A Dark Energy Paradigm: III. Unified Dark Sector to Predict Dark Energy, Dark Matter, and Baryonic Matter Distributions

Abstract A dark energy paradigm was first developed by authors to solve the cosmological constant problem and to predict lepton masses as evidence. It was used to reveal an underlying structure of a M ON D algorithm to model cold dark matter and to predict galactic dynamics.

Unified Radial Distributions of Dark Matter

The factorization of the radial distance of different galaxies into a galaxy dependent factor and a dark matter dependent factor is presented. Using the dark matter dependent factor, dark matter properties can be investigated independent of the mass and size of the different galaxies.

Quasinormal modes of Schwarzschild black holes in the Dehnen-(1, 4, 5/2) type dark matter halos

European Physical Journal C: Particles and Fields
The Dehnen-type dark matter density distribution model is mainly used for dwarf galaxies. In recent years, researchers have speculated that black holes may exist in this dark matter model and have given the black hole metric solutions.

Probing black holes via quasinormal modes in a dark energy-induced dark matter

European Physical Journal C: Particles and Fields
This study delves into the existence of dark matter around supermassive black holes in galactic cores using a novel gravitational model. By analyzing gravitational waves emitted during the ringdown phase of black holes under different field perturbations,
