On the perturbed Friedmann equations in Newtonian Gauge
Jaume de Haro, Emilio Elizalde, Supriya Pan
Based on the Newtonian mechanics, in this article, we present a heuristic derivation of the Friedmann equations, providing an intuitive foundation for these fundamental relations i…
Holographic bounce cosmological models induced by viscous dark fluid from a generalized non-singular entropy function
E. Elizalde, A. V. Yurov, A. V. Timoshkin
Bounce cosmological models containing a dark viscous fluid in a spatially flat Friedmann-Robertson-Walker (FRW) universe are considered. The universe evolution is described in term…
Can we learn from matter creation to solve the tension problem?
Emilio Elizalde, Martiros Khurshudyan, Sergei D. Odintsov
The tension problem is studied in the light of a matter creation mechanism (an effective approach to replacing dark energy), the way to define the matter creation rate bein…
Constraints on prospective deviations from the cold dark matter model using a Gaussian Process
Martiros Khurshudyan, Emilio Elizalde
Recently, using Bayesian Machine Learning, a deviation from the cold dark matter model on cosmological scales has been put forward. Such model might replace a proposed non-gravitat…
