Investigating the cosmic distance duality relation with gamma-ray bursts
Anna Chiara Alfano, Carlo Cafaro, Salvatore Capozziello +2
Deviations from the so-called {\it cosmic distance duality relation} may result from systematic errors in distance measurements or, more interestingly, hint at new physics. Further…

Gravitational metamaterials from optical properties of spacetime media
Orlando Luongo
Gravitational optical properties are here investigated under the hypothesis of spherically-symmetric spacetimes behaving as media. To do so, we first consider two different definit…

Cosmic distance duality after DESI 2024 data release and dark energy evolution
Anna Chiara Alfano, Orlando Luongo
The cosmic distance duality relates the angular-diameter and luminosity distances and its possible violation may puzzle the standard cosmological model. This appears particularly i…
