- Chaos & Complex Systems Seminar
- The power to change lives: The UW Odyssey Project
- Time: 12:05 pm
- Place: 4274 Chamberlin (refreshments will be served)
- Speaker: Emily Auerbach, UW Department of English
- Abstract: Yasmin’s son rescued her from a crack house in Chicago and brought her to Madison, where she enrolled in the UW Odyssey Project. She now has her bachelor’s degree, works as a substance abuse counselor, and is on her way to a master’s in social work from the UW-Madison. How can one intervention, one alteration in a pathway, change whole families and break a cycle of generational poverty? Why is improvisation the best teaching method for helping at-risk adults and youth find their voices and change their lives? Come learn how the UW Odyssey Project (www.odyssey.wisc.edu) has been transforming lives for over a dozen years.
- Host: Sprott
- Theory Seminar (High Energy/Cosmology)
- Cosmological Probes of Nearly Decoupled Dark Sectors
- Time: 3:30 pm
- Place: 5280 Chamberlin Hall
- Speaker: Josh Berger, University of Wisconsin-Madison
- Abstract: Many models of cold dark matter generate the observed relic abundance by employing dark photons and/or dark Higgs bosons as mediators. In this work, we place constraints on the mediator parameter space by considering nucleosynthesis and CMB spectral distortion constraints. We focus on the limit when the mediators have very weak mixing with the Standard Model. Before their decay, mediator abundance is frozen-in. We find dramatic improvement on the spectral distortion constraints can be generated from a proposed experiment such as PIXIE.
