A team of researchers has managed to collect interesting information about collisions between black holes. When two black holes collide, the resulting black hole will release intense gravitational waves that can offer information about its shape.
Black holes have been a source and interest for the scientific community for a long while, thanks to their interesting traits. In the case of a clash between black holes, a high-intensity pulse will be released for a few seconds. This pulse can be observed by scientists to learn more about them.
Despite the tremendous forces involved in the collision, the phenomenon will not release light. Astronomers rely on the gravitational waves generated at the same time to trace the changes which take place, including the behavior of the black hole.
During the study, the researchers created advanced simulations of black hole collisions with the help of supercomputers. The simulations were analyzed with the aim to trace and monitor the rapid transformations of gravitational waves that are released by the remnant black hole. The signals are more complex and varied than it was previously thought.
The gravitational waves, also known as chirps, tend to become more intense as the moment of the clash arrives. With the help of the gravitational waves, research can determine the speed and size of the orbits followed by the black holes. A constant chirp will be released by the remnant black hole after the clash takes place.
When the collision is observed from a specific position, the signal is more complex, and several chirps can be observed before it vanishes. This trait is tied to the shape of the resulting black hole, and the signal is more powerful when it’s released from the curbed areas.
The study is the first one to provide data about the relationships between gravitational waves and the resulting black hole.
