What happens when two supermassive black holes collide? In this video, ESA scientists Paul McNamara and Matteo Guainazzi explain how we could combine the observing power of two future ESA missions, LISA and Athena, to study these cosmic clashes and their mysterious aftermath for the first time.
LISA, the Laser Interferometer Space Antenna, will be the first space-borne observatory of gravitational waves – fluctuations in the fabric of spacetime produced by the acceleration of cosmic objects with very strong gravity fields, like pairs of merging black holes. Athena, the Advanced Telescope for High-ENergy Astrophysics, will be the largest X-ray observatory ever built, investigating some of the hottest and most energetic phenomena in the cosmos with unprecedented accuracy and depth. Currently in the study phase, both missions are scheduled for launch in the early 2030s.
