| Abstract: |
I describe two instruments designed for coordinated observations of the submillimeter galaxy population. AzTEC is a 144-element bolometer camera designed to survey fields and detect submillimeter galaxies in the 1.1mm band. In June of 2005, AzTEC completed a successful engineering run at the JCMT. The instrument then returned to the JCMT in October for a series of science programs, which will result in a set of catalogs of the submillimeter galaxy population that span a wide range of environments. SPEED is a 4-pixel photometer that uses frequency selective bolometers to observe in four colors simultaneously in each pixel (for a total of 16 detectors). SPEED will be used for follow-up observations of sources found by AzTEC as well as for the measurement of the Sunyaev-Zel’dovich effect in clusters. SPEED’s band centers are 2.1mm, 1.4mm, 1.1mm, and 0.85mm. Because each color is observed through the same optics, the relative calibration of the four bands will be excellent. SPEED is under construction now with a planned deployment to the SMT in 2006. These two instruments will eventually be installed at the LMT as facility instruments. |
