| Abstract | We study the total density distribution in the central regions (≾.1 effective radius, Re) of early-type galaxies (ETGs), using data from the SPIDER survey (La Barbera et al., MNRAS 408:1313, 2010). We model each galaxy with two components (dark matter halo + stars), exploring different assumptions for the dark matter (DM) halo profile, and leaving stellar mass-to-light (M*=L) ratios as free fitting parameters to the data. For a Navarro et al. (ApJ 462:563, 1996) profile, the slope of the total mass profile is non-universal. For the most massive and largest ETGs, the profile is isothermal in the central regions (~Re=2), while for the lowmass and smallest systems, the profile is steeper than isothermal, with slopes similar to those for a constant-M=L profile. For a concentration-mass relation steeper than that expected from simulations, the correlation of density slope with mass tends to flatten. Our results clearly point to a non-homology in the total mass distribution of ETGs, which simulations of galaxy formation suggest may be related to a varying role of dissipation with galaxy mass. | |||
