The collimation-corrected gamma-ray burst energies correlate with the peak energy of their νFν spectrum

G Ghirlanda, G Ghisellini, D Lazzati - The Astrophysical Journal, 2004‏ - iopscience.iop.org
We consider all bursts with known redshift and νF ν peak energy, E. For a good fraction of
them an estimate of the jet opening angle is available from the achromatic break of their …

Toward a more standardized candle using gamma-ray burst energetics and spectra

AS Friedman, JS Bloom - The Astrophysical Journal, 2005‏ - iopscience.iop.org
The use of gamma-ray burst (GRB) energetics for cosmography has long been advanced as
a means to probe out to high redshifts, to the epoch of deceleration. However, although …

The diversity of gamma-ray burst afterglows and the surroundings of massive stars

RA Chevalier, ZY Li, C Fransson - The Astrophysical Journal, 2004‏ - iopscience.iop.org
The finding of a Type Ic supernova connected with GRB 030329 showed a massive star
origin for this burst, supporting evidence for this association in previous bursts with light …

Lorentz-factor–isotropic-luminosity/energy correlations of gamma-ray bursts and their interpretation

J Lü, YC Zou, WH Lei, B Zhang, Q Wu… - The Astrophysical …, 2012‏ - iopscience.iop.org
The bulk Lorentz factor of the gamma-ray burst (GRB) ejecta (Γ 0) is a key parameter to
