Sean McWilliams he is an sssistant professor at the University of West Virginia , has developed a mathematical method for calculating black hole properties from gravitational wave data. He wrote a report about his method and published it on arprint.
The document was accepted for publication in Physical Review Letters.
Two years have passed since the LIGO detector team made a world championship title when it was discovered that they had detected gravitational waves. Since then, workers have continued to work there and elsewhere, seeking a better understanding of black holes, the fusion of neutron stars and, ultimately, gravity itself.
However, this has been hampered in several ways: the source of gravitational waves that combine black holes is so complex that it is believed that the signals they produce cannot be interpreted mathematically. Instead, scientists interpret signals by comparing them with signals produced by computer simulations.
In this new effort, McWilliams (member of the LIGO Scientific Collaborative Council) claims to have developed mathematical formulas that can be used to calculate signals.
The calculation involves the use of the deepest stable circular orbit (ISCO), an area around the black hole about three times the distance to the event horizon where objects can roam the black hole without falling into the hole.
Look for mathematical solutions to the problem. McWilliams explained that he solved the problem simply by leaving the last state of the united black hole. Instead, he used the general theory of relativity to calculate what would happen to a small table when it was rolled into the last black hole.
This allows it to calculate signals from ISCO and inward. The analytical method uses two formulas to study gravitational waves that emerge from colliding black holes.
He argued that the results were as accurate as those provided by the simulation. He also suggested using it in future general relativity tests and LIGO data analysis, because the researchers observed more collisions with black holes. More work is needed in this field than others before McWilliams’ testimony can be confirmed.
