Jon Hakkila, P. Chris Fragile, Timothy W. Giblin
TL;DR
This paper investigates how correlations in gamma-ray burst pulse properties can serve as indicators of redshift, aiming to estimate distances for GRBs without known redshifts and improve the method's accuracy.
Contribution
It demonstrates the application of pulse correlation-based redshift estimation to GRBs lacking known redshifts and analyzes scatter to enhance reliability.
Findings
Correlations can estimate GRB redshifts.
Scatter analysis reveals potential systematic corrections.
Pulse subsets may improve estimation accuracy.
Abstract
Correlations among pulse properties in the prompt emission of long GRBs can potentially be used as cosmological distance indicators to estimate redshifts of GRBs to which these pulses belong. We demonstrate application of this technique to a sample of GRBs for which redshifts are not known. We also study the scatter of predicted redshifts of pulses found within individual bursts. We explore the characteristics of this scatter in hopes of identifying systematic corrections and/or pulse subsets that can be used to increase the technique's reliability.
