This visualization presents 22 X-ray binary systems that host confirmed black holes, all shown at the same scale and with their orbits sped up by about 22,000 times. The view of each system reflects how we see it from Earth.
A binary black hole (BBH) is a system consisting of two black holes in close orbit around each other. Like black holes themselves, binary black holes are often divided into stellar binary black holes, formed either as remnants of high-mass binary star systems or by dynamic processes and mutual capture; and binary … See more Supermassive black-hole (SMBH) binaries are believed to form during galaxy mergers. Some likely candidates for binary black holes are galaxies with double cores still far apart. An example active double nucleus is See more The first observation of stellar-mass binary black holes merging, GW150914, was performed by the LIGO detector. As observed from Earth, a pair of black holes with estimated masses around 36 and 29 times that of the Sun spun into each other and merged to form … See more One of the problems to solve is the shape or topology of the event horizon during a black-hole merger.
