CIERA Research Topics

Researchers at CIERA study a wide variety of topics, all with the aim of advancing the field of astrophysics and expanding our understanding of the Universe.

Black Hole Encounter

Black Holes & Dead Stars

Dead stars, in the form of black holes, neutron stars, or white dwarfs, and supermassive black holes at the centers of galaxies are the densest objects in the Universe. Researchers at CIERA study how they interact with each other, with stars, and with their host galaxies, as well as how they form and evolve over time.

Exoplanets & The Solar System

Since the discovery of the first exoplanet just over twenty years ago, the study of exoplanets has grown explosively. By now, astronomers have discovered thousands of exoplanets, with an incredibly diverse array of properties. This growth will undoubtedly continue into the future, as new kinds of planets are being observed with increasingly advanced telescopes. Researchers at CIERA study exoplanets theoretically and build instruments to directly image them.

Galaxies & Cosmology

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.

Gravitational Waves & Multi-Messenger Astronomy

The discovery of gravitational waves with LIGO opened a whole new window into the cosmos. Previously 'dark' phenomena such as black hole mergers, which emit no light, can now be studied using the gravitational waves they emit. Some phenomena, including neutron star mergers, send us multiple 'messengers' - photons (light), gravitational waves, or neutrinos. Using combinations of these messengers to study the cosmos, called multi-messenger astronomy, is revolutionizing our view of the universe.

Life & Death of Stars

Stars are the fundamental building blocks and probes of the Universe. They are formed in stellar nurseries enshrouded by dust and gas, and end their lives in violent explosions, creating some of the most captivating events one can witness. Faculty in CIERA study, model, and observe many stages of a star's life from birth to death, the planets formed around them, how they impact their environments, as well as the compact remnants they leave behind.
