The Chalonge School 15th Paris Cosmology Colloquium 2011 ” From Cold Dark Matter to Warm Dark Matter in the Standard Model of the Universe: Theory and Observations “

The International School Daniel Chalonge: 20 Years of Activity

The Conference is within the astrofundamental physics spirit of the Chalonge School, focalized on recent observational and theoretical progress on the CMB, dark matter, dark energy, dark ages, and the theory of the early universe with predictive power in the context of the Standard Model of the Universe.

Recently, LambdaWDM (Warm Dark Matter) emerged impressively over LambdaCDM (Cold Dark Matter) whose small -galactic- scale (and even larger scale) problems are ever-increasing. LambdaWDM solves naturally the problems of LambdaCDM and agree with the observations at small as well as large and cosmological scales.

In summary, the aim of the meeting is to put together the recent cosmological and astrophysical data and hard theory predictive approach connected to them in the framework of the Standard Model of the Universe.

TOPICS:

Observational and theoretical progress on the nature of dark matter: keV scale dark matter particles.
Dark energy: cosmological constant: the quantum energy of the cosmological vacuum.
Large and small scale structure formation in agreement with observations at large scales and small (galactic) scales.
The ever increasing problems of LambdaCDM.
The emergence of Warm (keV scale) Dark Matter from theory and observations.
The analysis of the CMB+LSS+SN data with the effective (Ginsburg-Landau) effective theory of inflation: New Inflation (double well inflaton potential) strongly favored by the CMB + LSS + SN data: The presence of the lower bound for the primordial gravitons (non vanishing tensor to scalar ratio r) with the present CMB + LSS + SN data. CMB polarization and forecasts for Planck.
Neutrinos in cosmology.
The new serious dark matter candidate: Sterile neutrinos at the keV scale.

All Lectures are followed by a discussion. All participants are invited to take part in the discussions.

The Meeting is open to all scientists interested in the subject but Registration is mandatory.

The format of the Meeting is intended to allow easy and fruitful mutual contact and communication.

Sessions last for three full days in the beautiful parisian campus of Observatoire de Paris (built on orders from Colbert and to plans by Claude Perrault from 1667 to 1672). All sessions take place at the Salle Cassini (Cassini Hall) in the historic Perrault building (“Bâtiment Perrault”) of Observatoire de Paris HQ. All Coffee-Tea breaks take place at the “Salle du Conseil” under the portraits of Laplace, Le Verrier, Lalande, Arago, Delambre and Louis XIV. The Registration desk and the Secretariat of the Colloquium take place at the “Grande Galerie” (Great Gallery) just aside facing Salle du Conseil

EXHIBITION:

An exhibition at the “Grand Galerie” (Great Gallery) and “Salle Cassini” (Cassini Hall) will retrace the 20 years of activity of the Chalonge School and “The Golden Days” in “Astrofundamental Physics”: The Construction of the Standard Model Of the Universe, as well as the Exhibition “The World High Altitude Observatories Network: World Cultural and Scientific Heritage”.

The books and proceedings of the School since its creation, as well as historic Daniel Chalonge material, Prizes and Chalonge instruments will be on exhibition at the Great Gallery.
