SUMMARY: 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
