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…
