UWM leads new hunt to find secrets of the universe

With the recent discovery of gravitational waves, the scientific community will be turning from the quest to confirm Albert Einstein’s prediction to the future of a new branch of astronomy.

As with traditional astronomy, which includes optical, radio and X-ray observations, gravitational wave astronomy can be conducted in a variety of wavelengths to observe different cosmic phenomena.

Opening another observational “window,” UW-Milwaukee physicist Xavier Siemens is leading a consortium of 11 U.S. research institutions that formed the NANOGrav Physics Frontier Center, backed by $14.5 million from the National Science Foundation.

The center will monitor millisecond pulsars – rapidly spinning, super-dense remains of supernovas that emit beams of light on either side, like lighthouses. Scientists expect the regularly timed beams to be disrupted by gravitational waves, revealing their presence.
