Astronomers are closing in on a radically new kind of cosmic map--a map that shows the universe in gravitational waves.

The process is hard. This new, preliminary version is uncertain. But we're seeing a fresh view of reality come into focus.

This map, which measures the directional power of the gravitational wave signal, reveals some intriguing results. Astrophysicists generally expect the gravitational wave signal to be approximately the same in all directions. This arises from key cosmological assumptions that the Universe is homogeneous and isotropic, generally evenly distributed in all directions and evenly mixed. Surprisingly our map shows a โ€˜hot spotโ€™ - an area of stronger gravitational wave signal in the Southern Hemisphere. This hot spot could suggest that a nearby, extraordinarily massive black hole binary is drowning out others, but it may also just be a statistical anomaly.
