Professor Margaret Hanson is working with Chilean Astronomers, Profs Jura Borissova and Radostin Kurtev of the University of Valparaiso, Chile and Valentin Ivanov of the European Southern Observatory in Santiago, Chile, to confirm and characterize newly identified massive clusters at infrared wavelengths. These clusters, which lie deep within the inner regions of our Milky Way Galaxy, can not be seen at traditional optical wavelengths where previous searches have been completed. The clusters have been identifed using galactic surveys at infrared wavelengths. Hanson and her collaborators then perform follow up spectroscopic observations of the individual stars within the cluster at infrared wavelengths to characterize the nature of the cluster, e.g. distance, age, mass.

Professor Hanson will be supported as a Visiting Scientist at the European Southern Observatory in Santiago, Chile in June and July 2008 as part of this collaborative effort.
