Chaos & Complex Systems Seminar
Numerical modeling: Error, stability, and chaos
Time: 12:05 pm - 1:00 pm
Place: 4274 Chamberlin Hall (refreshments will be served)
Speaker: George Hrabovsky, Madison Area Science and Technology
Abstract: We rely heavily on approximation methods in science, as it is often the case that exact methods of solution are impossible with known mathematics. In this talk I will discuss the issues of approximation error, the stability of approximate solution methods, and the role of chaos in numerical modeling.

Theory Seminar (High Energy/Cosmology)
(Fundamental) Composite Models at the TeV scale
Time: 3:30 pm
Place: 5280 Chamberlin
Speaker: Andrea Tesi, University of Chicago
Abstract: New confining gauge theories offer a rich and robust phenomenology, mostly dictated by their accidental symmetries. For example, they naturally contain accidentally stable ‘baryon’ and/or ‘pion’ Dark Matter candidates. Moreover, if the strong sector enjoys chiral and custodial symmetries, it can offer a framework for Composite Higgs models, where the Higgs doublet is a partially-composite light ’pion’. I will discuss how this can be made consistent with the flavor sector of the SM and comment on the main LHC phenomenology both in direct and indirect searches.

Astronomy Colloquium
Low Mass Galaxies and their Gas at the Peak Epoch of Star Formation
Time: 3:30 pm - 5:00 pm
Place: 4421 Sterling Hall, Coffee and Cookies at 3:30 PM , Talk at 3:45 PM
Speaker: Dawn Erb, UW Milwaukee
Abstract: Because faint, low mass galaxies are numerous at high redshifts, their impact on the Universe is expected to be significant. They may host a substantial fraction of the Universe's star formation, provide many of the energetic photons needed to reionize the intergalactic medium, and affect their surroundings via powerful, starburst-driven galactic outflows. Because of their faintness, however, the properties of these galaxies are difficult to determine. I will discuss a variety of observations aimed at characterizing the physical conditions in low mass galaxies during the peak epoch of star formation, when the Universe was ~20% of its current age, with particular emphasis on the study of galactic outflows in faint galaxies.
