Events at Physics
Events on Thursday, February 11th, 2021
- Graduate Program Event
- Women of CTA
- Time: 11:30 am
- 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
- 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
- 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.
