Tracing Inflationary Imprints Through the Dark Ages: Implications for Early Stars and Galaxies Formation
K. El Bourakadi, M. Yu. Khlopov, M. Krasnov +2
We explore how inflationary features shape the early stages of cosmic structure formation. Using the transfer function formalism, we trace the evolution of primordial perturbations…
Signatures of the Early Universe: Uncovering Cosmological Footprints
K. El Bourakadi, Z. Sakhi, M. Bennai
The post-inflationary epochs are critical for comprehending the early evolution of our Universe. This article delves into the cosmological signatures that shed light on these early…
Observational constraints on Tachyon inflation and reheating in f(Q) gravity
K. El Bourakadi, Z. Sakhi, M. Bennai
In this work we study one of the most appealing string theory-motivated models, we present a tachyonic inflationary model in the recently proposed symmetric teleparallel framework,…
Preheating constraints in -attractor inflation and Gravitational Waves production
K. El Bourakadi, Z. Sakhi, M. Bennai
We propose a scenario where preheating occurs for a specific duration that is parametrized by an e-folds number , our results suggest a direct correlation between the preh…
Gravitational Waves from Preheating in Gauss-Bonnet Inflation
K. El Bourakadi, M. Ferricha-Alami, H. Filali +2
We study gravitational wave production in an expanding Universe during the first stages following inflation, and investigate the consequences of the Gauss-Bonnet term on the inflat…
A new unified model of dark matter and dark energy in 5-dimensional gravity
M. Bousder, Z. Sakhi, M. Bennai
We propose a new unified model that describes~dark energy and dark matter in the context of gravity using a massive scalar field in five dimensions. The scalar field is co…
On Inflation Potentials in Randall-Sundrum Braneworld Model
M. Bennai, H. Chakir, Z. Sakhi
We study the inflationary dynamics of the universe in the Randall-Sandrum typeII Braneworld model. We consider both an inverse-power law and exponential potentials and apply the Sl…
