Statistical Models for Globular Cluster Luminosity Distribution
We consider statistical models which have been proposed for luminosity distributions for the globular clusters in the Milky Way and M31. Although earlier research showed that the cluster luminosity functions in those two galaxies were well fit by Gaussian distributions, subsequent investigations suggested that their luminosities were better fit by t-, rather than Gaussian, distributions. By app...
متن کاملThe Globular Cluster Luminosity Functions of Brightest Cluster Galaxies
A new technique for studying globular cluster populations around relatively distant galaxies is developed and applied to a sample of 23 galaxies in 19 Abell clusters. The technique is based on the surface brightness fluctuations method of determining galaxy distances. The galaxies in this sample range in redshift from 5000 to 10,000 km s1, and were selected from the Lauer & Postman (1994) surve...
متن کاملThe Globular Cluster Luminosity Function as a Distance Indicator : Dynamical
The dynamical evolution of the globular cluster systems in galaxies is predicted, based on the standard dynamical theory normalized to the example of the Milky Way. The major processes varying with the galactocentric distance are the tidal shocks and dynamical friction. Our simple model explains, on a quantitative basis, the observed diierences of the inner and outer populations of globular clu...
متن کاملThe Luminosity and Mass Function of the Globular Cluster
I-band CCD images of two large regions of the Galactic globular cluster NGC 1261 have been used to construct stellar luminosity functions (LF) for 14000 stars in three annuli from 1. ′ 4 from the cluster center to the tidal radius. The LFs extend to M I ∼ 8 and tend to steepen from the inner to the outer annulus, in agreement with the predictions of the multimass King–Michie model that we have ...
