Candidatos à matéria escura no universo: MACHOs e WIMPs.

Abstract

An enigma we observe in contemporaneity is the discrepancy between the total mass predicted by the Law of gravity of Newton or Einstein and the total mass observed in the Universe. As much of the content that makes up the Universe consists of something not yet determined and that does not emit luminosity, which is called Dark Matter (M E). There are some proposed paths that attempt to explain this deviation from the theoretical prediction. The proposal of the existence of dark matter is observed from the appearance of some candidates who can explain them, however, has not yet been observed directly. In this dissertation, we will present a theoretical review of the candidate ME models emphasizing the MACHO (Massive Compact Halo Object), weakly interacting massive particles (WIMPs) and the perspectives of the LIGO as support for the confirmation of the existence of the ME.
