Abstract :

Timing and spectral data of two GRBs (050525 and 100621A) obtained by SWIFT BAT Mission are analyzed using cross–correlation function (CCF). We established relations between varying energy–flux, energy–lag and energy–luminosity. Different energy bands in GRBs showed lag between them. Luminosity is found to increase for the energy bands (15–25 keV to 50–100 keV) but decreased for the higher band, 100–150 keV. This may be attributed to convergence of bulk matter towards the core under its own gravity during implosion for the formation of black hole in collapsar. Both GRBs exhibited almost similar trends for the flux. The gradient of bulk matter is maximum near the high spinning of the core and as a result outer surface shows decrease in the flux for the high as well as low energy bands.
