Gravitational wave search provides insights into galaxy mergers

6 April 2016 Astronomy Now

New results from NANOGrav — the North American Nanohertz Observatory for Gravitational Waves — establish astrophysically significant limits in the search for low-frequency gravitational waves. This result provides insight into how often galaxies merge and how those merging galaxies evolve over time.

Race to detect gravitational waves intensifies

31 March 2015 Astronomy Now

One of the great challenges in astrophysics is the detection of low-frequency gravitational waves — elusive ripples in the fabric of space-time caused by extremely energetic and large-scale cosmic events. To this end, the National Science Foundation (NSF) has awarded the North American Nanohertz Observatory for Gravitational Waves $14.5 million over 5 years.
