Abstract

We present a spectral decomposition technique and its applications to a\nsample of galaxies hosting large-scale counter-rotating stellar disks. Our\nspectral decomposition technique allows to separate and measure the kinematics\nand the properties of the stellar populations of both the two counter-rotating\ndisks in the observed galaxies at the same time. Our results provide new\ninsights on the epoch and mechanism of formation of these galaxies.\n
