When black holes collide they also produce neutrinos

Ever since astronomers first detected ultra high energy neutrinos coming from random directions in space, they have not been able to figure out what generates them. But a new hypothesis suggests an unlikely source: the mergers ...

The unfolding story of a kilonova told in X-rays

Astronomers may have detected a "sonic boom" from a powerful blast known as a kilonova. This event was seen in GW170817, a merger of two neutron stars and the first object detected in both gravitational waves and electromagnetic ...

Binary black hole spin behavior revealed using novel techniques

Research done at Cornell University has uncovered from gravitation wave data the first potential signs of spin-orbit resonances in binary black holes, a step toward understanding the mechanisms of supernovas and other big ...
