The Collimation‐corrected Gamma‐Ray Burst Energies Correlate with the Peak Energy of Their ν FνSpectrum
Open accessAbstract
We consider all bursts with known redshift and ν F 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 afterglow light curve. This allows the derivation of the collimation-corrected energy of the bursts, E γ . The distribution of the values of E γ is more spread out than in previous findings, covering about 2 orders of magnitude. We find a surprisingly tight correlation between E γ and the source frame E peak : E (1 + z ) ∝ E . This correlation can shed light on the still uncertain radiation processes for the prompt GRB emission. More importantly, if the small scatter of this newly found correlation could be confirmed by forthcoming data, it would be possible to use it for cosmological purposes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
