This may help solve such mysteries as how gas clouds are triggered to form new stars and when the massive
black hole at the center of every mature galaxy forms.
Scientists suspect some sources: the Big Bang itself, shock waves from supernovas collapsing into black holes, and matter accelerated as it is sucked into
massive black holes at the centers of galaxies.
All sizable galaxies are thought to be born
with black holes at their centers, and each time galaxies collide and merge the expanded galaxy should collect a new one.
These rapidly spinning neutron stars flash regular radio pulses, and in an upcoming issue of The Astrophysical Journal astronomers say that the timing of such pulses could provide a new understanding of the 4 million solar
mass black hole at the center of the Milky Way.
(In fact,
monster black holes at the centers of galaxies can cause matter around them to radiate so much light that they become some of the brightest objects in the universe.)
The relatively
quiet black hole at the center of our Milky Way galaxy could one day reignite, spewing forth so much radiation that the sky would never darken.
The most plausible explanation for this propulsive energy is that the monster object was given a kick by gravitational waves unleashed by the merger of two
hefty black holes at the center of the host galaxy.

Return Black holes at the center of sixactive galaxies are caught in the act of reeling in huge swirls ofinterstellar dust and gas in combined visible and near - infrared images taken by the Hubble Space Telescope.
A 2008 study presented evidence for an intermediate -
mass black hole at the center of Omega Centauri, based on observations made by the Hubble Space Telescope and Gemini Observatory on Cerro Pachon in Chile.
The nearby giant galaxy M87 has a
monster black hole at its center (more than 6 billion suns» worth) offering astronomers a similar «eclipse effect,» notes Doeleman.
Years of observations have revealed that Sagittarius A is likely the
super-massive black hole at the center of our galaxy, and now these telescopes are working together to get the very first picture of it.
Powerful radiation from supermassive
black holes at the center of most large galaxies creates winds that can blow gas out of the galaxies, halting star formation.
According to a new study, there are tens of thousands of
black holes at the center of the Milky Way galaxy.
Eventually, in 10 - 100 quintillion years, these stellar remnants will either have escaped their galaxy's pull, or will have spiraled into the supermassive
black hole at the center.
Note, I actually didn't crunch the numbers, so I could be wrong that our local cluster has stronger gravitational impact than the supermassive
black hole at the center of the galaxy.
«Finding evidence for a large number of
black holes at the center of the Milky Way confirms a fundamental and major prediction of galactic dynamics,» Hailey says.
But if you have clusters of
black holes at the centers of galaxies, there are mechanisms by which some could rapidly grow, form binaries and merge with each other.»
Meanwhile a project called the Event Horizon Telescope aims to use radio observatories scattered around Earth to image the supermassive
black hole at the center of the Milky Way.
Last year, astronomers turned to the supermassive
black hole at the center of our galaxy to watch it tear apart a dusty gas cloud called G2.
Until now, scientists have largely believed that such hypervelocity stars originate when binary stars get torn apart by the supermassive
black hole at the center of the Milky Way, which consumes one star and flings the other away at incredible speeds.
An artist's rendering shows the possible behavior of gas cloud G2 approaching
the black hole at the center of the Milky Way.
For the last few years, he has studied a gaggle of extremely fast - moving stars, stellar runaways that were long ago flung out of the Milky Way by the massive
black hole at its center.
Powerful radio jets from the supermassive
black hole at the center of the galaxy are creating giant radio bubbles (blue) in the ionized gas surrounding the galaxy.
Today, astronomers know that virtually every galaxy harbors a giant
black hole at its center, shaping the formation of millions of stars and even neighboring galaxies with its immense gravitational influence.
«There's no way to replicate that in an experiment unless you were to put
a black hole at the center,» says Lathrop.
Even a gargantuan artificial core with
a black hole at its center — cool as that sounds — would still be only a simulation.
«You'd have to stare at one galaxy for roughly 10,000 to 100,000 years to see a star getting disrupted by
the black hole at the center,» Pasham says.
And a neutron star nestling up next to a black hole is a plausible setup: There's one orbiting the supermassive
black hole at the center of the Milky Way.
