Molecular Gas and the Nuclear Starburst in NGC 253

Thursday October 1, 2015
2:00 pm


 Presenter:  Mark Gorski, UNM/NRAO
 Series:  Center for Astrophysics Research and Technologies Seminar Series
 Abstract:  I will present an analysis of NGC 253 from the Survey of Water and Ammonia in Nearby Galaxies (SWAN). NGC 253 is a starburst galaxy residing 3.5Mpc away. The starburst is nucleated, concentrated in the centermost 600pc. We have identified seven regions of molecular gas in the galaxy center associated with the nuclear starburst. I will discuss three molecular species, ammonia(NH3), water(H2O), and methanol(CH3OH), and what they tell us about the galactic ecosystem in NGC 253. I am able to derive kinetic temperatures of the molecular gas which suggests a single warm 140K component. In addition there are several maser sites associated with star forming regions and expanding shells.
