Growth, geometry, and early-universe split of the matter density parameter
Felicitas Keil, Isaac Tutusaus, Alain Blanchard
The paper separates the present‑day matter density parameter Ωₘ into geometric, growth, and early‑universe contributions using DES, Planck, DESI BAO, Pantheon+ supernovae, and RSD…
Probing the Distance Duality Relation with Machine Learning and Recent Data
Felicitas Keil, Savvas Nesseris, Isaac Tutusaus +1
The distance duality relation (DDR) relates two independent ways of measuring cosmological distances, namely the angular diameter distance and the luminosity distance. These can be…
Phase Diffusion of Light Immersed In Quantum Tides: Open Quantum System Approach
Fateme Shojaei Arani, Brahim Lamine, Alain Blanchard +1
The interaction between quantum gravitational waves (GWs) and electromagnetic (EM) fields is investigated within the open quantum system formalism, where GWs are considered as a he…
Revisiting van Citter-Zernike correlations in the presence of primordial gravitational waves
Fateme Shojaei Arani, Malek Bagheri Harouni, Brahim Lamine +1
In this paper, we develop a quantum field theory framework to describe the interaction between a gravitational wave (GW) background and an electromagnetic (EM) field emitted from a…
Cosmological measurement of the gravitational constant using the CMB, the BAO and the BBN
Brahim Lamine, Yacob Ozdalkiran, Louis Mirouze +5
Recent cosmological observations have provided numerous new observations with increasing precision that have led to the era of precision cosmology. The exquisite quality of these o…
