An Imaging Spectrometer for Long-Term Studies of Emission- Line Objects

为了使用俄亥俄州立大学/洛厄尔天文台72英寸望远镜对发射线物体进行长期研究，将建造一台成像法布里·珀罗光谱仪。该仪器将使用商用标准具(昆斯盖特仪器)，分辨率为R=2500和R=30,000。它将在紫外线(UV)和红色光谱部分工作，总共需要4个标准具和2个相机/准直器。将使用紫外线泛滥的电荷耦合器件(CCD)探测器。高通量、高量子效率和相对较大的观测时间相结合，将使首席研究员能够在一个中等尺寸的望远镜上进行世界级的天文学。俄亥俄州立大学和洛厄尔天文台将提供5.7万美元的直接匹配资金，外加约10万美元的工资用于该项目。NSF的额外资金将允许建造该仪器，然后俄亥俄州立大学和洛厄尔天文学家将使用它来广泛研究活动星系、不规则星系、超新星遗迹、行星星云、HII区域和太阳系天体的发射线。

An Imaging Fabry Perot Spectrometer will be constructed in order to carry out long-term studies of emission-line objects using the Ohio State/Lowell Observatory 72-inch telescope. This instrument will use commercially available etalons (from Queensgate Instruments) with resolving powers of R=2500 and R=30,000. It will operate in both the Ultraviolet (UV) and red parts of the spectrum, requiring a total of 4 etalons and 2 camera/collimator sets. An UV flooded Charge Coupled Device (CCD) detector will be used. The combination of high throughput, high quantum efficiency, and relatively large amounts of observing time will allow the Principal Investigator to carry out world-class astronomy on a modest-sized telescope. Ohio State and Lowell Observatory are provideing $57,000 in direct matching funds plus about $100,000 in salaries for the project. The additional NSF funds will allow construction of the instrument, which will then be used by a variety of Ohio State and Lowell astronomers for extensive studies of the emission lines from active galaxies, irregular galaxies, supernova remnants, planetary nebulae, HII regions, and solar system objects.
