The group in which he works is involved in the instrumental development for the LISA PathFinder mission (ESA), a technology precursor mission for a future space - based gravitational - wave observatory, LISA, which will detect the gravitational radiation from low frequency sources like massive black hole mergers, inspiraling stellar compact objects into massive black holes, and galactic binaries.

For a fourth time, physicists have spotted gravitational waves — ripples in space itself — set off by the merger of two massive black holes.

That's why it was a surprise when physicists with the Laser Interferometer Gravitational - Wave Observatory (LIGO) announced in February 2016 that they had detected ripples in space from the violent merger of two black holes 29 and 36 times as massive as our sun.

Physicists concluded that the first detected gravitational waves, in September 2015, were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole.

All the previous gravitational - wave detections since the first in September 2015 had been the result of two merging black holes — objects much more massive than a neutron star — which have left only gravitational waves as fleeting clues of their merger.

The detection of a supermassive black hole merger would offer new insights into how massive galaxies and black holes evolve, Mingarelli says.

A black hole merger in a massive galaxy like M87 would yield detectable gravitational waves for 4 million years, for instance, while a more modest galaxy such as the Sombrero Galaxy would offer a 160 - million - year window.

However, Marc Kamionkowski, a theoretical physicist at Johns Hopkins University in Baltimore, Maryland, says the signal from the merger of more - massive black holes should be stronger and detectable from a greater distance.

But only some of the most massive astrophysical events, such mergers of black holes and neutron stars, can produce gravitational waves strong enough to be detected on earth.

The existence of black holes tens of times more massive than our Sun was confirmed recently by the observation of gravitational waves, produced by the merger of pairs of massive black holes, with the LIGO interferometer.

The thought was that when many galaxies are close together, a merger, two galaxies colliding and melding together, would create instabilities and cause gas to fall into the super massive black hole in one of the galaxies, creating a quasar.

In a new study, the scientists show their theoretical predictions last year were correct: The historic merger of two massive black holes detected Sept. 14, 2015, could easily have been formed through dynamic interactions in the star - dense core of an old globular cluster.

GRBs are jetted explosions triggered either by the collapse of a massive star or by the merger of a neutron star with another neutron star or a black hole.

Physicists working with the Laser Interferometer Gravitational - Wave Observatory have spotted a third merger of black holes, the ultraintense gravitational fields left behind when massive stars collapse.

LISA is tuned to detect lower frequencies and longer wavelengths produced by mergers between black holes millions of times more massive than the sun.
