Cosmic Parallax as a probe of late time anisotropic expansion
Claudia Quercellini, Paolo Cabella, Luca Amendola +2
Cosmic parallax is the change of angular separation between pair of sources at cosmological distances induced by an anisotropic expansion. An accurate astrometric experiment like G…
Cosmic Parallax: possibility of detecting anisotropic expansion of the universe by very accurate astrometry measurements
Claudia Quercellini, Miguel Quartin, Luca Amendola
Refined astrometry measurements allow us to detect large-scale deviations from isotropy through real-time observations of changes in the angular separation between sources at cosmi…
Dark Interactions and Cosmological Fine-Tuning
Miguel Quartin, Mauricio O. Calvao, Sergio E. Joras +2
Cosmological models involving an interaction between dark matter and dark energy have been proposed in order to solve the so-called coincidence problem. Different forms of coupling…
Challenges for scaling cosmologies
Luca Amendola, Miguel Quartin, Shinji Tsujikawa +1
A cosmological model that aims at solving the coincidence problem should show that dark energy and dark matter follow the same scaling solution from some time onward. At the same t…
