- Physics ∩ ML Seminar
- Physics meets ML to solve cosmological inference
- Time: 11:00 am - 12:15 pm
- Place: Online Seminar: Please sign up for our mailing list at www.physicsmeetsml.org for zoom link
- Speaker: Ben Wandelt, Institut d’Astrophysique de Paris / Institut Lagrange, Sorbonne University and Center for Computational Astrophysics, Flatiron Institute, New York
- Abstract: The goal of cosmological inference is to learn about the origin, composition, evolution, and fate of the cosmos from all accessible sources of astronomical data, such as the cosmic microwave background, galaxy surveys, or electromagnetic and gravitational wave transients. Traditionally, the field has progressed by designing and modeling intuitive summaries of the data, such as n-point correlations. This traditional approach has a number of risks and limitations: how do we know if we computed the most informative statistics? Did we forget any summaries that would have provided additional information or break parameter degeneracies? Did we take into account all the ways the model is affecting the data? To be feasible, the traditional approach imposes approximations on the statistical modeling (e.g. the likelihood form) and on the physical modeling. I will discuss a new mode of cosmological inference: simulation-based, full-physics modeling, made feasible through multiple advances in 1) machine-learning, 2) in the way we design and run simulations of cosmological observables, and 3) in how we compare models to data. The goal is to use current and next generation data to reconstruct the cosmological initial conditions and constrain cosmological physics much more completely than has been feasible in the past. I will discuss current status, and ways to meet the new challenges inherent in this approach, including robustness to model misspecification.

- Graduate Program Event
- Women of CTA
- Time: 11:30 am - 12:30 pm
- Place: visit for YouTube or Facebook watch links
- Speaker: Leslie Taylor, UW–Madison Physics
- Abstract: In honour of the International Day of Women and Girls in Science, which aims to raise awareness about the work and achievements of women in STEM and to promote equal opportunities in the field, the CTA Observatory (CTAO) will hold its third edition of “Women of CTA.” For the first time, the event will be carried out virtually through the CTA YouTube and Facebook channels at 18:30 on Thursday, 11 February.
“Women of CTA” will feature three female astrophysicists – Elina Lindfors (University of Turku), Mireia Nievas (Instituto de Astrofísica de Canarias) and Leslie Paige Taylor (University of Wisconsin-Madison) – who will share their work developing the physics, software and hardware for gamma-ray astronomy, as well as their professional and personal experiences in the field. The event, moderated by Alba Fernández-Barral (CTA Observatory), will include a “Question & Answer” session with the viewers.
- Cosmology Journal Club
- Time: 12:00 pm - 1:00 pm
- 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
- The Astrophysics of Gas with Simulations
- Time: 3:30 pm - 5:00 pm
- Place: Zoom meeting(see Abstract ) Coffee and tea 3:30 pm, Talk 3:45 PM
- Speaker: Simeon Bird, UC Riverside
- Abstract: The large scale distribution of gas in the Universe contains
the answers to many mysteries, such as the nature of dark matter, the sources of ionizing photons, and global trends in star formation. Cosmological simulations are the only way to understand these questions. I will talk about our ongoing simulation effort, ASTERIX. A particular focus of ASTERIX is z > 2, the era probed by upcoming NASA flagship missions JWST and WFIRST. In pursuit of this focus, we have implemented novel models for hydrogen and helium reionization, and run a 250 Mpc/hbox simulation with a resolution comparable to Illustris-TNG 100. I will discuss our models and present some preliminary results at z > 5.

- Phenomenology of Magnetic Black Holes
- Time: 2:00 pm - 3:00 pm
- Place: For zoom link, sign up at:
- Speaker: Nicholas Orlofsky, Carleton University
- Abstract: Magnetically charged black holes are interesting solutions of the Standard Model and general relativity. They may possess a “hairy” electroweak-symmetric corona outside the event horizon, which speeds up their Hawking radiation and leads them to become nearly extremal on short timescales. Their masses could range from the Planck scale up to the Earth mass. I will present various methods to search for primordially produced magnetic black holes and provide estimated upper limits on their abundance.
