Models with Non-minimal Coupling in Primordial Universe and Cosmological Observations
Alireza Talebian, Hassan Firouzjahi, Fereshteh Felegary
A non-minimal coupling between gravity and the inflaton field is a generic contribution in inflationary cosmology. In this work, we consider models of inflation with a non-minimal…
k-inflation: Non-separable case meets ACT measurements
Tahere Fallahi Serish, Seyed Ali Hosseini Mansoori, Fereshteh Felegary +2
We investigate a non-separable subset of -essence in which the kinetic and potential sectors interact through an coupling, implemented via a potential-dependent prefac…
Probing single-field inflation: predictions, constraints, and theoretical viewpoints
Fereshteh Felegary, Thammarong Eadkhong, Farruh Atamurotov +1
This work investigates a single-field inflationary model, a specific class of the K-essence models where a coupling term exists between canonical Lagrangian and the potential. This…
Tilt and Tensor-to-Scalar Ratio in Multi-Scalar Field Inflation: Non-Sum-Separable Case
Fereshteh Felegary, Seyed Ali Hosseini Mansoori, Tahere Fallahi Serish +1
The canonical multi-scalar field inflation where the kinetic and potential terms are sum-separable is ruled out by the current observations for the chaotic-type potential $V=\sum_{…
Charged Wormhole Solutions in 4D Einstein-Gauss-Bonnet Gravity
Piyachat Panyasiripan, Fereshteh Felegary, Phongpichit Channuie
In the present work, we construct models of static wormholes within the framework of 4-dimensional Einstein-Gauss-Bonnet (4D EGB) gravity an (an)isotropic energy momentum tensor (E…
Observational constraints on thawing quintessence scalar field model
Fereshteh Felegary, Kazuharu Bamba
Thawing quintessence scalar field models with the various potential forms to explain the late-time cosmic acceleration are compared to the ΛCDM model in detail by analyzing cosmolo…
