Primordial Non-Gaussianity and Extreme-Value Statistics of Galaxy Clusters
Primordial Non-Gaussianity Extreme-Value Statistics Galaxy Clusters
2011/10/20
What is the size of the most massive object one expects to find in a survey of a given volume? In this paper, we present a solution to this problem using Extreme-Value Statistics. We calculate the pro...
Measuring primordial non-Gaussianity through weak lensing peak counts
Measuring primordial non-Gaussianity weak lensing peak counts
2011/1/11
We explore the possibility of detecting primordial non-Gaussianity of the local type using weak lensing peak counts. We measure the peak abundance in sets of simulated weak lensing maps corresponding ...
Primordial non-Gaussianity in the Bispectrum of the Halo Density Field
Inflation Large Scale Structure Primordial non-Gaussianity
2010/11/11
The bispectrum vanishes for linear Gaussian elds and is thus a sensitive probe of non-
linearities and non-Gaussianities in the cosmic density eld. Hence, a detection of the bispectrum in the halo ...
