Initial power spectrum shape | Marian Douspis
; | Date: |
1 Dec 2004 | Subject: | astro-ph | Abstract: | Mainly used to set constraints on cosmological parameters, CMB anisotropies can give information on primordial universe. Unfortunately, initial conditions and late time cosmology are degenerated. I focus on the effect of the shape of the initial power spectrum of fluctuations on the cosmological parameter estimation from CMB temperature anisotropies. Strong constraints obtained using a priori knowledge of the initial spectrum disappear when the latter is let free. | Source: | arXiv, astro-ph/0412022 | Services: | Forum | Review | PDF | Favorites |
