Abstract:
It has previously been discovered that there is a universal power-law
behavior exhibited by the late X-ray emission (LXRE) of a "golden
sample" of six long energetic GRBs, when observed in the rest frame of
the source. This remarkable feature, independent of the different
isotropic energy (Eiso) of each GRB, has been used to estimate the
cosmological redshift of some long GRBs. This analysis is extended
here to a new class of 161 long GRBs, all with Eiso>1052erg.
These GRBs are indicated as binary-driven hypernovae (BdHNe) in view
of their progenitors: a tight binary system composed of a
carbon-oxygen core (COcore) and a neutron star undergoing an induced
gravitational collapse (IGC) to a black hole triggered by the COcore
explosion as a supernova (SN).
Description:
We have built a new sample of binary-driven hypernovae (BdHNe), which
we name "enlarged sample" (ES). We collected 161 sources, which
satisfy our criteria, covering 11 years of Swift/XRT observations, up
to the end of 2015.
