Dark Energy in Ghost-free non-local Gravity
S. D. Odintsov, V. K. Oikonomou, G. S. Sharov
Ghost-free non-local gravity is investigated with regards to its late-time dynamics. Viable solutions in this model are confronted with the observational data including the Pantheo…
Modified gravity/Dynamical Dark Energy vs CDM: is the game over?
Sergei D. Odintsov, Diego Sáez-Chillón Gómez, German S. Sharov
Over the last decades, tests on the standard model of cosmology, the so-called CDM model, have been widely analysed and compared with many different models for describing dark e…
Exponential gravity with logarithmic corrections in the presence of axion dark matter
Sergei D. Odintsov, Diego Sáez-Chillón Gómez, German S. Sharov
An exponential modified gravity with additional logarithmic corrections is considered with the presence of an axion-like scalar field in the role of dark matter. Axion fields are t…
Exponential F(R) gravity with axion dark matter
Sergei D. Odintsov, Diego Sáez-Chillón Gómez, German S. Sharov
The cosmological evolution within the framework of exponential gravity is analysed by assuming two forms for dark matter: (a) a standard dust-like fluid and (b) an axion sca…
Early Dark Energy with Power-law F(R) Gravity
Sergei D. Odintsov, V. K. Oikonomou, German S. Sharov
We study a power-law gravity with an early dark energy term, that can describe both the early-time and the late-time acceleration of the Universe. We confront this scenario…
Testing viable extensions of Einstein-Gauss-Bonnet gravity
Sergei D. Odintsov, Diego Saez-Chillon Gomez, German S. Sharov
Some models within the framework of Gauss-Bonnet gravities are considered in the presence of a non-minimally coupled scalar field. By imposing a particular constraint on the scalar…
