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…

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…
