引力波、暗能量和暴胀

Gravitational waves, dark energy and inflation

Wei-Tou Ni

摘要:

本文首先对引力波按频率进行了完整的分类:(1)超高频带(1 THz以上);(二)甚高频带(100 kHz - 1 THz);(iii)高频带(10 Hz - 100 kHz);(iv)中频带(0.1 Hz - 10 Hz);(v)低频带(100 nHz - 0.1 Hz);(vi)甚低频带(300 pHz - 100 nHz);(vii)超低频带(10 fHz - 300 pHz);(八)哈勃(极低)频带(1 aHz - 10 fHz);(九)哈勃-哈勃频带(低于1 aHz)。在简要讨论了不同频段的探测方法后,回顾了空间引力波探测任务的概念和现状,包括LISA、ASTROD、ASTROD-GW、Super-ASTROD、DECIGO和Big Bang Observer。然后我们讨论了暗能量方程的确定,以及利用空间引力波探测器探测暴胀物理。

英文摘要:

In this paper we first present a complete classification of gravitational waves according to their frequencies: (i) Ultra high frequency band (above 1 THz); (ii) Very high frequency band (100 kHz - 1 THz); (iii) High frequency band (10 Hz - 100 kHz); (iv) Middle frequency band (0.1 Hz - 10 Hz); (v) Low frequency band (100 nHz - 0.1 Hz); (vi) Very low frequency band (300 pHz - 100 nHz); (vii) Ultra low frequency band (10 fHz - 300 pHz); (viii) Hubble (extremely low) frequency band (1 aHz - 10 fHz); (ix) Infra-Hubble frequency band (below 1 aHz). After briefly discussing the method of detection for different frequency bands, we review the concept and status of space gravitational-wave missions --- LISA, ASTROD, ASTROD-GW, Super-ASTROD, DECIGO and Big Bang Observer. We then address to the determination of dark energy equation, and probing the inflationary physics using space gravitational wave detectors.
