Project description

Our team has analysed the very relaxed cluster, Abell 496, known to be very regular both at X-ray and optical wavelengths, and also from a dynamical point of view. Our data cover a field of view that is wide enough to reach the virial radius and thus probe a variety of environments. Our general motivation was to obtain LFs in various regions of Abell 496 and compare them with previous works.

Project description

The Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) is a large multi-color survey conducted with the wide field optical imaging camera MegaCam at CFHT. The data were taken in 5 filters (u*, g, r, i, z) and cover 155 square degrees in four different fields (W1, W2, W3, W4). The photometric redshifts are derived for millions of sources and are based on the final public data release T007 of the CFHTLS-Wide catalogues delivered by Terapix.

The ‘Herschel Reference Survey’ (HRS, Boselli et al., 2010) is a guaranteed time Herschel key project and will be a benchmark study of dust in the nearby universe. The survey will complement a number of other Herschel key projects including large cosmological surveys that trace dust in the distant universe.
In addition to Herschel data, HRS provides ancillary data for its targets.

Project description

The Cosmological Evolution Survey (COSMOS) is an astronomical survey designed to probe the formation and evolution of galaxies as a function of cosmic time (redshift) and large scale structure environment.
The survey covers a 2 square degree equatorial field with imaging by most of the major space based telescopes (Hubble, Spitzer, GALEX, XMM, Chandra) and a number of large ground based telescopes (Subaru, VLA, ESO-VLT, UKRIT, NOAO, CFHT and others).
Over 2 million galaxies are detected, spanning 75% of the age of the universe.
The COSMOS survey involves almost 100 scientists in a dozen countries.

Project description

UltraVISTA is an Ultra Deep, near-infrared survey with the new VISTA survey telescope of the European Southern Observatory (ESO). Over the course of several years, UltraVISTA will repeatedly image the COSMOS field in 5 bands resulting in three key surveys:
– an ultra-deep broad-band (Y, J, H, Ks) survey (1408hr) covering 0.73 deg²
– a deep broad-band (Y, J, H, Ks) survey (212hr) covering the full 1.5deg² field
– a narrow-band (180hr) survey covering the same region as the ultra-deep broad-band survey

Project description

VIPERS Multi-Lambda Survey (VIPERS-MLS, PI: S. Arnouts) aims at providing photometry in the ultraviolet and Near Infrared wavelengths in the two regions observed by the VIMOS Public Extragalactic Redshift Survey (VIPERS, carried out at the VLT). The VIPERS-MLS NIR depth has been adjusted to guarantee an almost complete detection of the majority of the 100,000 spectroscopic high-z galaxies (with iAB<22.5). By combining with the NUV photometry from the GALEX Deep Imaging Survey (Texp=20-30ksec), we can assess reliable physical properties (SFR, dust, stellar masses) for most of the VIPERS sources. The original motivation is to investigate the evolution of galaxy properties within the cosmic web at high redshift as traced by VIPERS. <br>Beyond the VIPERS spectroscopic redshift, this unique multi-wavelength sample enable us to derive reliable photometric redshifts and physical properties for a few millions of sources. The large cosmological volume (0.< z <1.5) is ideal to analyze the evolution of galaxy clustering, weak lensing and environmental effects as a function of galaxy properties and to constrain the evolution of the stellar mass function of massive galaxies.

The XMM-LSS Survey is one of the largest deep cluster survey to date. Extensive coverage exists from X-ray to radio wavelengths over the 11 deg2 area. The survey enables the detection of clusters (M~1014Mo) well above z>1. Special care has been devoted to the characterization of the survey selection function and, to date, the XMM-LSS cluster sample is the only published sample of XMM serendipitous clusters with well-modelled selection criteria.<p>The project has not yet made public data available.
