The gamma-ray bursts Hubble diagram in quintessential cosmological models

摘要: It has been recently empirically established that some of the directly observed pa- rameters GRBs are correlated with their important intrinsic parameters, like luminosity or total radiated energy. These correlations were derived, tested and used to standardize GRBs, i.e., derive energy from one more observables, in order construct an estimated fiducial Hubble diagram, assuming radiation propagates standard LambdaCDM cosmological model. We extend these analyses by considering general models dark energy, updated data set high redshift GRBs. show correlation parameters only weakly depend on Moreover we apply a local regression technique estimate, model independent way, distance modulus SNIa sample containing 307 (Astier et al. 2006), calibrate 2D correlations, z <1.4. The derived calibration new which call calibrated HD. also compare HDs. turns out for common they fully statistically consistent, thus indicating both them not affected any systematic bias induced different standardizing procedures. finally our methods 95 long well-known Amati relation diagram extends redshifts ~ 8. Even this case there is consistency between datasets. This means can be test HD constrain quintessential likelihood values Omega_m w(0).
