A code computing consistently the evolution of stars, gas and dust, as well as the energy they radiate, is required to derive reliably the history of galaxies by fitting synthetic SEDs to multiwavelength observations. The new code P\'egase.3 describe

Using the new evolutionary code PEGASE. 3, we undertook an evolutionary spectral synthesis of the optical-IR-submm spectral energy distribution of two distant (z = 3.8) radio galaxies, 4C 41.17 and TN J2007-1316. These two radio galaxies were selecte

We present a study of the complete ultraviolet to submillimetre spectral energy distributions (SEDs) of twelve 3CR radio galaxy hosts in the redshift range $1.0 < z < 2.5$, which were all detected in the far-infrared by the Herschel Space Observatory

Classification and parametrization of unresolved galaxies to be detected by Gaia is the goal of our contribution to DPAC/CU8. Gaia will observe more than several times 10 6 unresolved galaxies seen almost as point sources. For the classification and

We present a detailed reduction of a mid-infrared 12 µ m( LW10 filter) ISOCAM open time observation performed on the ESOSculptor Survey field (Arnouts et al. 1997, AA these methods yield consistent results. We also apply an empirical flux density ca

We hereafter aim to present mass estimates and main parameters of distant powerful radio sources, respectively for evolved stars, ionized gas, and dust. Observations and models are consistent with a scenario where large masses are accumulated whithin

The spectra of the powerful 3CR radio galaxies present a typical distribution in the far-infrared. From the observed radio to X-ray spectral energy distribution (SED) templates, we propose to subtract the typical energy distributions of, respectively

The narrow K-z relation of powerful radio galaxies in the Hubble K diagram is often attributed to the stellar populations of massive elliptical galaxies. Extended over a large range of redshifts (0 4 implies that massive clouds were already formed at

Distant radio galaxies, observed up to the highest redshifts ( z ≃6), are characterized by intense emission lines. Measuring emission line ratios bring clues on ionizing processes. When massive stars are ionizing sources, they give the information

We have analyzed the ultraviolet and optical emission line ratios of a large sample of extragalactic radio sources (QSOs and radio galaxies), with the help of models combining AGN photoionization and shocks. The results strongly suggest that the two
