Azimuthal geodesics in closed FLRW cosmological models
Christian G. Boehmer, Antonio d'Alfonso del Sordo, Betti Hartmann +1
We study geodesics in Friedmann-Lema{\^ı}tre-Robertson-Walker (FLRW) cosmological models and give the full set of solutions. For azimuthal geodesics, in a closed universe, we give…

Azimuthal geodesics in closed FLRW cosmologies
Christian G. Boehmer, Antonio d'Alfonso del Sordo, Betti Hartmann
Modern cosmology is closely linked to our understanding of radial null geodesics as these model the propagation of light signals through an expanding universe. Azimuthal geodesics,…
