A 12um ISOCAM Survey of the ESO-Sculptor Field: Data Reduction and Analysis
Nick Seymour, Brigitte Rocca-Volmerange, Valerie de Lapparent
We present a detailed reduction of a mid-infrared 12um (LW10 filter) ISOCAM open time observation performed on the ESO-Sculptor Survey field (Arnouts et al. 1997). A complete catal…
Towards a library of synthetic galaxy spectra and preliminary results of classification and parametrization of unresolved galaxies for Gaia
P. Tsalmantza, M. Kontizas, C. A. L. Bailer-Jones +8
Aims:The Gaia astrometric survey mission will, as a consequence of its scanning law, obtain low resolution optical (330-1000 nm) spectrophotometry of several million unresolved gal…
The 12um ISO-ESO-Sculptor and 24um Spitzer faint counts reveal a population of ULIRG/AGN/dusty massive ellipticals Evolution by types and cosmic star formation
B. Rocca-Volmerange, V. de Lapparent, N. Seymour +1
Multi-wavelength galaxy number counts provide clues on the nature of galaxy evolution. The interpretation per galaxy type with the new code PEGASE.3 of the 12mu (ISO) and 24mu (Spi…
Comparing dynamical and photometric-stellar masses of early-type galaxies at z ~ 1
A. Rettura, P. Rosati, V. Strazzullo +14
The purpose of this study is to explore the relationship between galaxy stellar masses, based on multiwavelength photometry spectral template fitting and dynamical masses based on…
Modelling and interpreting optical spectra of galaxies at R=10000
Ariane Lancon, Pierre Ocvirk, Damien Le Borgne +5
One way to extract more information from the integrated light of galaxies is to improve the spectral resolution at which observations and analysis are carried out. The population s…
Evidence of intense hot(~340K) dust in 3CR radio galaxies The most dissipative source of cooling in AGNs
B. Rocca-Volmerange, M. Remazeilles
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…
The European Large Area ISO Survey VIII: 90-micron final analysis and source counts
Ph. Heraudeau, S. Oliver, C. del Burgo +17
We present a re--analysis of the European Large Area ISO Survey (ELAIS) 90mum observations carried out with ISOPHOT, an instrument on board the ESA's Infrared Space Observatory (IS…
The radio galaxy K-z relation: the 10^12 Msol mass limit; masses of galaxies from the L_K luminosity, up to z >4
B. Rocca-Volmerange, D. Le Borgne, C. De Breuck +2
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 rang…
STELIB: a library of stellar spectra at R~2000
J. -F. Le Borgne, G. Bruzual, R. Pello +6
We present STELIB, a new spectroscopic stellar library, available at http://webast.ast.obs-mip.fr/stelib . STELIB consists of an homogeneous library of 249 stellar spectra in the v…
CO emission and associated HI absorption from a massive gas reservoir surrounding the z=3 radio galaxy B3 J2330+3927
Carlos De Breuck, Roberto Neri, Raffaella Morganti +10
We present results of a comprehensive multi-frequency study of the radio galaxy B3 J2330+3927. The 1.9" wide radio source, consisting of 3 components, is bracketed by 2 objects in…
The balance between shocks and AGN photoionization in radio sources and its relation to the radio size
E. Moy, B. Rocca-Volmerange
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…
The star formation history as a function of type: constraints from galaxy counts
Brigitte Rocca-Volmerange, Michel Fioc
Deep galaxy counts are among the best constraints on the cosmic star formation history (SFH) of galaxies. The evolution of the star formation activity is followed on a wide range o…
PEGASE.2, a metallicity-consistent spectral evolution model of galaxies: the documentation and the code
Michel Fioc, Brigitte Rocca-Volmerange
We provide here the documentation of the new version of the spectral evolution model PEGASE. PEGASE computes synthetic spectra of galaxies in the UV to near-IR range from 0 to 20 G…
UV rest frame spectroscopy of four high redshift (z>2) active galaxies
