| dc.description.abstract | We present radial photometric and spectroscopic study of a sample of the brightest cluster member of 14 cD galaxies (A193, A426, A496 ,A754, A1413, NGC 4874, NGC 4839, A1795, A2162, A2199, A2399, A2589, A2634 and A2670). We obtained the line-strength radial gradients up to 3 re in some cases and compare the models between Vazdekis et al. (2010) and Thomas, Maraston, and Bender (2003) to nd the radial age and metallicity with index-index diagrams. The results from non-emission line aected galaxies show lower metallicity at large radius with generally younger ages (A2162) and nd cases of a radial tendency towards a second nucleus (A2199). Also we included the full-spectral tting method with pPXF obtaining kinematic data like radial velocity, and velocity dispersion with radius uncovering dynamical and geometrical properties of galaxies. | |
