The globular cluster luminosity function and specific frequency in dwarf elliptical galaxies.

MILLER B.W. and LOTZ J.M.

Abstract (from CDS):

The globular cluster luminosity function, specific globular cluster frequency, SN, specific globular cluster mass, TMP, and globular cluster mass fraction in dwarf elliptical galaxies are explored using the full 69 galaxy sample of the HST WFPC2 Dwarf Elliptical Galaxy Snapshot Survey. The GCLFs of the dEs are well represented with a t5 function with a peak at M0V,Z(dE,HST)=-7.3±0.1. This is ∼0.3 mag fainter than the GCLF peaks in giant spiral and elliptical galaxies, but the results are consistent within the uncertainties. The bright-end slope of the luminosity distribution has a power-law form with slope α=-1.9±0.1. The trend of increasing SN or TMPwith decreasing host galaxy luminosity is confirmed. The mean value for TMP in dE,N galaxies is about a factor of 2 higher than the mean value for nonnucleated galaxies and the distributions of TMP in dE,N and dE,noN galaxies are statistically different. These data are combined with results from the literature for a wide range of galaxy types and environments. At low host galaxy masses the distribution of TMP for dE,noN and dI galaxies are similar. This supports the idea that one pathway for forming dE,noN galaxies is by the stripping of dIs. The formation of nuclei and the larger values of TMP in dE,N galaxies may be due to higher star formation rates and star cluster formation efficiencies due to interactions in galaxy cluster environments.
