Highlights and Conclusions of the Chalonge Meudon Workshop Dark Matter
  in the Universe
  The CIAS Chalonge Workshop `Dark Matter in the Universe and Universal
Properties of Galaxies: Theory and Observations', was held at the Meudon
Ch^ateau of Observatoire de Paris on 8-11 June 2010. The Workshop approached DM
in a fourfold way: astronomical observations of DM structures (galaxy
properties, halos, rotation curves and density profiles), DM numerical
simulations (with and without baryons), theoretical astrophysics and cosmology
(kinetic theory, Boltzmann-Vlasov evolution), astroparticle physics. Peter
Biermann, Alfonso Cavaliere, Hector J. de Vega, Gianfranco Gentile, Chandra
Jog, Andrea Lapi, Paolo Salucci, Norma G. Sanchez, Pasquale Serpico, Rainer
Stiele, Janine van Eymeren and Markus Weber present here their highlights of
the Workshop. The summary and conclusions by H. J. de Vega and N. G. Sanchez
stress among other points the growing evidence that DM particles have a mass in
the keV scale and that those keV scale particles naturally produce the small
scale structures observed in galaxies. Wimps (DM particles heavier than 1 GeV)
are strongly disfavoured combining theory with galaxy astronomical
observations. Peter Biermann presents his live minutes of the Workshop and
concludes that a right-handed sterile neutrino of mass of a few keV is the most
interesting DM candidate. Photos of the Workshop are included.
