Point mass Cosmological Black Holes
  Real black holes in the universe are located in the expanding accelerating
background which are called the cosmological black holes. Hence, it is
necessary to model these black holes in the cosmological background where the
dark energy is the dominant energy. In this paper, we argue that most of the
dynamical cosmological black holes can be modeled by point mass cosmological
black holes. Considering the de Sitter background for the accelerating
universe, we present the point mass cosmological background in the cosmological
de Sitter space time. Our work also includes the point mass black holes which
have charge and angular momentum. We study the mass, horizons, redshift
structure and geodesics properties for these black holes.
