Tracing stellar populations of galaxies with the SBF method
Abstract
Surface Brightness Fluctuations (SBF) are an useful distance indicator of gas-free galaxies as far as 100-150 Mpc with an accuracy of 5-10%. Recent applications have proved that the SBF technique is also a powerful tool to analyze the stellar content of elliptical-like galaxies by means of data/models comparison. Here we present a comprehensive study of the method on the base of a careful analysis of SBF models and a set of accurate multibands SBF measures obtained with HST.
