The Possibility Of The Dark Matter Celestial Body Existence And Detection

In this paper, we introduced the hot spot problem----dark matter, on the foundation ofcosmology development, and pointed out the dark matter is in the important position in thecosmos. Then we elaborated a few familiar dark matter models, and then fixed attention onthe F-W dark matter model and mirror dark matter model. The F-W dark matter model and inthe international called as mirror dark matter model are both put forward in the meantime andthere are two differences between them. One is the F–W dark matter model is on the theory ofa quantum field without divergence, but the mirror dark matter model is put forward forexplaining the dark matter phenomenon; two is that they have different proportion on the darkmatter and visible matter.The recent results of the experiment, just as the detection of"VIRGOHI21"and the"dwarf"galaxy around the Galaxy, are the direct proofs of discovered the cosmos darkgalaxy.The main works of this paper are that it points out that the W-matter can become a darkcelestial body, on the foundation of F-W dark matter model. And then give a possibleexplanation for the phenomena, the rotation curve of a spiral galaxy does not go down at verylarge radius and the hot gas radiated X-rays.It definitely showed that we can detect the dark matter celestial body, by observing therotation curve of a spiral galaxy, and the hot gas radiated X-rays, measuring a mass-to-lightratio, and the effect of gravitational lens. Finally we predict some huge cavities, in fact, arenot empty, and are galaxies or clusters of galaxies composed ofW-matter.We expect to use the F-W dark matter model explaining more phenomenon, and manymethods about detect dark matter celestial body will be put forward in the in future research.
