Using Gamma-ray Bursts to Study the Properties of Early Universe

Abstract

Gamma-ray bursts (GRBs) are the most luminous electromagnetic explosions in the Universe, which emit up to 1054 erg energy in the hard X-ray band. The high brightness makes them detectable out to the largest distances yet explored in the Universe. GRBs, as bright beacons in the deep Universe, would be the ideal tool to probe the properties of high-redshift universe: including the cosmic expansion and dark energy, star formation rate, the reionization epoch and the metal enrichment history of the Universe. In this talk, the speaker will discuss the recent progress on constraining dark energy and dark matter from GRBs.
