- Abstract:
Zoom Meeting ID: 302 365 8376
Zoom recording available. Please contact Josh Weber for access.
For the past two summers, Physics 103 has been taught in a semi-synchronous online format utilizing pre-recorded lectures and live discussions led by Teaching Assistants. The increased flexibility afforded by this format has resulted in a substantial increase in enrollment compared to previous summers, allowing greater access to the course for students who would otherwise have not been able to participate. In this talk I will describe the process of bringing Physics 103 online, highlight the innovative use of iOLab for remote laboratory activities, and discuss future directions for further enhancing the online course experience.
Speaker bio:
Ben received his Ph.D in physics from the University of Colorado-Boulder in 2014, having previously earned a B.S. in physics and mathematics from UW-Madison in 2007. He served as Academic Coordinator & Lecturer at the University of California-Berkeley before joining the UW-Madison physics department in 2017. Since then, he has overseen the implementation of active learning techniques in large-enrollment service courses including Physics 103 and 104. - Network in Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS) Seminar
- Cosmology of Dark Energy Radiation
- Time: 2:00 pm

- Speaker: Dr. Kim Berghaus , Caltech
- Abstract: If dark energy evolves in time its dynamical component could be dominated by a bath of dark radiation. Since dark energy was subdominant in the early universe, the dark energy radiation evades the usual stringent constraints on extra relativistic species from the cosmic microwave background, allowing for up to 9% of the energy density today to be dark radiation. In this talk, I will discuss how dark energy radiation can emerge from a fundamental theory, its predictions for cosmological observables, as well as discovery potential and constraints with existing and future precision cosmological datasets including measurements of the cosmic microwave background, baryon acoustic oscillations, and supernova data. Considering extensions that allow the dark radiation to populate neutrinos, axions, and dark photons, I will discuss the direct detection prospects of a thermal background comprised of these candidates consistent with cosmological constraints on dark energy radiation. A dark photon background is the most promising prospect for direct detection, and experimental programs such as the late dark energy radiation experiment (LADERA) will probe new parameter space.
