WMAP3后的充盈

Inflation after WMAP3

William H. Kinney

摘要:

我根据最近WMAP 3年数据的发布讨论了暴胀宇宙学的现状。对通货膨胀的基本预测都得到了数据的支持。暴胀还能做出预言,这些预言还没有被当前的数据很好地检验过,但可以被未来的实验检验过,最值得注意的是对标度不变功率谱的偏离和原始引力波的产生。目前的数据并不支持尺度不变的光谱,但这并不是决定性的。张量模式目前受到的约束很差,慢卷暴胀并不能对原始引力波的预期振幅做出明确的预测。$r \simeq 0.01$的张量/标量比在不久的将来的测量范围内。

英文摘要:

I discuss the current status of inflationary cosmology in light of the recent WMAP 3-year data release. The basic predictions of inflation are all supported by the data. Inflation also makes predictions which have not been well tested by current data but can be by future experiments, most notably a deviation from a scale-invariant power spectrum and the production of primordial gravitational waves. A scale-invariant spectrum is disfavored by current data, but not conclusively. Tensor modes are currently poorly constrained, and slow-roll inflation does not make an unambiguous prediction of the expected amplitude of primordial gravitational waves. A tensor/scalar ratio of $r \simeq 0.01$ is within reach of near-future measurements.
