My research aims
to understand the formation and
evolution of stars and galaxies, and
to place them in the context of
cosmology and the large scale
structure of the universe.
Towards this goal, I am involved in the design and construction of cutting edge millimeter-wave and radio instrumentation and the creation of data analysis for that instrumentation.
Z-Spec is a moderate resolution grating spectrometer for detecting molecular lines in local ULIRGs and carbon monoxide (CO) in high redshift galaxies. It covers the entire 200 - 300 GHz (1.6 - 1.0 mm) atmospheric window with ~1000 km/s resolution. Z-Spec was fully commissioned during the spring of 2007 and observed routinely at the Caltech Submillimeter Observatory on the summit of Mauna Kea until May of 2010. Beginning in October 2010, Z-Spec operated at the APEX telescope in Chile as a guest instrument, and will return to the CSO in early 2012.
Z-Spec has made a number of important discoveries, including a massive quantity of water surrounding a distant quasar and the determination of distance for gravitationally lensed dusty starburst galaxies.
