalactic Cepheid PL-relation we found additional support to the estimate RVirgo=21Mpc given in Paper II. Using a two-component mass-model we found a Virgo mass estimate MVirgo=(1.5-2)Mvirial, where Mvirial=9.375x1014^M for RVirgo=21Mpc. This estimate agrees with the conclusion in Paper I (Teerikorpi et al., 1992A&A...260...17T). Our results indicate that the density distribution of luminous matter is shallower than that of the total gravitating matter when q0≤0.5. The preferred exponent in the density power law, α≃2.5, agrees with recent theoretical work on the universal density profile of dark matter clustering in an Einstein-deSitter universe (Tittley & Couchman, 1999, in press).
