Tableau de de Vassily Kandinsky qui apparait comme un visionnaire: - le cercle représente le champ de vue d'XMM - le grand X, représente "rayons X" et symbolise les digrammes cosmologiques - les cercles de différentes couleurs: les amas de galaxies vus en rayons X avec des temperatures différentes - les petits points: les noyaux actifs de galaxies vus en rayons X - les grands traits noirs fins: les grandes structure de l'univers |
The XXL survey has mapped two extragalactic regions of 25 deg2, using 10 ks XMM observations down to a point-source sensitivity of ~ 5 10-15 erg/s/cm2 in the [0.5-2] keV band.
It is the largest XMM project approved to date (3Ms in December 2010, >6Ms in total).
As of December 2015, some 450 new galaxy clusters are detected out to z~1.5-2 as well as more than 22,000 active galactic nuclei (AGNs) out to z~4.
The main goal of the project is to constrain the Dark Energy equation of state using clusters of galaxies. This survey will also have lasting legacy value for cluster scaling laws and studies of AGNs and X-ray background.
This project builds on the experience acquired during the ten years XMM-LSS pilot survey. It is open to any scientist belonging to the international astronomical community, and interested in actively contributing to the general legacy effort.
The two surveyed regions are:
-
CFHTLS W1 centre: 2h23min -4deg30' (J2000), 25 deg2
-
BCS centre: 23h30min -55deg00' (J2000), 25 deg2
Observations were completed in 2013
The XXL exposure ans sensitivity maps are available here

The three-dimensional visualization of redshift surveys is a key player in the comprehension of the structuration of the cosmic web. The SDvision software package, intended primarily for the visualization of massive cosmological simulations, has been extended to provide an interactive visual representation of different classes of redshift surveys, with the objective to enable direct comparisons between the rare highest-density peaks traced by the clusters of galaxies found in the XMM-LSS Survey and the densely populated catalogues of galaxy photometric redshifts. We present the various possibilities offered by this tool in terms of filtering of the data, reconstruction of density fields, interactivity and visual rendering, including various techniques such as ray-casting, isosurfaces, slicing and texturing. This is illustrated using the C1 and C2 samples of the XMM-LSS Survey, and the publicly released COSMOS and CFHTLS photometric redshift Catalogs. Comparisons with published results are presented and discussed. (download pdf)
Any scientist is welcome to enter the consortium in order to participate in the data analysis and science activities. Privileged access to the entire XXL data set will be granted to all consortium members.

XXL is an international project based around an XMM Very Large Programme surveying two 25 deg2 extragalactic fields at a depth of ~6 x 10-15 erg cm-2 s-1 in the [0.5-2] keV band for point-like sources. The XXL website is http://irfu.cea.fr/xxl. Multi-band information and spectroscopic follow-up of the X-ray sources are obtained through a number of survey programmes, summarised at http://xxlmultiwave.pbworks.com/.
