PLANCK Cosmological Model Testing
The PLANCK primary science goals include testing cosmological
models. This involves checking the quality of the fit of the model to the
observations and searching for extra handles, e.g. statistics, bispectrum,
higher order moments, in order to test the models.
Quality of Model in Representing Observations
-
A Software for assessing goodness of fit - e.g. absolute likelihood and
chi-squared
-
Also need a representation for science community and public understanding
of quality of fit
-
power spectrum?
-
selected sections of map?
-
New ideas?
Cosmological Model Testing
-
Fit to standard model with n ~ 15 parameters
-
Comparison to previous results and internally
-
Comparison and consistency with all previous data
-
combined fitting to Planck and other data
-
-
Search for Non-Gaussian Fluctations
-
statistical tests
-
higher order moments
-
correlation n-point and peaks
-
Tests of Unusual Models
-
small universes
-
symmetric universes
-
-
Unknown and non-standard models
-
everyone has a pet favored model including some not yet invented
-
