Cosmological Model-independent Gamma-ray Bursts Calibration and its Cosmological Constraint to Dark Energy

Understand

As so far, the redshift of Gamma-ray bursts (GRBs) can extend to $z\sim 8$ which makes it as a complementary probe of dark energy to supernova Ia (SN Ia).

• However, the calibration of GRBs is still a big challenge when they are used to constrain cosmological models.
• Though, the absolute magnitude of GRBs is still unknown, the slopes of GRBs correlations can be used as a useful constraint to dark energy in a completely cosmological model independent way.
• In this paper, we follow Wang's model-independent distance measurement method and calculate their values by using 109 GRBs events via the so-called Amati relation.
