FIRI --远红外干涉仪

FIRI - a Far-Infrared Interferometer

Frank Helmich, Rob Ivison

摘要:

恒星和吸积物体发出的能量有一半是在FIR波段到达我们这里的,还没有得到适当的探索。我们提出了一个强大的远红外干涉仪的任务,FIRI,进行高分辨率成像光谱在FIR。这种关键的观测能力对于揭示气体和尘埃如何演变成恒星和行星,宇宙中第一个发光物体如何点燃,星系如何形成以及超大质量黑洞何时生长至关重要。FIRI将解开恒星形成和吸积到黑洞上的宇宙历史,并将追踪像我们银河系这样的静止星系的组装和演化。也许最重要的是,FIRI将观察行星系统形成的所有阶段,并通过其对行星系统中尘埃结构的成像能力,识别可能存在生命的类地行星。因此,它将直接解决我们理解宇宙如何发展和演变的根本问题-欧空局的宇宙愿景提出的问题。

英文摘要:

Half of the energy ever emitted by stars and accreting objects comes to us in the FIR waveband and has yet to be properly explored. We propose a powerful Far-InfraRed Interferometer mission, FIRI, to carry out high-resolution imaging spectroscopy in the FIR. This key observational capability is essential to reveal how gas and dust evolve into stars and planets, how the first luminous objects in the Universe ignited, how galaxies formed, and when super-massive black holes grew. FIRI will disentangle the cosmic histories of star formation and accretion onto black holes and will trace the assembly and evolution of quiescent galaxies like our Milky Way. Perhaps most importantly, FIRI will observe all stages of planetary system formation and recognise Earth-like planets that may harbour life, via its ability to image the dust structures in planetary systems. It will thus address directly questions fundamental to our understanding of how the Universe has developed and evolved - the very questions posed by ESA's Cosmic Vision.
