Probing Sources of GRBs with the Two-Component Model
Abstract
We present recent results on the two-component decomposition of emission of GRBs. In particular, we discuss relation of the high energy components with the GeV excesses and relation of the low energy components with the X-ray excesses found in spectra of GRBs. We also discuss statistical differences of the component properties and evolution of the ratio of the components intensities from the brightest to moderately bright GRBs. We show that these differences are incompatible with prediction of a simple cosmological transformation of standard sources. Finally we suggest a generalisation of the two-component decomposition which we call a Global Fit Analysis.
