We present spherical, nonrotating, isotropic models of early-type galaxies with stellar and dark-matter components both described by deprojected Sérsic density profiles and prove that they represent physically admissible stable systems. Using empirical correlations and recent results of N-body simulations, all the free parameters of the models are expressed as functions of one single quantity: the total (B-band) luminosity of the stellar component. We analyze how to perform discrete N-body… 

Testing cosmological models with the brightness profile of distant galaxies

This work uses observed galaxy surface brightness profiles at high redshifts to determine the cosmological model best suited to interpret these observations. Theoretical predictions of galactic

SPIDER. IV. OPTICAL AND NEAR-INFRARED COLOR GRADIENTS IN EARLY-TYPE GALAXIES: NEW INSIGHT INTO CORRELATIONS WITH GALAXY PROPERTIES

We present an analysis of stellar population gradients in 4546 early-type galaxies (ETGs) with photometry in grizYHJK along with optical spectroscopy. ETGs were selected as bulge-dominated systems,

The power spectrum of systematics in cosmic shear tomography and the bias on cosmological parameters

We warmly thank J. Amiaux, M. Cropper and C. Saxton for making the Euclid PSF available and H. Hoekstra, T. Kitching, R. Massey and S. Pandolfi for useful comments on an earlier version of the
