Hints of Isocurvature Perturbations in the Cosmic Microwave Background?
Reijo Keskitalo, Hannu Kurki-Suonio, Vesa Muhonen +1
The improved data on the cosmic microwave background (CMB) anisotropy allow a better determination of the adiabaticity of the primordial perturbation. Interestingly, we find that r…
Correlated Primordial Perturbations in Light of CMB and LSS Data
Hannu Kurki-Suonio, Vesa Muhonen, Jussi Valiviita
We use cosmic microwave background (CMB) and large-scale structure data to constrain cosmological models where the primordial perturbations have both an adiabatic and a cold dark m…
Correlated adiabatic and isocurvature CMB fluctuations in the wake of the WMAP
Jussi Valiviita, Vesa Muhonen
In general correlated models, in addition to the usual adiabatic component with a spectral index n_ad1 there is another adiabatic component with a spectral index n_ad2 generated by…
