High Energy Theory Seminar: The complex Liouville string

Victor Rodriguez (UCSB)
- David Rittenhouse Laboratory, 3W2

I will introduce the complex Liouville string, a solvable critical worldsheet string theory defined by coupling two Liouville theories with complex conjugate central charges c = 13 ± is. By harnessing the non-…



Astrophysics Seminar: How micro galaxies could help constrain the properties of dark matter

Raphael Errani (Carnegie Mellon University)
- David Rittenhouse Laboratory, 4E19

Guided by the recent discovery of the faint Milky Way satellite UMa3/UnionsI, in this talk I will present the results of our controlled high-resolution simulations to discuss how ”micro galaxies” could be…

Past Seminars



Astrophysics Seminar: What can we learn from the evolution of galaxy sizes?

Kalina Nedkova (Johns Hopkins University)
- David Rittenhouse Laboratory, 4E19

Galaxies have grown significantly in size since the early Universe. While quiescent galaxies grow primarily through galaxy mergers, star-forming galaxies grow by accreting gas from their surroundings and forming new…



High Energy Theory Seminar: Gravitational atoms and black hole binaries

G.M. Tomaselli (IAS at Princeton University)
- David Rittenhouse Laboratory, 3W2

Superradiant instabilities may create clouds of ultralight bosons around rotating black holes, forming so-called "gravitational atoms". In this talk, I will review a series of papers that study the effects of a…



High Energy Theory Seminar: Candidate de Sitter Vacua

Liam McAllister (Cornell)
- David Rittenhouse Laboratory, 3W2

I will present Calabi-Yau orientifold flux compactifications of type IIB string theory that yield, at leading order in the string loop and sigma model expansions, de Sitter vacua of the form envisioned by Kachru,…



Astrophysics Seminar: Mapping Cosmic Star Formation with the CO Mapping Array Project

Patrick Breysse (NYU)
- David Rittenhouse Laboratory, 4E19

I will discuss the results of the second observing season of the CO Mapping Array Project (COMAP).  COMAP is a line intensity mapping experiment seeking to probe the cosmic star formation history by mapping the 115…



High Energy Theory Seminar: Apparent Fine Tunings for Field Theories with Broken Space-Time Symmetries

Alberto Nicolis (Columbia University)
- David Rittenhouse Laboratory, 3W2

I will exhibit a class of effective field theories that have hierarchically small Wilson coefficients for operators that are not protected by symmetries but are not finely tuned. These theories possess bounded target…
