Pluto image gallery!
Here are images from simulations that Scott Kenyon and I produced from our research. These snapshots show views from a New Horizons-like flyby, if the spacecraft were launched billions of years ago, when the satellites, Styx, Nix, Kerberos and Hydra were forming around Pluto and its partner/moon Charon. The pictures show Pluto and Charon surrounded by a few small satellites embedded in a ring of many tiny debris particles.
Welcome to my webpage, hosted by the Department of Physics & Astronomy at the University of Utah. I am a Professor, working in theoretical and computational astrophysics, in areas of planetary and galactic dynamics, as well as some relativistic astrophysics. Here you will find information about my research, recent courses, and other things that I do at The U.

◊ Planet formation
Scott Kenyon and I have developed a code to simulate the formation of planets. This longterm project has enabled us to understand how rocky (Earth), gaseous (Jupiter) and icy (Pluto) planets grow. Check out this MPEG animation of a planet moving through a disk of smaller planetesimals. The movie illustrates how planets can migrate toward their host star, a phenomenon that may affect the formation of planets like Earth--and not necessarily in a good way!
◊ Hypervelocity stars
Warren Brown, Margaret Geller, Scott Kenyon, and I study the origin of hypervelocity stars, which travel through the Galaxy at speeds up to 800 km/s. They likely started out as members of binary stars in the center of the Galaxy, and got flung out when they strayed too close to the Galaxy's supermassive black hole. Their binary partners got trapped by the black hole and may eventually get consumed by it.
◊ Relativistic astrophysics
Hot, glowing gas flowing near a black hole can serve as a diagnostic of the physics of strongly curved spacetime. I have worked to predict the radiation from this gas in radio waves and X-rays.
