Moreover the representative point (cumulative M / L B within the last measured point) of NGC 5266 in the diagram log ( M / L B ) - log ( R e ) falls well within the region characteristic of spiral galaxies (Figure 2, Bertola et al. 1993), as do ellipticals previously studied in...
The radiative cooling time of hot gas in the cool cores of many galaxy clusters and massive elliptical galaxies drops in the centre to below 108 yr. The mass cooling rates inferred from simple modelling of X-ray observations of these objects are very low, indicating that either active ...
which consist of more spherical groups of stars, split off into two prongs of spiral galaxies (with and without bars). The Atlas3D results suggest that this tuning fork should be replaced with a ‘comb-like’ diagram where elliptical galaxies are...
We also report on the main relations between these quantities like the fundamental plane and colour-luminosity diagram. We present observational evidences for the presence of dark matter in the elliptical galaxies and examine the theories of galaxy formation within the framework of a cold dark matter...

Cluster and field elliptical galaxies at z similar to 1.3 The marginal role of the environment and the relevance of the galaxy central Aims. The aim of this work is twofold: first, to assess whether the population of elliptical galaxies in cluster at z similar to 1 : 3 differs from the ...

THE DEEPEST HUBBLE SPACE TELESCOPE COLOR-MAGNITUDE DIAGRAM OF M32. EVIDENCE FOR INTERMEDIATE-AGE POPULATIONS* We present the deepest optical color-magnitude diagram (CMD) to date of the local elliptical galaxy M32. We have obtained F435W and F555W photometries base... A Monachesi,SC Trager,TR...
and all galaxies are shown in the same diagram. Clearly, h3 and V/σ have opposite signs. At low |V/σ|, which corre- sponds to giant ellipticals and to the central parts of other ellipticals, |h3| increases rapidly with |V/σ|. At high |V/σ|, ...
