Studying Cosmology With GRB Correlations |
|
Abstract |
In order to use GRBs as cosmological tools, we have tried to standardizing them with respect to the most exploited and robust correlation, the "E_p,i- intensity" correlation. We have also tested the variations of this correlation in terms of different luminosity indicators and analyzed the variations of each of this correlation on the basis of the scatter and omega_M computations and have reached to some considerable conclusions. Also, to understand the selection effects, instrumental bias and the nature of such correlations, we have analyzed the FERMI GRB spectra resolving it in terms of short time intervals. We tried to check the reliability of the correlation from this analysis and also tried to study the correlation's behavior within individual GRB. |
