AI 中文摘要
SuperSpec-MUSCAT合作组（SuMAC）致力于在大型毫米波望远镜（LMT）的MUSCAT仪器中运行SuperSpec光谱仪。SuperSpec是一种使用动力学电感探测器（KIDs）的片上滤波器组光谱仪，在1毫米大气窗口（190-300 GHz）中观测时具有中等光谱分辨率R~200。MUSCAT名义上是一台工作在1.1毫米的连续谱相机，但其设计也作为前沿探测技术的测试平台。2025年7月，三台SuperSpec装置被安装并调试在MUSCAT的低温恒温器中，仅对系统进行了最小改动。本文概述了SuperSpec在MUSCAT中的部署情况与性能，以及2025年夏季观测活动的主要结果，亮点包括对NGC253星系中CO发射线的探测、猎户座KL区域的成像，以及初步的线强度映射扫描。
英文摘要
The SuperSpec-MUSCAT Collaboration (SuMAC) is an effort to operate SuperSpec spectrometers in the MUSCAT instrument at the Large Millimeter Telescope (LMT). SuperSpec is an on-chip filterbank spectrometer using kinetic inductance detectors (KIDs), with moderate $R\sim 200$ spectral resolution for observing in the 1 mm atmospheric window (190-300 GHz). While nominally a continuum camera operating a 1.1 mm, MUSCAT was also designed to operate as a testbed for pioneering detection technologies. In July 2025, three SuperSpec devices were installed and commissioned in the MUSCAT cryostat with minimal modifications to the system. This work presents an overview of SuperSpec's deployment and performance in MUSCAT along with the main results from the Summer 2025 observation campaign. Highlights include the detection of CO emission line in the galaxy NGC253, mapping the Orion KL region, and preliminary line intensity mapping scans.
