- High Energy Seminar
- Realizing large-field inflation with stabilizer fields in string theory
- Time: 3:30 pm
- Place: 4272 Chamberlin Hall
- Speaker: Aitor Landete
- Abstract: In this talk we will show the challenge of building a stringy embedding, which in the low-energy regime, reproduces the well-known models in supergravity of chaotic inflation with stabilizer fields. We will analyze type IIA setups where the inflationary potential arises from a D6-brane wrapping an internal three-cycle, where the stabilizer field is either an open-string or bulk Kahler modulus. In the end we will analyze type IIB setups where the inflationary potential arises from a D7-brane and the stabilizer field is a complex structure modulus.

- Whitford Lecturer Ken Sembach Colloquium
- Astrophysics Flagships, Present & Future
- Time: 3:30 pm
- Place: 4421 Sterling Hall, Coffee and Cookies 3:30 pm. Talk begins at 3:45 PM
- Speaker: Dr. Ken Sembach, Director, STSci
- Abstract: NASA’s Great Observatories have revolutionized our understanding of the Universe. The James Webb Space Telescope will continue this legacy, and together with the Hubble Space Telescope and Wide-Field Infrared Telescope will usher in an era of unprecedented information about astronomical objects ranging from Solar System objects to the first stars and galaxies formed near the beginning of time. As we continue to explore, new questions arise. Are there Earth-like planets orbiting other stars, and if so are they capable of supporting life? What secrets does the ultra-faint universe hide from our view? What is the nature of dark matter and dark energy? Future flagship missions offer great promise for answering such questions. In this talk, I’ll offer some perspectives, both scientific and programmatic, on possible paths forward and the importance of truly ambitious space observatories to the future of astrophysics research.
