Constraints On Holographic Cosmological Models From Gamma Ray Bursts
  We use Gamma Ray Bursts (GRBs) data from Y. Wang (2008) to put additional
constraints on a set of cosmological dark energy models based on the
holographic principle. GRBs are among the most complex and energetic
astrophysical events known in the universe offering us the opportunity to
obtain information from the history of cosmic expansion up to about redshift of
$z\sim 6$. These astrophysical objects provide us a complementary observational
test to determine the nature of dark energy by complementing the information of
data from Supernovas (e.g. Union 2.1 compilation). We found that the $\Lambda
CDM$ model gives the best fit to the observational data, although our
statistical analysis ($\Delta AIC$ and $\Delta BIC$) shows that the models
studied in this work ("Hubble Radius Scale" and "Ricci Scale Q") have a
reasonable agreement with respect to the most successful, except for the "Ricci
Scale CPL" and "Future Event Horizon" models, which can be ruled out by the
present study. However, these results reflect the importance of GRBs
measurements to provide additional observational constraints to alternative
cosmological models, which are mandatory to clarify the way in which the
paradigm of dark energy or any alternative model is correct.
