Title: "Colliding Cosmologies: Cultural Conflicts and the Future of Astronomy on Mauna Kea" (Video)
[more]In a cataclysmic binary, a more-or-less normal star orbits a white dwarf so closely that matter spills from the normal star onto the white dwarf. A rich variety of behaviors results -- nova explosions, dwarf nova outbursts, accretion disk precession, magnetic channeling of the accretion flows, and much more. The light grasp and instrumentation at MDM Observatory are well-suited to studies of these objects.
[more]Stellar Population research is conducted to study the early formation history of our Milky Way galaxy and nearby satellite galaxies. Computational stellar models are compared to observations from the Hubble Space Telescope and other optical/infrared telescopes to determine the ages of stars. FACULTY CONTACT: Brian Chaboyer
[more]We are part of a team that has discovered a population of extreme starburst galaxies with star formation densities millions of times higher than in our Milky Way. These galaxies are associated with winds being launched at thousands of km/s into the intergalactic medium, and appear to represent the most extreme possible conditions for star formation in the Universe.
[more]One idea for the formation of supermassive black holes is that they grew from lower-mass "seeds" that formed in the first generation of galaxies in the early Universe. In this scenario, some such seed black holes should remain today and provide a "fossil" record of the early cosmic formation of black holes.
