Intracluster Extinction of Light from Galaxies in Virgo

We have analyzed existing data on colours and Tully-Fisher distances of a sample of spiral galaxies in the Virgo cluster. The data seem to indicate a significant correlation between the colour-excesses and distances of these galaxies. This correlation may be due to extinction by intracluster (IC) dust. However, due to uncertainties in the observational data, and the limited size of the sample, such an interpretation may not yet be construed as an unequivocal evidence for dust in the Virgo cluster of galaxies.
