Contribution

It introduces a method to calibrate the Amati relation using cosmography and assesses GRBs as estimators for cosmological parameters.

Findings

Good preliminary estimate of cosmological density parameters using GRB data

Calibration of the Amati relation via cosmographic analysis

Potential of GRBs as cosmological tools

Abstract

In this work we present some applications about the use of the so-called Cosmography with GRBs. In particular, we try to calibrate the Amati relation by using the luminosity distance obtained from the cosmographic analysis. Thus, we analyze the possibility of use GRBs as possible estimators for the cosmological parameters, obtaining as preliminary results a good estimate of the cosmological density parameters, just by using a GRB data sample.
