Scalar and vector perturbations in a universe with nonlinear perfect fluid
Ezgi Canay, Ruslan Brilenkov, Maxim Eingorn +2
We study a three-component universe filled with dust-like matter in the form of discrete inhomogeneities (e.g., galaxies) and perfect fluids characterized by linear and nonlinear e…
Formalizing Slow-roll Inflation in Scalar-Tensor Theories of Gravitation
Kemal Akın, A. Savaş Arapoğlu, A. Emrah Yükselci
The viability of slow-roll approximation is examined by considering the structure of phase spaces in scalar-tensor theories of gravitation and the analysis is exemplified with a no…
Neutron Star Structure in the Presence of Nonminimally Coupled Scalar Fields
A. Savaş Arapoğlu, K. Yavuz Ekşi, A. Emrah Yükselci
We study the structure of neutron stars in scalar-tensor theories for the nonminimal coupling of the form . We solve the hydrostatic equilibrium equations for tw…
