GRB as luminosity indicator
arXiv:1402.4605 · doi:10.1017/S1743921313009800
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.
