The Big Bang: Origins and initial conditions from Self-Regulating Cosmology (SRC) model
Manasse R. Mbonye
Generating appropriate initial conditions for the Universe is key to discussing cosmic evolution constructively. In standard cosmology the traditional approach assumes an early Uni…
On covariant perturbations with scalar field in modified Gauss-Bonnet gravity
Albert Munyeshyaka, Joseph Ntahompagaze, Tom Mutabazi +1
We investigate cosmological perturbations of f(G) gravity in the presence of a scalar field. Using the 1 + 3 covariant formalism, we present the energy overdensity perturbation equ…
Is cosmic dynamics self-regulating?
Manasse R. Mbonye
In this paper we discuss a cosmological model for a universe with self-regulating features. We set up the theoretical framework for the model and determine the time evolution of th…
Perturbations in the interacting vacuum
Albert Munyeshyaka, Joseph Ntahompagaze, Tom Mutabazi +4
In this study, we present the evolution of cosmological perturbations in a universe consisting of standard matter and interacting vacuum. We use the covariant formalism in…
Large-scale structure power spectrum from scalar-tensor gravity
Joseph Ntahompagaze, Amare Abebe, Manasse R. Mbonye
This work deals with the computation of the power spectrum of large-scale structure using the dynamical system approach for a multi-fluid universe in scalar-tensor theory of gravit…
On multifluid perturbations in scalar-tensor cosmology
Joseph Ntahompagaze, Shambel Sahlu, Amare Abebe +1
In this paper the scalar-tensor theory is applied to the study of perturbations in a multi-fluid universe, using the 1+3 covariant approach. Both scalar and harmonic decompositions…
