Events at Physics
Events During the Week of June 13th through June 20th, 2021
- Academic Calendar
- Graduate School Summer 2021: Summer Degree Window Period doctoral degree deadline
- Time: 11:55 pm
- Abstract: https://grad.wisc.edu/current-students/doctoral-guide/ *Important Note: The “Window Period” is the time between the end of one degree period and the beginning of the next. You must have been registered for the previous semester (Fall, Spring, or Summer). If all degree requirements are met by the end of the window period, your degree will be granted for the following semester. However, you will not have to register or pay fees for the next semester.

- Network in Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS) Seminar
- Signature of a quark-hadron phase transition from g-mode oscillations in neutron stars
- Time: 2:00 pm
- Place: Zoom https://berkeley.zoom.us/j/91922781599
- Speaker: Prashanth Jaikumar, California State University Long Beach
- Abstract: Neutron stars contain matter at extremely high density and gravitational waves from neutron stars can help us discover new forms of matter. I will present my recent work on computing the adiabatic sound speed in neutron stars and its application to g-mode oscillations as a promising signature of a mixed phase. I will also discuss estimates of g-mode damping in neutron/quark matter.
- Host: Baha Balantekin
- Physics ∩ ML Seminar
- Explaining Neural Scaling Laws
- Time: 11:00 am
- Place: Online Seminar: Please sign up for our mailing list at www.physicsmeetsml.org for zoom link
- Speaker: Ethan Dyer, Google
- Abstract: Neural networks exhibit systematic, empirically predictable, performance gains as a function of dataset and model size over many orders of magnitude. I will discuss recent work attempting to understand the origin of these neural scaling laws in deep neural networks and solvable models.
- NPAC (Nuclear/Particle/Astro/Cosmo) Forum
- Detection of 12 potential PeVatrons by LHAASO and Implications for Galactic Neutrino Emission and Diffuse sub-PeV Gamma-ray Emission
- Time: 10:00 am
- Place: https://uwmadison.zoom.us/j/92121862473?pwd=aXJkSlJQQUhIT1EwcGdkMVNNQW1yUT09
- Speaker: Ruoyu Liu, Nanjing University
- Abstract: The Large High Altitude Air Shower Observatory (LHAASO) is a multi-component instrument for TeV-PeV gamma rays and TeV-EeV cosmic rays. Very recently, LHAASO published a list of 12 sources with detection of >100 TeV gamma rays at more than 7 sigma confidence level. I will introduce this result and discuss the implications for high-energy Galactic neutrino emission and Galactic diffuse sub-PeV gamma-ray emission.

- Host: Lu Lu
- Cosmology Journal Club
- Time: 12:00 pm
- Abstract: 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.
