Polyspectra searches for sharp oscillatory features in cosmic microwave sky data
J. R. Fergusson, H. F. Gruetjen, E. P. S. Shellard +1
We undertake a thorough search for signatures of sharp oscillatory features in the WMAP9 power spectrum and bispectrum as well as in the Planck power spectrum. For the first time,…
Combining power spectrum and bispectrum measurements to detect oscillatory features
J. R. Fergusson, H. F. Gruetjen, E. P. S. Shellard +1
The simplest inflationary models present us with few observable parameters to discriminate between them. A detection of features in the spectra of primordial density perturbations…
Towards efficient and optimal analysis of CMB anisotropies on a masked sky
H. F. Gruetjen, E. P. S. Shellard
Strong foreground contamination in high resolution CMB data requires masking which introduces statistical anisotropies and renders a full maximum likelihood analysis numerically in…
