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.

Kavli Fulldome Lecture Series: The Cosmos in a Heartbeat
The length of a human life barely registers on the scale of cosmic time. In spite of our relatively tiny size and our limited time here on Earth, a single generation of humans can take giant leaps forward in our understanding of the Universe. Join us to find out how dramatically our story of the

Northwestern Physics and Astronomy student Alex Gurvich presents a talk as part of the Northwestern Ready Set Go (RSG) program. The goals of the program are to increase awareness for the urgent need for excellent research communicators and to coach graduate and post doctoral researchers to improve their own presentation skills. The program focuses on three important

Isolated Disc Galaxy
Simulation of an isolated disc galaxy, looking at the disc of the galaxy face on (top panels) and edge on (bottom panels). The left-hand panels show images of the stellar light, and is what we would see if we viewed this galaxy with a telescope such as Hubble. The right-hand panels show the gas in

Density and Temperature Snapshots
Density (top) and temperature (bottom) snapshots from an idealized hydro-simulation of the circum-galactic medium of a Milky-Way-like galaxy. Note the outskirts (>70 kpc) are cool and free-falling, while the inner region is hot and pressure-supported.

Radiative-hydrodynamic Simulation of a Dusty Cloud Irradiated by a Quasar
The figure shows a radiative-hydrodynamic simulation of a dusty cloud irradiated by a quasar (located at r = 0). Radiation pressure is set to be the dominant pressure source. Left panel shows the initial conditions, while the right panel shows the cloud 10^4 years after exposure to the quasar radiation. A quasi-static density gradient develops at
