Constraining Cosmological Parameters From Statistical Superluminal Effects Without a Distance Ladder
Hichem Guergouri, Omar Nemoul, Jamal Mimouni
We employ a statistical approach to study apparent superluminal motion of luminous sources in an expanding flat Friedmann--Lemaître--Robertson--Walker universe, explicitly incorpor…
Non-Radial Free Geodesics. II. In Spatially Curved FLRW Spacetime
Omar Nemoul, Hichem Guergouri, Jamal Mimouni
This paper presents an in-depth exploration of timelike free geodesics in spatially curved Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime. A unified approach for these geodes…
Non-Radial Free Geodesics. I. In Spatially Flat FLRW Spacetime
Omar Nemoul, Hichem Guergouri, Jamal Mimouni
This paper provides an analytical examination of non-radial geodesics within the context of the spatially flat Friedmann Lemaître Robertson Walker (FLRW) spacetime. Using the symme…
Studying the Behavior of Radial Free Geodesics in ΛCDM Model
Omar Nemoul, Hichem Guergouri, Jamal Mimouni
This paper presents an analytical study of the behavior of radial free-geodesics in the Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime within the Lambda Cold Dark Matter (ΛCD…
A Curvature Operator for a Regular Tetrahedron Shape in LQG
Omar Nemoul, Noureddine Mebarki
An alternative approach introducing a 3 dimensional Ricci scalar curvature quantum operator given in terms of volume and area as well as new edge length operators is proposed. An e…
