Gamma-Ray Bursts, Peak Energy Correlations, Energy Indicators.

Gamma-ray bursts (GRBs) are the most powerful explosions in the universe. Over the past two decades, several GRB energy and luminosity correlations were discovered. These correlations typically involve an observable parameter, like the observed peak energy, E_p,obs, and a non-observable quantity, like the equivalent isotropic energy, E_iso. This paper provides a brief review of GRB peak energy correlations. Specifically, it focuses on the Amati relation, which correlates E_p,obs and E_iso, and the Ghirlanda relation, which correlates E_p,obs and E_y, the total energy corrected for beaming. The paper also discusses the physical interpretation of these relations in the context of the internal shock model.
