Spherically Symmetric Solutions in F(R) Gravity and Gravitational Repulsion
E. V. Arbuzova, A. D. Dolgov, L. Reverberi
Spherically symmetric solutions in F(R) theories in astronomical systems with rising energy density are studied. The range of parameters is established for which the flat space-tim…

Particle Production in f(R) Gravity during Structure Formation
E. V. Arbuzova, A. D. Dolgov, L. Reverberi
We study particle production in infrared-modified gravitational theories in the contemporary universe. It is shown that in astronomical systems with rising mass density, the curvat…
