Cosmological Spatial Curvature with the Alcock-Paczyński Effect

Author(s): Luca Amendola, Marco Marinucci, and Miguel Quartin We propose a methodology to measure the cosmological spatial curvature by employing the deviation from statistical isotropy due to the Alcock-Paczyński effect of large scale galaxy clustering. This approach has a higher degree of model independence than most other proposed methods, being independent… [Phys. Rev. Lett. 134, 101004] Published Thu Mar 13, 2025
