Colliding Black Holes May Sing Different Gravitational Songs

is abruptly cut off — the song stops because the two black holes have become one. – See more at: http://www.space.com/32723-colliding-black-holes-sing-different-songs.ht… What is the sound of two black holes

Dense stellar clusters may foster black hole megamergers

…existence of stellar binary black holes, which gave rise to the signal in the first place. Stellar binary black holes are formed when two black holes, created out of the…

Unraveling black hole spin

Scattered throughout every galaxy are black holes, regions that gobble up matter and energy. Although we can’t see black holes, scientists can infer their size, location and other properties by…

Ripple Effect: Gravitational Waves Begin to Reveal a Hidden Universe

…binary system had a mass of about 30 Suns. Until now, we’ve only known about much smaller black holes or supermassive black holes with masses of millions or billions of…

LIGO detects merging black holes for third time

signal: The spin of at least one of the black holes may have been “antialigned” with the orbital angular momentum — the direction in which the black holes were orbiting…

Scientists identify a black hole choking on stardust

…telescopes on the event to learn more about how black holes grow and evolve. The MIT-led team looked through data collected by two different telescopes and identified a curious pattern…

For second time, LIGO detects gravitational waves

…away. The colliding black holes are less massive than those that generated the first gravitational wave signal. The masses of the newly detected black holes are also more representative of…

Scientists observe supermassive black hole feeding on cold gas

…feeding its bottomless well. The observations, published today in the journal Nature, represent the first direct evidence to support the hypothesis that black holes feed on clouds of cold gas….

Scientists detect radio echoes of a black hole feeding on a star

…how black holes devour matter and regulate the growth of galaxies. Scientists from MIT and Johns Hopkins University have now detected radio signals from the event that match very closely…

An answer to why our galaxy’s black hole is a finicky eater

…consisting of a characteristic X-ray spectrum. To see which theory is most likely to explain the black hole’s inactivity, the team first looked at X-ray emissions surrounding Sagittarius A*. The…
