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

open access: yes
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.

Dark Matter Structures in the Universe: Prospects for Optical Astronomy in the Next Decade

open access: yes, 2009
The Cold Dark Matter theory of gravitationally-driven hierarchical structure formation has earned its status as a paradigm by explaining the distribution of matter over large spans of cosmic distance and time. However, its central tenet, that most of the

Unified Radial Distributions of Dark Matter

open access: yes
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

open access: yesEuropean 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

open access: yesEuropean 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,

Stimulated emission of dark matter via thermal scattering: novel limits for freeze-in and eV cold dark matter

open access: yesJournal of High Energy Physics
Recently, one of the present authors noticed a stimulated emission process of bosonic dark matter via the two-body decay of a mother particle in a thermal plasma similar to the operation principle of a laser in [1]. In this paper, we show that in a 2 → 2
