摘要：
We present the first distance measurements of four distant elliptical shell galaxies obtained with the Surface Brightness Fluctuation (SBF) method, using HST images from Advanced Camera for Survey (ACS). In order to derive the distance of these galaxies, we provide new theoretical SBF magnitudes in the ACS filters using single-burst stellar population models in the 1.5-14 Gyr age interval and the 0.008-0.04 metallicity range. As result, we measure optical SBF at distances larger than 100 Mpc, providing the largest optical SBF-based distances.
