Towards a new model-independent calibration of Gamma-Ray Bursts

Understand

Current data on baryon acoustic oscillations and Supernovae of Type Ia cover up to $z\sim 2.5$.

• These observations play a very important role in the determination of cosmological parameters and have been widely used to constrain the $\Lambda$CDM and models beyond it.
• To extend the investigation to higher $z$, Gamma-Ray Bursts (GRBs) stand out as one of the most promising observables since can probe the universe up to $z\sim9.4$.
• The use of GRB correlations is still a challenge due to the spread in their intrinsic properties.
