AI 中文摘要
我们正在开发SuperFIRE概念，它基于麦哲伦望远镜上FIRE光谱仪的传统，是一台宽带（约340纳米至2.5微米）、中等分辨率（R = 10,000）的单次拍摄自然视场光谱仪，用于盖亚大望远镜（GMT），由卡弗里基金会支持。该单目标光谱仪被设想为一种初光仪器，可在自然视场下运行，并随着望远镜和自适应光学系统的成熟而具备长期能力。本文讨论了自该概念十年前在爱丁堡SPIE首次提出以来，其科学案例和设计是如何演变的。设计变更的主要驱动因素是对微弱瞬变和多信使事件的快速跟踪，以及在红外波段对詹姆斯·韦伯太空望远镜（JWST）观测的补充。通过利用快速低噪声探测器和现代制造技术，我们预计能实现高吞吐量和低散射，在几分钟的积分时间内达到天空极限性能，实现快速响应和深度积分。由于其通用的标准配置，SuperFIRE将作为一种实用的即拍即得跟踪光谱仪运行，所需的观测或规划开销最小，且对大气条件不敏感。
英文摘要
We are developing the SuperFIRE concept, which builds on the heritage of the FIRE spectrograph at Magellan, as a broadband (about 340 nm to 2.5 um) intermediate resolution (R=10,000) single-shot natural seeing spectrograph for the Giant Magellan Telescope (GMT) with support from the Kavli Foundation. This single-object spectrograph is envisioned as a first-light instrument that can operate in natural seeing and grow in long-term capability as the telescope and adaptive optics systems mature. Here we discuss how the science cases and design have evolved since the concept was initially conceived and presented at SPIE in Edinburgh ten years ago. The primary drivers for the design changes are fast follow-up of faint transients and multi-messenger events, and complementarity to JWST observations in the infrared. By leveraging fast low-noise detectors and modern fabrication techniques we expect high throughput and low scatter that delivers sky limited performance in a few minutes of integration time for fast response and deep integrations. SuperFIRE will operate as a practical point-and-shoot follow-up spectrograph thanks to a versatile standard configuration that needs minimal observing or planning overheads and is insensitive to atmospheric conditions.
