Coupled quintessence and the impossibility of an interaction: a dynamical analysis study

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We analyze the coupled quintessence in the light of the linear dynamical systems theory, with two different interactions: (1) proportional to the energy density of the dark energy and (2) proportional to the sum of the energy densities of the dark matter

Constraining Extended Teleparallel Gravity via Cosmography: A Model-independent Approach

open access: yesThe Astrophysical Journal
As a classical approach, the dynamics of the Universe, influenced by its dark components, are unveiled through prior modifications of Einstein’s equations.

Dark Energy or just Energy?

open access: yes, 2019
This research note hypothesizes new physics without dark energy, dark matter, extra dimensions, or deviation from proven mathematical models. The main assumption is that matter expands proportionally with space, and that the proposed discrete step-expansion of the elementary particles may provide a platform for unification of the four fundamental ...
