Syracuse University Gravitational Wave Group Link

Our group is a member of the LIGO Scientific Collaboration and is actively involved with the search for gravitational waves using data from the LIGO, GEO600, and Virgo gravitational-wave detectors. We also pursue research into gravitational-wave phenomenology and source modeling, in collaboration with our colleagues in numerical relativity.

Gravitational Waves Link

Gravitational Waves are one of the most remarkable predictions of Einstein’s theory of general relativity. These waves are ripples in the curvature of spacetime which carry information about the changing gravitational fields of distant sources. Although you can generate gravitational waves just by shaking your fist, to generate gravitational waves strong enough to be detectable with current technology needs extremely dense, massive objects, such as black holes and neutron stars, and moving at very high speeds.

By measuring gravitational waves, we hope to learn about systems that cannot be observed with existing means, such as optical, radio, infrared, etc. Gravitational waves can penetrate regions these electromagnetic waves cannot, allowing us to directly observe black holes and other massive objects in the distant Universe. Since the gravitational waves we will observe are generated by very strong gravitational fields, precision measurements of these waves will also allow us to perform unprecedented tests of the general theory of relativity.

A world-wide effort to detect gravitational waves is now underway, with detectors in the United States, Germany, Italy and Japan. The U.S. Laser Interferometer Gravitational-wave Observatory (LIGO) has recently completed the remarkable task of taking one year of data coincident between its three detectors at design sensitivity. This data may contain the first gravitational waves to be seen. Upgrades to the LIGO and Virgo detectors are underway to increase their sensitivity. A new window has been opened on the universe and the detection of gravitational radiation is one of the most eagerly anticipated events of twenty-first century physics.

Through its membership of the LIGO Scientific Collaboration, the Syracuse Gravitational Wave Group is contributing to the search for gravitational waves in LIGO and Virgo data and is helping to develop techniques which will be used to improve the advanced generation of detectors.
