The gravitational constant and the cosmic microwave background

Brahim Lamine, Sébastien Beauchamp, Alain Blanchard +3

The CMB constrains the gravitational constant at recombination to a few percent of its laboratory value, but the effect of on recombination itself is usually absorbed into…

Growth, geometry, and early-universe split of the matter density parameter

Felicitas Keil, Isaac Tutusaus, Alain Blanchard

While the cold dark matter (CDM) model can successfully reproduce the measurements of many cosmological probes, some discrepancies have recently emerged. It is therefore nec…

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…

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…

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…

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…
