Non-trivial boundary conditions in general-relativistic models
Davide Astesiano, Matteo Luca Ruggiero, Federico Re
We propose an alternative interpretation of dark matter effects within the framework of General Relativity. In particular, we suggest that, in astrophysical and cosmological contex…
Dark Coriolis Fields
Gabriele Bianchi, Federico Re, Oliver Fabio Piattella
We argue that the standard post-Newtonian expansion scheme used in General Relativity leaves room for time-space components of the metric to be of the same order of the us…
Quasilocal Newtonian limit of general relativity and galactic dynamics
Marco Galoppo, Federico Re, David L. Wiltshire
We present a new self-consistent perturbative expansion for realistic isolated differentially rotating systems -- disc galaxies. At leading order it is formally equivalent to Ehler…
Non zero Coriolis field in Ehlers' Frame Theory
Federico Re, Oliver F. Piattella
Ehlers' Frame Theory is a class of geometric theories parameterized by and identical to the General Theory of Relativity for . The limit does not r…
Dynamical friction in the quasi-linear formulation of modified Newtonian dynamics (QuMOND)
Pierfrancesco Di Cintio, Federico Re, Caterina Chiari
Aims. We explore the dynamical friction on a test mass in gravitational systems in the Quasi linear formulation of Modified Newtonian Dynamics (QuMOND). Methods. Exploiting the qua…
