Testing And Improving The Luminosity Relations For Gamma-Ray Bursts, Andrew Collazzi
Testing And Improving The Luminosity Relations For Gamma-Ray Bursts, Andrew Collazzi
LSU Doctoral Dissertations
Gamma Ray Bursts (GRBs) have several luminosity relations where a measurable property of a burst light curve or spectrum is correlated with the burst luminosity. These luminosity relations are calibrated for the fraction of bursts with spectroscopic redshifts and hence the known luminosities. GRBs have thus become known as a type of "standard candle"; where standard candle is meant in the usual sense that their luminosities can be derived from measurable properties of the bursts. GRBs can therefore be used for the same cosmology applications as Type Ia supernovae, including the construction of the Hubble Diagram and measuring massive star …
