About (back to top)
The Center for Relativity and Cosmology at Troy University seeks to answer fundamental questions about the universe ranging from the nature of the relativistic jets emanating from supermassive black holes at the center of galaxies to the nature of Dark Matter. The group has several ongoing projects in astrophysics, cosmology, relativity, and differential geometry, and has active collaborations with general relativists, cosmologists, and mathematical physicists.
