论文摘要
热通胀是原始通货膨胀后短暂的低能通胀，在超对称宇宙学的背景下解决了模量问题。在热通货膨胀方案中，原始功率谱在大尺度上适度红移，但在热通货膨胀开始时的尺度小于地平线的尺度上被抑制了1/50倍。我们通过研究CMB光谱畸变，晕圈丰度和21厘米氢管线来比较热通货膨胀模型与温暖的暗物质和$λ$ CDM场景。
Thermal inflation, a brief low energy inflation after the primordial inflation, resolves the moduli problem in the context of supersymmetric cosmology. In the thermal inflation scenario, the primordial power spectrum is modestly redshifted on large scales, but suppressed by a factor of 1/50 on scales smaller than the horizon size at the beginning of thermal inflation. We compare the thermal inflation model with the warm dark matter and $Λ$CDM scenarios by studying CMB spectral distortions, halo abundances, and 21cm hydrogen lines.
