We have recently commissioned a novel infrared ($0.9-1.7$ $μ$m) integral field spectrograph (IFS) called the Wide Integral Field Infrared Spectrograph (WIFIS). WIFIS is a unique instrument that offers a very large field-of-view (50$^{\prime\prime}$ x 20$^{\prime\prime}$) on the 2.3-meter Bok telescope at Kitt Peak, USA for seeing-limited observations at moderate spectral resolving power. The measured spatial sampling scale is $\sim1\times1^{\prime\prime}$ and its spectral resolving power is $R\sim2,500$ and $3,000$ in the $zJ$ ($0.9-1.35$ $μ$m) and $H_{short}$ ($1.5-1.7$ $μ$m) modes, respectively. WIFIS's corresponding etendue is larger than existing near-infrared (NIR) IFSes, which are mostly designed to work with adaptive optics systems and therefore have very narrow fields. For this reason, this instrument is specifically suited for studying very extended objects in the near-infrared such as supernovae remnants, galactic star forming regions, and nearby galaxies, which are not easily accessible by other NIR IFSes. This enables scientific programs that were not originally possible, such as detailed surveys of a large number of nearby galaxies or a full accounting of nucleosynthetic yields of Milky Way supernova remnants. WIFIS is also designed to be easily adaptable to be used with larger telescopes. In this paper, we report on the overall performance characteristics of the instrument, which were measured during our commissioning runs in the second half of 2017. We present measurements of spectral resolving power, image quality, instrumental background, and overall efficiency and sensitivity of WIFIS and compare them with our design expectations. Finally, we present a few example observations that demonstrate WIFIS's full capability to carry out infrared imaging spectroscopy of extended objects, which is enabled by our custom data reduction pipeline.
On-sky commissioning of MAROON-X: A new precision radial velocity spectrograph for Gemini North
MAROON-X是一个光纤馈电的,红色光学的,高精度径向速度摄谱仪,最近在夏威夷莫纳克亚山的双子北望远镜上投入使用。它的分辨能力为85,000,波长覆盖范围为500-920 nm,可提供晚K和M矮星的径向速度测量,精度低于50 cm s $^{-1}$。MAROON-X是目前北半球唯一一台8米级望远镜上的光学EPRV摄谱仪,也是唯一一台大型望远镜上的EPRV仪器,可供整个美国社区使用。我们在这里报告2019年12月的调试活动结果和早期科学结果。

Spectroscopic Survey of Eclipsing Binaries with a Low Cost Échelle Spectrograph -- Scientific Commissioning
我们目前的科学成果,最近委托埃歇尔摄谱仪上的0.5米的Solaris-1望远镜在南非天文台。BACHES是一种低成本的狭缝式埃歇尔摄谱仪,在5,500埃的分辨率为21,000。所描述的设置是完全远程操作和部分自动化的。定制的硬件组件已被设计为允许光谱和光度观测。设置通过专用软件控制。该系统的吞吐量使我们能够获得光谱与平均SNR为22,在6375毫米的30分钟曝光的$V=10$马格目标。仪器的稳定性主要受环境温度变化的影响。我们获得了一个明亮的(V = 5.9等)光谱双星的径向速度RMS值,与$V = 10.2$等食双星的0.59 km s $^{-1}$和1.34 km s $^{-1}$一样好。径向速度测量已经与可用的光度光变曲线相结合。我们提出了六个食双星系统的模型,并为以前已知的目标,我们比较我们的结果与文献中提供的。已确定的二元组分的质量与3%的误差为一些目标。我们面对我们的结果与基准值的基础上测量的HARPS和UCLES光谱仪4米级望远镜,并找到非常好的协议。所描述的设置是非常有效的,并且非常适合于光谱勘测。我们现在可以光谱表征约300食双星每年高达10.2等,假设典型的天气条件下,在SAAO没有一个单一的观察之旅。
