- Plasma Physics (Physics/ECE/NE 922) Seminar
- From SOL turbulence to planetary magnetospheres: computational plasma physics at (almost) all scales using the Gkeyll code
- Time: 12:00 pm
- Place: ZOOM Meeting
- Speaker: Dr. Ammar Hakim , Princeton Plasma Physics Laboratory
- Abstract: Gkeyll is a computational plasma physics package that aims to simulate plasmas at (almost) all scales. At present, the code contains solvers for three major equation systems: Vlasov-Maxwell equations, electromagnetic gyrokinetic equations and multi-fluid moment equations. These span the complete range of plasma physics; electromagnetic shocks, turbulence and first-principles sheath physics, requiring full kinetic treatment; turbulence in tokamak core and SOL, requiring EM gyrokinetics; and planetary magnetospheres, requiring fluid treatment with proper accounting of kinetic effects to capture reconnection and current sheet dynamics. In this talk I will present an overview of our recent results in performing the first nonlinear full-f, electromagnetic gyrokinetic continuum simulations of scrape-off-layer turbulence and the key algorithmic innovations made. I will also present results from simulations of Mercury's magnetosphere using our advanced multi-moment multifluid solver. I will conclude with an overview of our program, funded by ARAP-E, to study (amongst other things) equilibrium, stability and transport of the University of Wisconsin WHAM mirror.

- Network in Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS) Seminar
- Dark Matter: A Cosmological Perspective
- Time: 3:30 pm
- Place:
- Speaker: Katie Mack , North Carolina State University
- Abstract: While it is considered to be one of the most promising hints of new physics beyond the Standard Model, dark matter is as-yet known only through its gravitational influence on astronomical and cosmological observables. I will discuss our current best evidence for dark matter's existence as well as the constraints that astrophysical probes can place on its properties, while highlighting some tantalizing anomalies that could indicate non-gravitational dark matter interactions. Future observations, along with synergies between astrophysical and experimental searches, have the potential to illuminate dark matter's fundamental nature and its influence on the evolution of matter in the cosmos from the first stars and galaxies to today.

- Abstract: Cosmology Journal Club is back! We will be having virtual meetings this semester.
Each week, we start with a couple scheduled 15 minute talks about one's research, or an arXiv paper. The last 30 minutes will typically be open to the group for anyone to discuss an arXiv paper.
All are welcome and all fields of cosmology are appropriate.
Contact Ross Cawthon, cawthon@wisc, for more information. - Astronomy Colloquium
- Investigating the Signatures of Substellar Ingestion
- Time: 3:30 pm - 5:00 pm
- Place: Zoom meeting(see Abstract ) Coffee and tea 3:30pm, Talk 3:45pm
- Speaker: Melinda Soares-Furtado, UW Astronomy Department
- Abstract: What are the observable effects induced by substellar ingestion? Do we have any hope of unambiguously detecting such signatures? In this talk, I address these open questions, describing my efforts to unveil stellar hosts that have ingested their substellar companions within open cluster environments. Such sources will offer valuable constraints to test stellar evolutionary models. Moreover, they will provide a rare opportunity to directly measure the bulk composition of substellar companions. I will describe the challenges of modeling the substellar disassociation process, particularly as it pertains to dense brown dwarf companions. I will review promising engulfment-derived chemical and rotational tracers. Lastly, to detect these cannibal stars, I will emphasize a need for targeted photometric and spectroscopic surveys among stars in open clusters.
