AI 中文摘要
我们建议为NASA ASTRA框架内考虑的任何潜在未来聚焦光学X射线任务添加仪器。该仪器是研究活动星系核(AGN)风外流与反馈、寻找失踪重子、研究星系际介质、分析整个银河系尘埃颗粒丰度与化学键的必要设备。我们得出结论,这些科学目标可通过软X射线波段(约10-40埃)中大于3000的光谱分辨率,以及比现有仪器大几倍的有效面积来实现。我们描述了一种软X射线光栅光谱仪的可能任务实施方案,该仪器可折叠进出或永久安装在光束中,能满足各种宿主任务的属性要求。小型紫外成像仪和紫外光谱仪可通过独立光学元件安装在同一平台上。这些新增仪器以1亿至2亿美元的适度成本,以及任何主要任务都能轻松容纳的重量和功耗需求,极大增强了宿主任务的科学能力。
英文摘要
We propose to add instruments to any potential future X-ray mission with focussing optics that is considered in NASA's ASTRA framework. Such an instrument is a necessity to study AGN wind outflows and feedback, find the missing baryons, study the intergalactic medium, and analyze abundances and chemical bonds in dust grains throughout the Milky Way. We conclude that those science goals can be achieved with a spectral resolving power > 3000 in the soft X-ray band (about 10-40 Ang) and an effective area a few times larger than current instruments. We describe a possible mission implementation for a soft X-ray grating spectrometer that can be folded in and out or be mounted permanently in the beam. Such an instrument can reach the requirements for a wide variety of host mission properties. A small UV imager and a UV spectrograph can be mounted on the same platform with independent optics. These added instruments vastly enhance the science capabilities of the host mission for a modest cost (100-200 million $) and with weight and power needs that can be easily accommodated in any major mission.
