A multisite photometric campaign on the Pre-Main-Sequence delta Scuti pulsator IP Per
V. Ripepi, S. Bernabei, M. Marconi +18
We present the results of a photometric multisite campaign on the Scuti Pre-Main-Sequence star IP Per. Nine telescopes have been involved in the observations, with a total of a…
The Youngest Stellar clusters Clusters associated with massive protostellar candidates
M. S. N. Kumar, E. Keto, E. Clerkin
We report on the identification of 54 embedded clusters around 217 massive protostellar candidates of which 34 clusters are new detections. The embedded clusters are identified as…
The radio properties of the cD galaxy of Abell 2390
Pedro Augusto, Alastair C. Edge, Claire J. Chandler
We present multi-frequency, multi-epoch radio imaging of the complex radio source B2151+174 in the core of the cluster, Abell 2390 (z~0.23). From new and literature data we conclud…
Spectrophotometric properties of galaxies at intermediate redshifts (z ~ 0.2--1.0) II. The Luminosity -- Metallicity relation
Fabrice Lamareille, Thierry Contini, Jarle Brinchmann +3
We present the gas-phase oxygen abundance (O/H) for a sample of 131 star-forming galaxies at intermediate redshifts (). The sample selection, the spectroscopic observati…
Spectrophotometric properties of galaxies at intermediate redshifts (z ~ 0.2--1.0) I. Sample description, photometric properties and spectral measurements
Fabrice Lamareille, Thierry Contini, Jean-François Le Borgne +3
We present the spectrophotometric properties of a sample of 141 emission-line galaxies at redshifts in the range with a peak around . The analysis is bas…
Extracting Star Formation Histories from Medium-resolution Galaxy Spectra
Hugues Mathis, Stephane Charlot, Jarle Brinchmann
We adapt an existing data compression algorithm, MOPED, to the extraction of median-likelihood star formation (SF) histories from medium-resolution galaxy spectra. By focusing on t…
An unbiased search for the signatures of protostars in the rho Ophiuchi Molecular Cloud. II. Millimetre continuum observations
Thomas Stanke, Michael D. Smith, Roland Gredel +1
We have performed a 1 square degree 1.2mm dust continuum survey in the rho Oph molecular cloud. We detect a number of previously unknown sources, ranging from extended cores over c…
Trends in Space Astronomy and Cosmic Vision 2015-2025
Catherine Turon, Chris Done, Andreas Quirrenbach +14
As a short introduction to the astronomy session, the response of the community to the Call for Themes issued by ESA and the specific themes selected by the Astronomy Working Group…
A mean redshift of 2.8 for Swift gamma-ray bursts
P. Jakobsson, A. Levan, J. P. U. Fynbo +18
The exceptionally high luminosities of gamma-ray bursts (GRBs), gradually emerging as extremely useful probes of star formation, make them promising tools for exploration of the hi…
Disk and wind interaction in the young stellar object MWC 297 spatially resolved with VLTI/AMBER
F. Malbet, M. Benisty, W. J. De Wit +15
The young stellar object MWC 297 has been observed with the VLT interferometer equipped with the AMBER instrument. MWC 297 has been spatially resolved in the continuum with a visib…
The Fourth Data Release of the Sloan Digital Sky Survey
J. K. Adelman-McCarthy et al.
This paper describes the fourth data release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through June 2004. The data release includes five-band…
VITRUV - Science Cases
Paulo J. V. Garcia, Jean-Phillipe Berger, Romano Corradi +11
VITRUV is a second generation spectro-imager for the PRIMA enabled Very Large Telescope Interferometer. By combining simultaneously up to 8 telescopes VITRUV makes the VLTI up to 6…
VITRUV - Imaging close environments of stars and galaxies with the VLTI at milli-arcsec resolution
Fabien Malbet, Jean-Philippe Berger, Paulo Garcia +11
The VITRUV project has the objective to deliver milli-arcsecond spectro-images of the environment of compact sources like young stars, active galaxies and evolved stars to the comm…
The ages and metallicities of galaxies in the local universe
Anna Gallazzi, Stephane Charlot, Jarle Brinchmann +2
We derive stellar metallicities, light-weighted ages and stellar masses for a magnitude-limited sample of 175,128 galaxies drawn from the Sloan Digital Sky Survey Data Release Two…
Seismic analysis of the second ionization region of helium in the Sun: I. Sensitivity study and methodology
M. J. P. F. G. Monteiro, M. J. Thompson
The region of the second ionization of helium in the Sun is a narrow layer near the surface. Ionization induces a local change of the adiabatic exponent , which produces a cha…
The host galaxies of radio-loud AGN: mass dependencies, gas cooling and AGN feedback
P. N. Best, G. Kauffmann, T. M. Heckman +4
The properties of the host galaxies of a well-defined sample of 2215 radio-loud AGN with redshifts 0.03 < z < 0.3, defined from the SDSS, are investigated. These are predominantly…
Number counts in homogeneous and inhomogeneous dark energy models
N. J. Nunes, A. C. da Silva, N. Aghanim
In the simple case of a constant equation of state, redshift distribution of collapsed structures may constrain dark energy models. Different dark energy models having the same ene…
