Black hole mergers may emit double chirps, giving us clues about their shape – Ars Technica
The final black hole emits more intense gravitational waves through its curved regions.
Enlarge/ Artist’s illustration of a black hole merger. New simulations suggest that colliding black holes should emit not one, but multiple telltale “chirps,” when the collision is observed from the “equator” of the final black hole.

Physicists hunt for merging black holes and other similar cosmic events through the detection of gravitational waves, from which they can glean valuable information, such as the mass of both the precursor black holes and the final, l…
