Research Areas

The research conducted at Steward Observatory spans the entire field of astronomy. Our faculty, postdoctoral fellows and graduate students are involved in the construction of astrophysical models, the design and fabrication of mirrors and other optics, and the direct observation of stars and galaxies through some of the world's most advanced telescopes.

The links on the right offer overviews of many of the research directions currently being investigated at Steward Observatory and the Department of Astronomy. The range of sizes considered ranges from compact neutron stars - no larger than a city -  to the largest galaxies, galaxy clusters and the Universe itself. These observations span the entire frequency spectrum, from radio emission by gas being expelled from  black holes, to exploration of the formation of planetary systems in the infrared, to extraordinary images of the evolution of galaxies in the visible, and on to intense bursts of  X-rays coming from detonations on the surface of neutron stars.

We encourage you to explore the research of our department by following links to the right.
