Stellar dynamical evidence for dark halos in elliptical galaxies - The case of NGC 4472, IC 4296, and NGC 7144

Extended and accurate major axis kinematical profiles and line strength gradients of the elliptical galaxies NGC 4472, IC 4296, and NGC 7144 have been measured using the ESO NTT in the EMMI long-slit spectroscopic mode. For NGC 7144 the stellar rotation curve and velocity dispersion profile extend to 75″ from the center (where the surface brightness is 24.4 B-mag arcsec −2 , 2.8 mag below the sky), with typical error bars of 10 km s −1 . The flat or slowly increasing velocity dispersion profiles of these galaxies indicate that massive dark halos might dominate their dynamics
