Abstract:
We present a comparative study of the observed properties of the
optical and X-ray afterglows of short- and long-duration γ-ray
bursts (GRBs). Using a large sample of 37 short and 421 long GRBs, we
find a strong correlation between the afterglow brightness measured
after 11hr and the observed fluence of the prompt emission. Both the
optical (R band) and X-ray flux densities (FR and FX) scale with
the γ-ray fluence, Fγ. For bursts with a known redshift,
a tight correlation exists between the afterglow flux densities at
11hr (rest frame) and the total isotropic γ-ray energy,
Eγ,ISO: FR,X∝Eγ,ISOα, with
α∼1.
Description:
In this study, we include GRBs detected by all satellites, beginning
with GRB 970111, the first localization with follow-up observations
capable of detecting an afterglow, and ending over a decade later,
with GRB 071227.
