Cosmic string formation and the power spectrum of field configurations.
We examine the statistical properties of defects formed by the breaking of a U(1) symmetry when the Higgs field has a power spectrum P (k) ∝ kn. We find a marked dependence of the amount of infinite string on the spectral index n and empirically identify an analytic form for this quantity. We also confirm that this result is robust to changes in the definition of infinite string. It is possible...
متن کاملTrispectrum versus bispectrum in single-field inflation
In the standard slow-roll inflationary cosmology, quantum fluctuations in a single field, the inflaton, generate approximately Gaussian primordial density perturbations. At present, the bispectrum and trispectrum of the density perturbations have not been observed and the probability distribution for these perturbations is consistent with Gaussianity. However, Planck satellite data will bring a...
متن کاملCMB bispectrum, trispectrum, non-Gaussianity, and the Cramer-Rao bound
Minimum-variance estimators for the parameter fnl that quantifies local-model non-Gaussianity can be constructed from the cosmic microwave background (CMB) bispectrum (three-point function) and also from the trispectrum (four-point function). Some have suggested that a comparison between the estimates for the values of fnl from the bispectrum and trispectrum allow a consistency test for the mod...
متن کاملConstraining the WMAP9 bispectrum and trispectrum with needlets
We develop a needlet approach to estimate the amplitude of general (including non-separable) bispectra and trispectra in the cosmic microwave background, and apply this to the WMAP 9year data. We obtain estimates for the ‘orthogonal’ bispectrum mode, yielding results which are consistent with the WMAP 7-year data. We do not observe the frequency-dependence suggested by the WMAP team’s analysis ...
متن کاملCosmological parameters from lensing power spectrum and bispectrum tomography
We examine how lensing tomography with the bispectrum and power spectrum can constrain cosmological parameters and the equation of state of dark energy. Our analysis uses the full information at the twoand three-point level from angular scales of a few degrees to 5 arcminutes (50 ≤ l ≤ 3000), which will be probed by lensing surveys. We use all triangle configurations, cross-power spectra and bi...
