Welcome to CCRG

The Center for Computational Relativity and Gravitation (CCRG) is a Research Center of the College of Science (COS) and a Research Center of Excellence at Rochester Institute of Technology (RIT) dedicated to research at the frontiers of numerical relativity and relativistic astrophysics, gravitational-wave physics, its connection to experiments and observations, and high-performance computation and scientific visualization.

RIT researchers contributed to the first detection of gravitational waves, announced on Feb. 11. This milestone in physics and astronomy confirmed a major prediction of Albert Einstein’s 1915 general theory of relativity, and marked the beginning of the new field of gravitational-wave astronomy.
GW170104

Numerical Simulations of GW170104

Comparing the GW170104 signal seen by LIGO (in blue and orange) with computer simulations of black hole mergers (in black). The black circles represent the simulated black holes, scaled in proportion to their masses. Black holes can also spin about an axis, and where a simulated black hole was spinning we show the direction of the north pole with a gray arrow. The longer the arrow, the faster the spin. Interestingly, all of the simulations produce results broadly similar to the detected signal, despite their different configurations.
