Astronomy & Astrophysics
- Galaxies, Cosmology, and black holes
Professors Mike Brotherton , Adam Myers , and Danny Dale. Professor Myers' mainly studies quasars and other Active Galactic Nuclei which are powered by ultra-massive black holes at the hearts of distant galaxies. Quasars are visible across 95% of the known Universe, and visible back in cosmic history to a time when the first galaxies were forming. Quasars trace the physics of the Universe at huge distances, large timescales and extremes in mass and energy. Danny Dale uses space based observatories to study the spectral energy distributions and star formation rates of galaxies from the nearby universe to the distant universe. Mike Brotherton studies active galactic nuclei using telescopes from the radio to X-ray to understand the physics of the supermassive black holes at their centers.
- Stars and Star formation
Prof. Chip Kobulnicky uses wide-field infrared surveys such as from theSpitzer Space Telescope to understand the locations and conditions of star formation in the Milky Way, especially in regions of high obscuration that harbor massive young star clusters. His group also uses the Wyoming Infrared Observatory 2.3 m telescope (WIRO) to make long-term spectroscopic surveys of massive stars, shedding new light on their formation, evolution, and role in producing nature's most energetic events like supernova and gamma-ray bursts.
- Formation of Planetary Systems
Prof. Hannah-Jang Condell uses supercomputers to simulate the structures in protoplanetary disks around young stars where young planets are forming.
- Astronomical Instrumentation
Prof. Mike Pierce designs and builds new state-of-the art astronomical instrumentation for the WIRO telescope and other facilities.
