Explores The Dark Matter With The Aid Of The Gravitational Lens Effect

On the foundation of reviewing the dark material survey process, this article studiedemphaticallysurveyedthedarkmaterialwiththeaidofthegravitationallensfunctionmethod.In our universe what we can detect the presence of the ordinary matter to the universe wasonly 4% of total energy, and the remaining 23 percent and 73 percent is the dark matter anddark energywhich were unable to directlydetected. Therefore, the final confirmation of a lotof dark matter and dark energy existing in the universe is of great significance. The earliermodel of dark matter is mainly baryon dark matter and non-baryon dark matter. And baryondarkmatterismainlyaxionandneutrino.This article also further narrated and commented theF-W model which proposed basedon the non-radiation quantum field theory's deduction and the mirror image dark materialmodelwhichproposedinternationallyinthesametime. Inordertorevealthemysteryoftheuniverse, scientists have adopted various detection methods to detect dark matter. Theexisting survey method mainly has the cluster, the X-ray method survey; Great criterionstructure observation; Direct surveyand with the aid of gravitational lens effect. This paperwill be mainly through gravitational lenses, respectively, the establishment of point-sourcemodel and the cluster model, to analyze the dark star and galaxy cluster in the detection ofdarkmatter.At last,this article respectively take the F-W dark star body, the baryon dark material aswell as the Abell2218 cluster of galaxies as the object of studing, has discussed its imageformationmodelandthecharacteristicasgravitationallens.
