The researchers are lucky to have caught this unique event because not every black -
hole merger produces imbalanced gravitational waves that propel a black hole in the opposite direction.
Not exact matches
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.
It was a burbling chirp of gravitational waves
produced by the cataclysmic birth of a black
hole from the
merger of two smaller ones.
The other aspect is that space - time is incredibly stiff: that's why you need a cataclysmic event like the
merger of two black
holes to
produce a distortion that we can measure.
The gravitational waves
produced in
mergers promised a direct way to find black
hole binaries.
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 two signals that have been
produced so far came from the collision and
merger of two black
holes in some remote part of the universe.
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
merger of two black
holes, such as the one which
produced the gravitational waves discovered by the LIGO Observatory, is considered an extremely complex process that can only be simulated by the world's most powerful supercomputers.
Rodriguez and colleagues used 52 detailed computer models to demonstrate how a globular cluster acts as a dominant source of binary black
holes,
producing hundreds of black
hole mergers over a cluster's 12 - billion - year lifetime.
If the X-ray source was caused by a GRB triggered by the
merger of neutron star with a black
hole or another neutron star, then gravitational waves would also have been
produced..
These
mergers produce shock waves, which propagate through the clusters, reaccelerating particles previously accelerated by supermassive black
holes in the galactic nuclei.
LISA is tuned to detect lower frequencies and longer wavelengths
produced by
mergers between black
holes millions of times more massive than the sun.
In 2005, astronomers announced that GRB 050709 and GRB 050509B may be have created by collisions involving two neutron stars (more from Chandra X-Ray Observatory) and ESO), but that the presence of a second flare by GRB 050724 was more likely to have been
produced by a neutron star's
merger with a black
hole (ESO).
Black
holes in the centers of galaxies could accelerate
mergers between objects and
produce more ripples in space - time, also known as gravitational waves, a new study suggests.
This awesome video (
produced by SXS lensing) shows an actual simulation of the black -
hole merger GW150914.
Otherwise unknowable details of some of the universe's most violent events — from neutron star and binary black
hole mergers, to supernova explosions and even the Big Bang itself — should be revealed by the tell - tale gravitational waves they
produce.
