Chalonge School CIAS Workshop 2011 “Warm Dark Matter in Galaxies: Theoretical and Observational Progresses”
Ecole Internationale Daniel Chalonge
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 agrees 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 that reproduce observations.The subject will be approached in a threefold way: (I) Conceptual context. (II) Astronomical observations linked to the galaxy structural properties and to structure formation at different (large and small (galactic) scales). (III) Numerical simulations which reproduce observations at large and small (galactic) scales.
Recent progress in solving the Boltzmann-Vlasov equation to obtain the observed properties of galaxies (and clusters of galaxies). N-body numerical simulations with Warm Dark Matter.The surface density . The phase-space density. Particle model independent analysis of astrophysical dark matter. The impact of the mass of the dark matter particle on the small scale structure formation. The radial profiles and the Dark Matter distribution. Cores versus Cusps. The ever increasing problems of LambdaCDM. The keV scale Dark Matter (Warm Dark Matter): Observational and theoretical progresses. Large and small scale structure formation in agreement with observations at large and small (galactic) scales. The new serious dark matter candidate: Sterile neutrinos at the keV scale.
Sessions last for three full days in the beautiful Meudon campus of Observatoire de Paris, where CIAS “Centre International d´Ateliers Scientifiques” is located. All sessions take place in the historic Château building, (built in 1706 by great architect Jules-Hardouin Mansart in orders by King Louis XIV for his son the Grand Dauphin). The Meeting is open to all scientists interested in the subject. The format of the Meeting is intended to allow easy and fruitful mutual contact and communication. Informations about the Workshop, participation information and background information are displayed at the http://www.chalonge.obspm.fr/Cias_Meudon2011.html
Early Registration is strongly encouraged
