摘要:

远红外光谱探测器(FIRdac)是响应欧洲航天局(ESA)和中国科学院(CAS)发出的双边小型任务呼吁的候选任务。FIRdac是一颗在低地球轨道运行的小型卫星(~ 1米望远镜)。它由许多外差探测波段组成,目标是太赫兹(THz)和超太赫兹(>1 THz)频率范围内的关键分子和原子跃迁。FIRdac带是:[CII] 158微米(1.9THz),[NII] 205微米(1.46THz),[CI] 370微米(0.89THz),CO(6-5)433微米(0.69THz)。FIRdac的主要目标是在四条远红外线上进行无偏差的全天光谱调查,提供银河系的第一张3D地图(高光谱分辨率)。光谱测量将以赫歇尔的遗产为基础,并补充由红外天文台和AKARI天文台进行的宽带全天测量。此外,FIRdac将能够对附近和遥远的星系进行有针对性的观测,从而能够对ISM组件进行深入研究。

英文摘要:

The Far-InfraRed Spectroscopic Explorer (FIRSPEX) is a candidate mission in response to a bi-lateral Small-mission call issued by the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS). FIRSPEX is a small satellite (~1m telescope) operating from Low Earth Orbit (LEO). It consists of a number of heterodyne detection bands targeting key molecular and atomic transitions in the terahertz (THz) and Supra-Terahertz (>1 THz) frequency range. The FIRSPEX bands are: [CII] 158 microns (1.9 THz), [NII] 205 microns (1.46 THz), [CI] 370 microns (0.89 THz), CO(6-5) 433 microns (0.69 THz). The primary goal of FIRSPEX is to perform an unbiased all sky spectroscopic survey in four far-infrared lines delivering the first 3D-maps (high spectral resolution) of the Galaxy. The spectroscopic surveys will build on the heritage of Herschel and complement the broad-band all-sky surveys carried out by the IRAS and AKARI observatories. In addition FIRSPEX will enable targeted observations of nearby and distant galaxies allowing for an in-depth study of the ISM components.
