- Chaos & Complex Systems Seminar
- Some possible regulatory changes for U.S. financial markets
- Time: 12:05 pm
- Place: 4274 Chamberlin (Refreshments will be served)
- Speaker: Don Hester, UW Department of Economics
- Abstract: This talk is awkward because regulatory change is contentious and legislation about changes is being hotly debated as I organize my comments. Consequently, I will briefly 1) explain why new regulations are needed, 2) propose some reforms that address these needs, and then 3) critically comment on likely legislation.
- Astronomy Colloquium
- Spatially-resolved studies of super star cluster feedback in Starburst Galaxies
- Time: 3:30 pm - 5:00 pm
- Place: 3425 Sterling Hall
- Speaker: Mark Westmoquette, University College - London
- Abstract: Understanding starburst-driven outflows is important for many reasons within the context of galaxy evolution. However, to understand outflows on the large scale, the details of feedback mechanisms from individual star clusters must first be understood. In this talk I will discuss recent results from a number of high spatial and spectral resolution optical integral field spectroscopic studies of the ionized gas environment surrounding super star clusters (SSCs) within nearby starbursts (e.g. NGC 1569, M82, NGC 1140). Through dynamical, excitation and density measurements, these studies are allowing us to build up a picture of (1) how power is fed from these clusters into the surrounding ISM, and (2) how the ISM properties affect how this power is directed.
