Theory Seminar (High Energy/Cosmology)
Swampland conjectures and their phenomenological application
Time: 2:00 pm
Place: 5280 Chamberlin Hall
Speaker: Pablo Soler, Heidelberg University
Abstract: An enormous amount of four dimensional effective field theories, many of them with interesting phenomenological implications, can be obtained from compactifications of string theory. The set of these theories is known as the landscape of string theory. It has been suggested that, beyond this landscape, there exist consistent-looking effective field theories that cannot be embedded into UV complete theories of quantum gravity, in particular into string theory. They are said to belong to the swampland. In this talk I will describe some of the conjectures that define the boundaries of the swampland and implications they have on phenomenology, in particular in models of dark matter and inflation. When applied to axions, the swampland program naturally leads to the study of gravitational instantons and Euclidean wormholes. I will also review some of the properties and puzzles posed by these exotic objects.

Annual Outreach Open House
2nd Annual Physics Outreach Open House
Time: 2:00 pm
Place: 2241 Chamberlin
Abstract: The Physics Department outreach program is the oldest in the country. We have immediate need for people to get involved in all aspects, from maintaining websites to making presentations to K-12 students. Wisconsin is a great place to do physics outreach: with a little practice you can inspire a room full of kids to jump up and down while saying “we love physics!”.

Astronomy Colloquium
Introducing FLAG: the phased array feed for the Green Bank Telescope
Time: 3:30 pm
Place: 4421 Sterling Hall, Coffee and cookies 3:30 PM. Talk Begins at 3:45 PM
Speaker: DJ Pisano, West Virginia University
Abstract: The Focal L-band Array on the GBT (FLAG) is a phased array receiver for the GBT with an equivalent sensitivity to the existing single feed receiver. It will speed up HI surveys by a factor of 5-7x and pulsar/transient surveys by a factor of a few. I will present the results from our commissioning observations and let you know how you can propose to use it in the future.
