CharlaIs Dark Matter the most valid explanation for the mass which is apparently missing in the Universe?
Two main families of models explain that, at least in appearance, something like 90% of the mass of the Universe is still undetected. One (supported by an...

PublicaciónLimiting the Abundance of LIGO/Virgo Black Holes with Microlensing Observations of Quasars of Finite Size
We present a simple but general argument that strongly limits the abundance of primordial black holes (PBHs) (or other unknown population of compact objects)...

PublicaciónLocal approximations to non-linear evolution of density fluctuations
The way in which the evaluation of any moment of the mass distribution, as given by the Zeldovich (1970) approximation, may be reduced to the computation of an...
