Energy, entropy and mass scaling relations for elliptical galaxies. Towards a physical understanding of their photometric properties
I. Marquez, G. B. Lima Neto, H. Capelato +3
In the present paper, we show that elliptical galaxies (Es) obey a scaling relation between potential energy and mass. Since they are relaxed systems in a post violent-relaxation s…

Integral field spectroscopy of the radio galaxy 3C 171
I. Marquez, E. Pecontal, F. Durret +1
We have performed integral field spectroscopy of the radio galaxy 3C 171 (redshift z=0.238) with the TIGER instrument at the Canada France Hawaii telescope in the Hbeta-[OIII]4959-…

Optical and X-ray analysis of the cluster of galaxies Abell 496
F. Durret, C. Adami, D. Gerbal +1
We present a detailed analysis of the cluster of galaxies \a4. The optical data include a redshift catalogue of 466 galaxies, out of which 274 belong to the main cluster and a CCD…
