Globular clusters and the Virgo cluster distance modulus

D. A. Hanes

Open full text 40 citations

Abstract

Photometry presented by Hanes for the globular clusters associated with 20 bright galaxies in the Virgo cluster is used in an evaluation of a pure Population II distance modulus for the Virgo cluster of galaxies. The assumption of a normally distributed universal globular cluster luminosity function, calibrated in the Galaxy sample of globulars and based upon an absolute magnitude of MV = 0.6 mag for RR Lyrae stars in globular clusters, leads to Virgo cluster distance modulus estimates near |${(m - M)}_\text{app}\,=\,30.4\,\text{mag}$| with an uncertainty of ± 0.5 mag. Confirmation of a model-independent nature is presented.
