摘要
The dark matter and dark energy dominate the behavior of our universe. Theunknown dark matter usually forms halos in large number of galaxies. Propertiesof dark matter halo can be revealed and understood from the gravitationallensing observations. In this work, a comprehensive study on the weakgravitational lensing of black hole embedded in dark matter halos is presented.To effectively model the supermassive black hole in galaxy center (which issurrounded by dark matter halo) in a simple way, we use the Schwarzschild blackhole and charged Reissner-Nordstr\"om black hole embedded in a perfect fluiddark matter halo. In the present work, several key quantities in weakgravitational lensing (gravitational deflection angle of light, photon sphere,black hole shadow radius, gravitational lens equation and Einstein ring) arecalculated and analyzed analytically and numerically. The results in our workindicate that the dark matter can greatly influence the gravitational lensingof central black holes.
