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…
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…
Model independent calibrations of gamma ray bursts using machine learning
Orlando Luongo, Marco Muccino
We alleviate the circularity problem, whereby gamma-ray bursts are not perfect distance indicators, by means of a new model-independent technique based on Bézier polynomials. To do…
Kinematic constraints beyond using calibrated GRB correlations
Orlando Luongo, Marco Muccino
The dynamics of the Universe are revised using high-redshift data from gamma-ray bursts to constrain cosmographic parameters by means of model-independent techniques. Considering s…
