Research Interest: 

Department chair Jean Turner is an extragalactic astrophysicist. She received her A.B. and Ph.D. degrees at Harvard University and UC Berkeley. Before joining UCLA as professor she worked at the Harvard-Smithsonian Center for Astrophysics, and has been a Visiting Scientist at Caltech, Space Telescope, and the Joint ALMA Observatory. She has contributed to the development and commissioning of two millimeter and submillimeter telescopes. She is a fellow of the American Association for the Advancement of Science.

Research targets include the very youngest star-forming regions. Like the youngest Galactic star-forming regions, these are typically still "embedded" in their natal dusty gas clouds. While this allows us to study their pristine natal environments, before the stars have had a chance to disperse the gas, it also means that they are hidden from optical view. To see them, one observes in the infrared, millimeter/submillimeter and radio portions of the spectrum.

In many cases the star clusters themselves are completely hidden within dusty cocoons of gas, invisible even in the near and mid-infrared. They are indirectly detectable at longer wavelengths, through the HII regions that are excited by these young clusters and their surrounding gas clouds. The nearby molecular clouds from which they formed can be detected in millimeter and submillimeter-wave emission from lines of molecules such as CO.
