The cosmic web formed by the large-scale structure of the Universe is a subject of intense study covering the entire electromagnetic spectrum.  The evolution of cosmic structure is uniquely relevant for cosmological studies as it reveals the the physics of gravitational growth since the big bang.  Hot and energetic extragalactic sources, namely clusters of galaxies and active galactic nuclei (AGN), play a key role as tracers of deep gravitational potentials and revel many aspects of gravitational physics.
Galaxy clusters and AGN are luminous sources of energetic X-ray photons and X-ray observations provide a highly effective means of identifying such sources.  Since the launch of the Chandra and XMM-Newton observatories in 1999, our knowledge of clusters and AGN out to cosmological distances has been transformed.  This period has also witnessed great advances in the scale and complexity of numerical simulations of galaxy clusters and supermassive black holes - from the details of individual systems to their cosmological context.

The community is currently facing the challenge of applying large surveys of galaxy clusters and AGN as precision probes of our cosmological model.

Considering the probable extension of the XMM mission for another twelve years, the meeting aims at (1) a review of the state-of-the art studies of the cosmic web, as revealed in X-rays in partnership with observations across the entire electromagnetic spectrum; (2) providing a framework to discuss holistic pictures of structure formation with the aid of numerical simulations; (3) exploring the scientific potential and feasibility of future extra-large, community-based surveys with XMM.
One of the meeting highlights will be the presentation of recent results from the XXL survey, the largest XMM programme undertaken to date (6 Ms ­ 2x25 sq. deg. - with some 500 clusters of galaxies and 25,000 AGNs).
The meeting will adopt a workshop format allowing for focused presentations, round-table discussions and free time for informal discussions.
