Propagation of Gravitational Waves in Chern-Simons Axion $F(R)$ Gravity

24 Feb 2020 Nojiri Shin'ichi Odintsov S. D. Oikonomou V. K. Popov Arkady A.

In this paper we shall study the evolution of cosmological gravitational waves in the context of Chern-Simons axion $F(R)$ gravity. In the case of Chern-Simons axion $F(R)$ gravity there exist spin-0, spin-2 and spin-1 modes... (read more)
