This project will use a new millimeter-wave spectrometer, Z-Spec, recently commissioned at the Caltech Submillimeter Observatory (CSO). Z-Spec is a grating spectrometer that uses 160 bolometers spanning the complete 1 mm atmospheric window from 195-305 GHz. The scientific goals are to 1) Use multiple CO lines to measure redshifts of a sample of the luminous dusty galaxies that make up the far-IR/submillimeter background; and 2) Conduct broad-band line surveys of nearby galaxies measuring CO isotopes, density tracers, and photo-dissociation tracers in a single spectrum.Broader impacts include hands-on training of students and postdocs in millimeter-wave instrumentation and techniques, and availability of Z-Spec to the community.

该项目将使用新的毫米波光谱仪，Z-Spec，最近在Caltech亚毫升观测值（CSO）上进行了委托。 Z-Spec是一种光光谱仪，使用160个验证仪，横跨195-305 GHz的完整1 mm大气窗。 科学目标是1）使用多个CO线来测量构成Far-Ir/simbillimeter背景的发光尘埃星系样品的红移；和2）对附近星系的宽带线调查，测量CO的同位素，密度示踪剂和单个光谱中的照片分解示踪剂。Broader的影响包括对学生的动手培训和毫米波仪器仪器和技术后的培训，以及Z-Spec的可用于社区。
