  Warm Dark Matter (WDM) research is progressing fast, the subject is new and
WDM essentially works, naturally reproducing the astronomical observations over
all scales: small (galactic) and large (cosmological) scales (LambdaWDM).
Evidence that Cold Dark Matter (LambdaCDM) and its proposed tailored cures do
not work at small scales is staggering. Fedor Bezrukov, Pier-Stefano
Corasaniti, Hector J. de Vega, Stefano Ettori, Frederic Hessmann, Ayuki Kamada,
Marco Lombardi, Alexander Merle, Christian Moni Bidin, Angelo Nucciotti on
behalf of the MARE collaboration, Sinziana Paduroiu, Henri Plana, Norma
Sanchez, Patrick Valageas, Shun Zhou present here their highlights of the
Workshop. LambdaWDM simulations with keV particles remarkably reproduce the
observations, small and large structures and velocity functions. Cored DM halos
and WDM are clearly determined from theory and astronomical observations, they
naturally produce the observed structures at all scales. keV sterile neutrinos
are the leading candidates, they naturally appear extensions of the standard
model of particle physics. Astrophysical constraints including Lyman alpha
bounds put its mass in the range 1< m <13 keV. Predictions for EUCLID and
PLANCK have been presented. MARE and an adapted KATRIN experiment could detect
a keV sterile neutrino. It will be a fantastic discovery to detect dark matter
in a beta decay. A formidable WDM work to perform is ahead of us, these
highlights point out some relevant research directions to put the effort.
Photos of the Workshop are included (Abridged).
