Cosmological Inflation in f(R,T) Gravity with Chern-Simons Correction
Maryam Shiravand, Saeed Fakhry, Mehrdad Farhoudi
We investigate cosmological inflation within the framework of a linear form of f (R, T ) gravity that incorporates an inflaton scalar field augmented by a Chern-Simons correction i…
Cosmological Inflation in Gravity
Maryam Shiravand, Saeed Fakhry, Javad T. Firouzjaee +1
Cosmological inflation remains a key paradigm for explaining the earliest stages of the Universe, yet the theoretical limitations of General Relativity (GR) motivate the developmen…
Dynamical friction shear and rotation in Chaplygin cosmology
A. Del Popolo, Saeed Fakhry, Maryam Shiravand +1
In this study, we build upon the findings of Del Popolo et al. (2013) by further analyzing the influence of dynamical friction on the evolution of cosmological perturbations within…
Matching JWST UV Luminosity Functions with Refined CDM Halo Models
Saeed Fakhry, Maryam Shiravand, Antonino Del Popolo
The James Webb Space Telescope (JWST) has unveiled a population of unexpectedly massive and luminous galaxies at redshifts , posing a significant challenge to the stan…
Primordial Black Hole-Neutron Star Merger Rate in Modified Gravity
Saeed Fakhry, Maryam Shiravand, Marzieh Farhang
In this work we investigate the merger rate of primordial black hole-neutron star (PBH-NS) binaries in two widely-studied modified gravity (MG) models: Hu-Sawicki gravity an…
Perturbation Spectra of Warm Inflation in Gravity
Maryam Shiravand, Mehrdad Farhoudi, Parviz Goodarzi
We investigate the warm inflationary scenario within the context of the linear version of f (Q, T ) gravity, coupled with both the inflaton scalar field and the radiation field, un…
