"Submm/FIR High Resolution Spectroscopic Studies of the Life Cycle of the ISM"

Prof. Chris Walker
University of Arizona

Understanding the life cycle of the ISM remains a key question in astrophysics today. High-resolution spectroscopic observations are needed to probe the conditions of interstellar gas in different phases of the cycle. In my talk, I will discuss how we can use high resolution spectroscopy to probe the star formation phase as well as the global distribution of the cold neutral medium (CNM) and warm neutral medium (WNM). The importance of both ground and space-based observations will be discussed.
