Friedmann-Lemaître-Robertson-Walker cosmology through the lens of gravitoelectromagnetism
Valerio Faraoni, Geneviève Vachon, Robert Vanderwee +1
Friedmann-Lemaître-Robertson-Walker cosmology is examined from the point of view of gravitoelectromagnetism, in the approximation of spacetime regions small in comparison with the…
Revisiting geodesic observers in cosmology
Geneviève Vachon, Robert Vanderwee, Valerio Faraoni
Geodesic observers in cosmology are revisited. The coordinates based on freely falling observers introduced by Gautreau in de Sitter and Einstein-de Sitter spaces (and, previously,…
Quasi-geodesics in relativistic gravity
Valerio Faraoni, Geneviève Vachon
A four-force parallel to the trajectory of a massive particle can always be eliminated by going to an affine parametrization, but the affine parameter is different from the proper…
On the Kuzmin model in fractional Newtonian gravity
Andrea Giusti, Roberto Garrappa, Geneviève Vachon
Fractional Newtonian gravity, based on the fractional generalization of Poisson's equation for Newtonian gravity, is a novel approach to Galactic dynamics aimed at providing an alt…
When Painlevé-Gullstrand coordinates fail
Valerio Faraoni, Geneviève Vachon
Painlevé-Gullstrand coordinates, a very useful tool in spherical horizon thermodynamics, fail in anti-de Sitter space and in the inner region of Reissner-Nordström. We predict this…
