- R. G. Herb Condensed Matter Seminar
- Special Seminar by Graduate Students
- Time: 10:00 am
- Place: 5310 Chamberlin Hall
- Speaker: Abigail Shearrow (UW-Madison) and Steffen Bollmann (MPISSR-Stuttgart )
- Abstract: First Talk (30min)
Abigail Shearrow:
"Noise and efficiency of a Josephson mm-wave detector"
Second Talk (30min)
Steffen Bollmann
"Topological Green's function zeros in an exactly solved model and beyond"
- Host: Alex Levchenko
- Astronomy Colloquium
- New Insights Into Novae
- Time: 3:30 pm - 4:30 pm
- Place: 4421 Sterling Hall
- Speaker: Elias Aydi, Texas Tech University
- Abstract: Novae are panchromatic transients triggered by a thermonuclear runaway on the surfaces of white dwarf stars in interacting binaries. Our understanding of how novae are powered has been altered with the Fermi gamma-ray telescope establishing novae as bright GeV gamma-ray sources and thus a new class of particle accelerators in our Galaxy. This unexpected discovery underscores the complexity of novae and their value as laboratories for studying shocks and particle acceleration. In this talk I will highlight our ongoing multi-wavelength/multi-messenger efforts aimed at understanding how shocks work in novae. These efforts can help us probe critical but poorly understood physical processes, such as common envelope interaction, super-Eddington luminosities, particle acceleration efficiency, and dust formation around explosive transients, and are essential for a better understanding of other shock-powered transients in the Universe such as supernovae, stellar mergers, and tidal disruption events.
