We propose helium-4 spallation processes induced by long-lived
stau in supersymmetric standard models, and investigate an
impact of the processes on light elements abundances.
We show that, as long as the phase space of helium-4 spallation
processes is open, they are more important than stau-catalyzed
fusion and hence constrain the stau property.

If the Universe reionizes in patches, the observed optical depth \tau varies with the line of sight. Scattering of CMB photons by free electrons results in a damping of the CMB power spectra by a factor exp(-2\tau). When the optical depth is anisotropic, the damping has an angular dependence. We show that this angular dependence adds power to the CMB TT spectrum on small scales. We use data from

The current paradigm of structure formation predicts the existence of sub-galactic structures which existence has not been confirmed nor excluded by astrophysical observations. Some of these substructures could be disrupted by tidal interactions with other galaxy components, leading to streams like structures. Whether subhalos or streams, the presence of these dark matter structures in the solar n

High precision numerical simulations of the Lambda Cold Dark Matter (LCDM) model seem to coincide very well with astronomical observations of galaxies and clusters of galaxies. These dark matter simulations are more close to the Einasto profile in the centre of the galaxies and follow the Navarro-Frenk-White (NFW) one outside the centre. The coincidence is more accurate when the numerical simulat

We propose a new type of Dark Matter, the BDM, derived from particle gauge group theory, where the particles of BDM acaquier a large non-perturbative mass at a transtion scale Ec. The BDM particles are HDM above EC and CDM below this scale. BDM solves two of the main probelmosof CDM, namely the large number of substructure predicted by CDM and the core density porfile in the inner region of DM d
