Distances and Stellar Population properties using the SBF method

TL;DR

This paper demonstrates that the Surface Brightness Fluctuations (SBF) method can accurately measure distances and stellar population properties of galaxies across a wide range of scales, from nearby to distant systems.

Contribution

It shows the effectiveness of the SBF technique in determining galaxy distances and constraining stellar population characteristics.

Findings

SBF method provides accurate distances from ~10 Kpc to ~150 Mpc.

SBF reliably constrains age and metallicity of unresolved stellar systems.

The technique is effective for both resolved and unresolved systems.

Abstract

We present some results on the study of stellar population properties and distances of galaxies using the SBF technique. The applications summarized here show that the Surface Brightness Fluctuations (SBF) method is able to i) provide accurate distances of resolved and unresolved stellar systems from ~10 Kpc to ~150 Mpc, and ii) to reliably constrain the physical properties (e.g. age and metallicity) of unresolved stellar systems.
