EFFECTIVE COSMOLOGICAL CONSTANT IN BRANE COSMOLOGY

International Journal of Modern Physics D, 2006
We consider a brane-world of co-dimension one without reflection symmetry. Through it, we give a possible explanation of the great discrepancy between the vacuum energy and the observed cosmological constant without contradiction to the knowledge we have about our Universe. We also show the gravity observed will be standard four-dimensional gravity as

Cosmological simulations of galaxy formation

Nature Reviews Physics, 2019
Over recent decades, cosmological simulations of galaxy formation have been instrumental in advancing our understanding of structure and galaxy formation in the Universe.

Neutrinos in Cosmology

Progress in Particle and Nuclear Physics, 1988
About neutrinos, we only know that the three left handed \(\nu_{\rm e_{\rm{L}}}\ ,\ \nu_{\mu_{\rm{L}}}\ ,\ \nu_\tau\) exist, that they have weak interactions and that they are much lighter than their corresponding charged leptons. They may be massive or massless, stable or not.
