Cosmological Spatial Curvature with the Alcock-Paczynski Effect
Luca Amendola, Marco Marinucci, Miguel Quartin
We propose a methodology to measure the cosmological spatial curvature by employing the deviation from statistical isotropy due to the Alcock-PaczyÅski effect of large scale galax…

A model-independent tripartite test of cosmic distance relations
Isabela Matos, Miguel Quartin, Luca Amendola +2
Cosmological distances are fundamental observables in cosmology. The luminosity (), angular diameter () and gravitational wave () distances are all trivially…
