Abstract

The Gemini High Resolution Optical Spectrograph (GHOST) is a fiber-fed spectrograph system on the Gemini South telescope that provides simultaneous wavelength coverage from 348 to 1061 nm, and is designed for optimal performance between 363 and 950 nm. It can observe up to two objects simultaneously in a 7.′5 diameter field of regard at R ≃ 56,000 or a single object at R ≃ 75,000. The spectral resolution modes are obtained by using integral field units to image slice a 1.″2 aperture by a factor of five in width using 19 fibers in the high resolution mode and by a factor of three in width using 7 fibers in the standard resolution mode. GHOST is equipped with hardware to allow for precision radial velocity measurements, expected to approach meters per second precision. Here, we describe the basic design and operational capabilities of GHOST, and proceed to derive and quantify the key aspects of its on-sky performance that are of most relevance to its science users.

双子座高分辨率光学摄谱仪的科学性能
双子座高分辨率光学摄谱仪(GHOST)是双子座南望远镜上的一个光纤馈电摄谱仪系统,可同时覆盖 348 至 1061 nm 的波长范围,并可在 363 至 950 nm 之间获得最佳性能。它可以在 R ≃ 56,000 直径的 7.′5 视场中同时观测两个天体,或在 R ≃ 75,000 直径的视场中同时观测一个天体。光谱分辨率模式是通过使用积分场单元,在高分辨率模式下使用 19 根光纤对 1.″2 光圈进行宽度为五倍的图像切片,在标准分辨率模式下使用 7 根光纤对 1.″2 光圈进行宽度为三倍的图像切片而获得的。GHOST 配备了可进行精密径向速度测量的硬件,预计测量精度将接近每秒米。在此,我们将介绍 GHOST 的基本设计和运行能力,并进而推导和量化其天空性能中与其科学用户最为相关的关键方面。
