Distinguishing Between Void Models and Dark Energy with Cosmic Parallax and Redshift Drift
Miguel Quartin, Luca Amendola
Two recently proposed techniques, involving the measurement of the cosmic parallax and redshift drift, provide novel ways of directing probing (over a time-span of several years) t…

Viable Singularity-Free f(R) Gravity Without a Cosmological Constant
V Miranda, Sergio E. Joras, Ioav Waga +1
Several authors have argued that self-consistent gravity models distinct from CDM are almost ruled out. Confronting such claims, we present a particular two-parameter $f(…

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…
