Investigating the imprint of quintessence in cosmic magnification
Enas Mohamed, Didam Duniya, Hassan Abdalla +1
We study cosmic magnification beyond lensing in a late-time universe dominated by quintessence and cold dark matter. The cosmic magnification angular power spectrum, especially goi…
Deep Neural Networks for Estimation of Gamma-Ray Burst Redshifts
Tamador Aldowma, Soebur Razzaque
While the available set of Gamma-ray Burst (GRB) data with known redshift is currently limited, a much larger set of GRB data without redshift is available from different instrumen…
Scalar field dark energy: Insights into cosmological evolution and black hole accretion
M. Koussour, Y. Sekhmani, Alnadhief H. A. Alfedeel +2
We propose a novel approach to parameterize the equation of state for Scalar Field Dark Energy (SFDE) and use it to derive analytical solutions for various cosmological parameters.…
Modeling cosmic acceleration with a generalized varying deceleration parameter
M. Koussour, N. Myrzakulov, Alnadhief H. A. Alfedeel +2
Understanding the accelerating expansion of the Universe remains a fundamental challenge in modern cosmology. In this paper, we investigate a cosmological model parametrized by a g…
Lorentz Invariance Violation Effects on Gamma-Gamma Absorption and Compton Scattering
Hassan Abdalla, Markus Boettcher
In this paper, we consider the impact of Lorentz Invariance Violation (LIV) on the opacity of the Universe to VHE-gamma rays, compared to the effect of local under-densities…
Modified Newtonian Dynamics (MOND) as a Modification of Newtonian Inertia
Mohammed Alzain
We present a modified inertia formulation of Modified Newtonian dynamics (MOND) without retaining Galilean invariance. Assuming that the existence of a universal upper bound, predi…
