Elliptical Galaxies in Cluster Cores: Luminosity Functions and Selection Procedures
Emilio Molinari
Abstract
We present here the results about the determination of the Luminosity Function (LF) for elliptical galaxies in the core of fairly rich clusters as a function of redshift and try to compare with the known LF of close, better studied clusters of galaxies. We then outline the first use of a new method of selecting member elliptical galaxies using an unsupervised Artificial Neural Network (ANN) working on a purely photometric set of data.
