I work primarily with Dr. Jean Turner
and Dr. Sara Beck
doing radio/millimeter and IR spectroscopy of the nuclei of nearby
starburst galaxies. The radio millimeter spectroscopy is done using
the BIMA and OVRO Millimeter Interferometers
[now combined to form CARMA], the
Caltech Submillimeter
Observatory and the VLA. The
IR spectroscopy is done using the
Spitzer Space Telescope and the
W. H. Keck II Observatories. By
studying the rotational transitions of various molecules including
Carbon Monoxide (and its isotopes), Hydrogen Cyanide, Methanol,
Ammonia, and Isocyanic Acid, we hope to understand the physical
conditions such as temperature, density, morphology and kinematics, as
well as the chemical properties of molecular gas in the center of
these types of galaxies. The goal is to relate these properties to
the locations and strengths of the starburst in order to understand
what impact the conditions of the natal molecular gas have on the
occurance of these large bursts of star formation.

radio astronomy website on molecular spectroscopy.]
