The most obvious large structures in the Universe are the galaxies, which over the span of cosmic time have been the nexus for both the evolution of stars and large-scale structure in the Universe. CIERA researchers are engaged in understanding both the evolution of the galaxies and the environments they are embedded in, as well as the stellar populations they are comprised of and the supermassive black holes they host.
Research at CIERA
CIERA researchers work on understanding the origins of structure in the Universe. Professor Faucher-Giguère’s group develops sophisticated cosmological hydrodynamic simulations of galaxy formation. The simulations are used to answer a wide variety of science questions, including how star formation is regulated in galaxies, how galaxies interact with the circum-galactic medium and the intergalactic medium, and how galaxies and their black holes co-evolve.

Shane Larson at TEDxGVSU, “Feeling Small in a Big Cosmos”
The Universe is vast beyond anything humans can easily comprehend, and it is easy to become overwhelmed by the immensity, disheartened by how insignificant we seem. But in the vastness there is a glimmer of truth that we should hold onto and use to guide us: in all the vastness we are, so far as

CIERA’s 11th Annual Public Lecture, “Cartography of the Cosmos: Mapping the Unseen”
This lecture was presented by award-winning author and Yale professor Dr. Priyamvada Natarajan at Cahn Auditorium on October 24, 2019. Natarajan discussed how mapping over time encodes radical new scientific ideas. She walked through the history of the acceptance of new astronomical ideas, and talked about the status of several current transformative (and deeply contested)
