“Thunderous Chirp” –Signals Death Spiral Collision of Titanic Black Holes

Colliding Supermassive Black Holes

 

Astronomers have spotted a distant pair of titanic black holes each with a mass more than 800 million times that of our sun headed for a collision in a galaxy roughly 2.5 billion light-years away. The supermassive black holes (inset above) are lit up by warm gas and bright stars that surround the objects. The finding improves estimates of when astronomers will first detect gravitational waves emanating from the black hole pair “a million times louder than those detected by LIGO.”

“We tend to think about particles as being tiny but, theoretically, there is no reason they can’t be as big as a galaxy,” says Asimina Arvanitaki, The Aristarchus chair in theoretical physics at the Perimeter Institute for Theoretical Physics in Waterloo, Canada about solving the mystery of dark matter.

Neutron Stars Merging

 

Since the historic finding of gravitational waves from two black holes colliding over a billion light years away was made in 2015, physicists are advancing knowledge about the limits on the precision of the measurements that will help improve the next generation of LIGO tools and technology used by gravitational wave scientists.

“It could have been a neutron star that collapsed to a black hole after some time or turned immediately into a black hole,” said Karl Wette, at Australia National University and a member of Center of Excellence for Gravitational Wave Discovery. Scientists were not sure what was formed from the neutron-star merger that was detected in August last year. “Our new project will help to provide critical information about what we get from the merger of two neutron stars.”

On October 16, 2017, an international group of astronomers and physicists excitedly reported the first simultaneous detection of light and gravitational waves from the same source–a merger of two neutron stars. Now, a team that includes several University of Maryland astronomers has identified a direct relative of that historic event.
