Research Interests: Molecular Cloud Properties

___________________________________________________________________________________________________________________________________________________

 One of my primary interests is the study of the physical properties of molecular clouds within the Milky Way. The molecular gas can be readily probed using millimeter and submillimeter wavelength spectroscopy. These data provide information on the mass, density, temperature, spatial structure, and dynamics of the gas within these clouds. Much of my observational work is done using either the Five College Radio Astronomy Observatory 14-m telescope located near Campus or the Submillimeter Wave Astronomy Satellite (1998 - 2005). One of the last large projects completed with the FCRAO 14-m telescope was a map of 100 square degree region of the Taurus Molecular Cloud Complex in the emissions of the J=1-0 transitions of 12CO and 13CO. In addition to providing the distribution of molecular gas in this region, the high resolution spectra provide information on the cloud kinematics. The image below shows the 12CO emission that is color coded, with red representing gas moving away, blue gas moving toward, and green gas moving at the average velocity of the cloud.
