2nd Workshop on Gamma-Ray Bursts in the Afterglow Era


6. GRBs and cosmology

I. G. Mitrofanov
The collective estimation of red shift of GRBs

I. Mittrofanov introduced method for estimate "fluency" over 
cosmological invariant parameter (CIP):
         CIP = Ep * t_h
where
         Ep  ... spectral peak energy
         t_h ... part of the emision time
