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.

这是Maunakea Spectroscopic Explorer 2018图书。它旨在为国际天文学和工程界以及相关机构提供MSE科学和技术设计的所有方面的简明参考指南。当前版本是MSE科学目标及其实际实施的状态报告,继2018年1月举行的系统概念设计审查之后。MSE是一个计划中的10米级、宽视场、光学和近红外设施,旨在实现变革性科学,同时填补新兴的国际大型天文设施网络中的一个关键空白。MSE完全致力于数千至数百万天体样本的多目标光谱学。由于其独特的设计能力,它将在这一领域引领世界:它将拥有大口径(11.25米)和宽(1.52平方米)。度)视野;它将有能力以从R2500到R40,000的宽范围的光谱分辨率进行观测,具有大规模的多路复用(每次曝光4332个光谱,所有光谱分辨率在任何时候都可用),并且对目标观测效率超过80%。MSE将揭示微弱宇宙的组成和动力学,旨在精确研究微弱的天体物理现象。它还将为多波长成像调查提供关键的后续行动,例如大型综合巡天望远镜,盖亚,欧几里得,宽视场红外巡天望远镜,平方公里阵列和下一代甚大阵列。
On possible proxies of AGN light curves cadence selection in future time domain surveys
受即将到来的光度和光谱调查的启发(Vera C. Rubin Observatory Legacy Survey of Space and Time(LSST),Manuakea Spectroscopic Explorer),设计了统计代理函数来测量活动星系核(AGN)的变化-可观测量(时滞、周期性和结构函数(SF))的韵律效应。我们构建了一个多元回归模型,统计识别的节奏形式的错误模式,知道AGN的时间滞后和周期性从不同的调查。我们定义了简单的度量SF的属性,占“观察到的”SF的偏差相对于那些从均匀采样的光变曲线。我们测试了不同的观测策略的回归模型:8个AGN的长光变曲线的光学数据集的特点和人工数据集的基础上几个理想化的LSST的节奏。在合成数据集上评估SFs度量。回归模型(对于两种数据类型)预测时滞和振荡检测的节奏相似,而对于具有低可变性的光变曲线($\sim 10\%$),振荡检测的节奏不同。对于较高变异性($\sim20\%$),预测的节奏大于$F_{var}\sim 10\%$。预测的节奏是减少红移。具有密集和同质节奏的SF更有可能表现出类似的行为。具有振荡信号的SF对节奏敏感,可能影响LSST样操作策略。建议的代理人可以帮助选择光谱和光度测量的节奏策略,他们将在更大的对象样本进行进一步测试。
