On the question of measuring spatial curvature in an inhomogeneous universe
Chi Tian, Stefano Anselmi, Matthew F. Carney +3
The curvature of a spacetime, either in a topological sense, or averaged over super-horizon-sized patches, is often equated with the global curvature term that appears in Friedmann…

Linear Point and Sound Horizon as Purely Geometric standard rulers
Márcio O'Dwyer, Stefano Anselmi, Glenn D. Starkman +3
The Baryon Acoustic Oscillations feature (BAO) imprinted in the clustering correlation function is known to furnish us cosmic distance determinations that are independent of the co…

Cosmic distance inference from purely geometric BAO methods: Linear Point standard ruler and Correlation Function Model Fitting
Stefano Anselmi, Pier-Stefano Corasaniti, Ariel G. Sanchez +3
Leveraging the Baryon Acoustic Oscillations (BAO) feature present in clustering 2-point statistics, we aim to measure cosmological distances independently of the underlying backgro…
