We demonstrate through the use of a simple toy model that asphericity in dark matter halos has a measurable effect on the configuration dependence of the weak lensing shear 3-point function at small scales. This sensitivity provides a way, in principle, to measure the shapes of dark matter halos. The distribution of halo ellipticities should be included in models aiming at a high fidelity predi...

The ANTARES collaboration is building a deep underwater neutrino Cerenkov telescope at 2400 m which will be located off the Mediterranean sea coast near Toulon, France. The main scientific aims of the experiment are the detection of high energy upgoing muons coming from astrophysical neutrinos, indirect dark matter searches, the study of atmospheric neutrino oscillations. The detector will be c...

Uncompactified KK universes are so intrinsically connected to the otherwise only empirically required “missing” Dark Matter (DM),

Recent cosmological data allow to determine the universal Dark Matter (DM) density to a precision of about 10%, if a simple, well–motivated ansatz for the spectrum of primordial density perturbations is correct. Not surprisingly, a thermal neutralinõ χ 0 1 will have the correct relic density only in " small " regions of parameter space. In particular, for fixed values of the other parameters, t...

We present a new technique developed for the measurement of the scintillation efficiency of nuclear recoils in solid scintillators. Using this technique we measured the quenching of the scintillation efficiency for the various recoiling nuclei in CaWO4 crystals which are used in direct Dark Matter searches.

The claim that large-scale structure data independently prefers the Λ Cold Dark Matter model is a myth. However, an updated compilation of large-scale structure observations cannot rule out ΛCDM at 95% confidence. We explore the possibility of improving the model by adding Hot Dark Matter but the fit becomes worse; this allows us to set limits on the neutrino mass.
