Recent results from BOOMERANG-98 and MAXIMA-1, taken together with COBE DMR, provide consistent and high signal-to-noise measurements of the cosmic microwave background power spectrum at spherical harmonic multipole bands over 2<l less similar to 800. Analysis of the combined data yields 68% (95%) confidence limits on the total density, Omega(tot) approximately 1.11+/-0.07 (+0.13)(-0.12), the baryon density, Omega(b)h(2) approximately 0.032(+0.005)(-0.004) (+0.009)(-0.008), and the scalar spectral tilt, n(s) approximately 1.01(+0.09)(-0.07) (+0.17)(-0.14). These data are consistent with inflationary initial conditions for structure formation. Taken together with other cosmological observations, they imply the existence of both nonbaryonic dark matter and dark energy in the Universe.
BOOMERANG - 98和MAXIMA - 1的最新结果,与COBE DMR的数据相结合,在2<l≤800的球谐多极波段上提供了对宇宙微波背景功率谱的一致且高信噪比的测量。对合并数据的分析得出了关于总密度Ω(tot)≈1.11±0.07(+0.13)(-0.12)、重子密度Ω(b)h²≈0.032(+0.005)(-0.004)(+0.009)(-0.008)以及标量谱指数n(s)≈1.01(+0.09)(-0.07)(+0.17)(-0.14)的68%(95%)置信限。这些数据与结构形成的暴胀初始条件一致。与其他宇宙学观测结果相结合,它们意味着宇宙中存在非重子暗物质和暗能量。
