Highlights and Conclusions
A Turning Point in the Research of Dark Matter: Warm Dark
Matter. Theory and Observations 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.
The Workshop addresses the last progresses made in Warm Dark Matter and the Universal and Non Universal properties of Galaxies. In the tradition of the Chalonge School, an effort of clarification and synthesis will be made by combining in a conceptual framework, theory, analytical, observational and numerical simulation results. The subject will be approached in a threefold way:
(I) Conceptual context: Dark Matter in cosmology and astrophysics: perspective and prospective of the research in the subject: Theory and observations. The emergence of Warm (keV scale) Dark Matter from theory and observations.
(II) Astronomical observations linked to the galaxy structural properties and especially to the universal and non universal properties of galaxies: high quality rotation curves, kinematics, density profiles, gravitational lensing, small and large structures.
(III) Numerical simulations with Warm Dark Matter , large structures, structures and substructures.
Special attention will be payed to the astrophysical understanding of the dark matter problems, the use of analytic and numerical methods which determine the properties, the distribution and the nature of Warm Dark Matter.
FORMAT: All Lectures are followed by a discussion. All participants are invited to take part in the discussions.
Enough time will be available for the discussions.
The Meeting is open to all scientists interested in the subject. Registration is mandatory. Registration information is given below.
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 and green Meudon campus of Observatoire de Paris in the historic Castle with the Great Dome building ("Château Grande Coupole") where CIAS (Centre International d´ Ateliers Scientifiques) is located.
All lectures and presentations will take place at the Castle Conference Room (Salle de Conferences du Château) in the historic Castle building.
All Coffee-Tea breaks will take place at the Urania Hall aside the castle conference room in the same building. The Registration desk and the Secretariat of the Workshop take place at the Urania Hall.
Discussions and working sessions all during the workshop will take place at the CIAS rooms aside the Urania Hall.

Longitude : 2° 14' East . Latitude : 48° 48' North . Altitude : 162m
Meudon Observatory is located Place Jules Janssen , in Meudon at the top of the Avenue du Château.
By train. The best way for visitors to reach Meudon Observatory is from Paris-Montparnasse train station and to stop at Bellevue station (recommended stop). The travel duration by train from Paris Montparnasse to Bellevue station is about 12 minutes. Recommended way is the following:
By train (French railways - SNCF): At Paris-Montparnasse station, take the train going to Sèvres or to Versailles-Chantiers, Rambouillet, Chartres, (which frequency is every 15 min.). Make sure that the train stops at the Meudon or Bellevue stations. Get out at the 4th station: Bellevue (after Vanves-Malakoff, Clamart and Meudon stations).
Once outside Bellevue station, turn left (passing the church aside the station) and take the green Avenue du Château bordered by trees: the entrance of the Observatory is on the top of the hill. About a 10/15 minutes walk to reach the gates of the Observatory. [There is also a mini bus (circular local line) from the Bellevue station to the Observatory].
If you stop at the Meudon station: outside the station, turn to the right, after 200 m turn again to the right to take avenue Corbeiller [where the Meudon Municipality is located (Mairie de Meudon), ahead up to the top of the hill along avenue Corbeiller, rue Jacqueminot lined with stately chestnut trees.
Once arrived, use the map of the Observatory campus: Chateau Grande Coupole CIAS where the meeting takes place, (building 9 in the map) is on the terrasse (take the staircase in the garden at the left after the entry and then at the left straight on the road along the terrasse bordered by the chestnut trees.
By car there are 2 possible routes : Take the périphérique, exit at Quai d Issy, then go towards Issy les Moulineaux, Sèvres and finally Meudon Take N 118, from the Pont de Sèvres, going towards Chartres Orléans, exiting at Meudon Sèvres and then going towards Meudon.

THE PARIS OBSERVATORY AT MEUDON : A BRIEF HISTORY
At present the Observatoire de Paris owns three campuses: Paris, Meudon and the radioastronomy station at Nançay. More than 700 scientists, technicians and administrative staff work there.
The history of the present Meudon Castle (Château de Meudon) starts several centuries ago.
The new Château de Meudon over where the cupola of the Meudon Observatory is installed was built in 1706 by the great architect Jules-Hardouin Mansart in orders by King Louis XIV for his son the Grand Dauphin. This was the last important project realized by Mansart. The gardens and water fontaines were constructed under the plans by Le Nôtre. Important visitors stayed in the Château de Meudon in the XVIII century as the Zar of Russia Peter the Great and the King of Poland Stanislas Leszczyski.
After the French Revolution, a workshop to construct military balloons was settled in the area. These balloons played an important rôle in the Fleurus battle against Austria in 1794. Napoleon restaured the Château de Meudon and the Empress Marie-Louise and their son (the King of Rome) lived in the Castle.
The terrasse was used by the prussians to shell Paris during the siege of 1870. The Château de Meudon took fire at that time.
In 1876 the astronomer Jules Janssen created the Meudon Observatory and in 1893 a refraction telescope was installed over in the Castle.
