The Cold Dark Matter plus Cosmological constant Module (LCDM)

Na atual versao usamos a normalizacao do WMAP (sem ondas gravitacionais) a expressao foi adaptada de Eisenstein e Hu (ApJ 511, 5, 1999) de forma a fornecer sigma_8 = 0,84. A fracao de massa dos halos e obtida de Sheth e Tormen (MNRAS 308, 119, 1999) Todos os modelos consideram Omega_Total = Omega_M + Omega_L = 1,0

"Best Fit" do WMAP-3: omega_m = 0,238, omega_b = 0,042, omega_l = 0,762, h = 0,734, sigma_8 = 0,744 Veja que sigma_8 pelo WMAP e' obtido atraves da recombinacao. Outras estimativas (p.e. aglomerados de galaxias) fornecem sigma_8 = 0,84. Conjunto de dados: WMAP-3: omega_m = 0,238, omega_b = 0,042, omega_l = 0,762 h = 0,734, sigma_8 = 0,84 WMAP-1: omega_m = 0,29, omega_b = 0,44, omega_l = 0,71 h = 0,72, sigma_8 = 0,9
