GRB as luminosity indicator
Abstract
Gamma Ray Bursts (GRBs) are found at much higher redshifts (z > 6) than Supernova Ia (z ~ 1), and hence, they can be used to probe very primitive universe. However, radiation mechanism of GRB remains a puzzle, unlike Supernova Ia. Through comprehensive description, both empirical and physical, we shall discuss the most likely way to use the constituent pulses of a GRB to find the radiation mechanism as well as using the pulses as luminosity indicators.
