Tsallis Holographic Dark Energy model with varying gravitational constant vs CDM model: statistical analysis of observational data and tensions problem
Artyom V. Astashenok, Alexander S. Tepliakov
We investigate the cosmological evolution of a flat Friedmann--Robertson--Walker Universe filled with Tsallis holographic dark energy (THDE) under the assumption that the gravitati…
Non-flat Universe with Tsallis holographic dark energy
Artyom V. Astashenok, Alexander S. Tepliakov
We investigated evolution of metric and density perturbations for Tsallis model of holographic dark energy with energy density , where is length of event horizo…
General constraints on Tsallis holographic dark energy from observational data
Artyom V. Astashenok, Alexander S. Tepliakov
We investigated Tsallis holographic dark energy (THDE) model in light of modern observations of supernovae, Hubble parameter measurements, data for baryon acoustic oscillations and…
Evolution of perturbations in the model of Tsallis holographic dark energy
Artyom V. Astashenok, Alexander S. Tepliakov
We investigated evolution of metric and density perturbations for Tsallis model of holographic dark energy with energy density , where is length of event horizo…
Compact Stars with Dark Energy in General Relativity and Modified Gravity
Artyom V. Astashenok, Sergey D. Odintsov, Vasilis K. Oikonomou
We investigate realistic models of compact objects, focusing on neutron and strange stars, composed by dense matter and dark energy in the form of a simple fluid or scalar field in…
Dynamical analysis of the Tsallis holographic dark energy models with event horizon as cut-off and interaction with matter
A. V. Astashenok, A. S. Tepliakov
The model of generalized Tsallis holographic dark energy (which is known to be particular representative of Nojiri-Odintsov HDE) with event horizon as cut-off is investigated using…
