Large-angle non-Gaussianity in simulated high-resolution CMB maps
  A detection or nondetection of primordial non-Gaussianity by using the cosmic
microwave background radiation (CMB) offers a way of discriminating
inflationary scenarios and testing alternative models of the early universe.
This has motivated the considerable effort that has recently gone into the
study of theoretical features of primordial non-Gaussianity and its detection
in CMB data. Among such attempts to detect non-Gaussianity, there is a
procedure that is based upon two indicators constructed from the skewness and
kurtosis of large-angle patches of CMB maps, which have been proposed and used
to study deviation from Gaussianity in the WMAP data. Simulated CMB maps
equipped with realistic primordial non-Gaussianity are essential tools to test
the viability of non-Gaussian indicators in practice, and also to understand
the effect of systematics, foregrounds and other contaminants. In this work we
extend and complement the results of our previous works by performing an
analysis of non-Gaussianity of the high-angular resolution simulated CMB
temperature maps endowed with non-Gaussianity of the local type, for which the
level of non-Gaussianity is characterized by the dimensionless parameter
$f_{\rm NL}^{\rm local}$
