16 Oct 2000 | | Journal: | Astrophys.J. 555 (2001) 125 | | Subject: | astro-ph | | Affiliation: | Inter-University Centre for Astronomy and Astrophysics, Harish-Chandra Research Institute | | Abstract: | We analyse the BOOMERANG and MAXIMA results in the context of models with $Omega_{
m Total} = 1$ and $n_s = 1$. We attempt to constrain three other parameters---$h$, $Omega_B$, and $Omega_m$---from these observations. We show that: (a) the value of $Omega_B h^2$ is too high to be compatible with primordial nucleosynthesis observations at 95% confidence level (b) universe with age greater than $ 12
m Gyr$ is ruled out at 95% confidence level and (c) the value of $Omega_m h$ is too high to be compatible with the shape of the power spectrum of gravitational clustering. In effect, our analysis shows that models with $Omega_{
m Total} = 1$ and $n_s = 1$ are ruled out by BOOMERANG and MAXIMA observations. | | Source: | arXiv, astro-ph/0010309 | | Services: | Forum | Review | PDF | Favorites | |
