Astronomers Think Powerful , Magnetic Winds Drive Growth , of Supermassive Black Holes.
'Newsweek' reports that scientists may have
unraveled the mystery of how supermassive
black holes are able to become so massive.
According to a new paper, a powerful magnetic
wind, comparable to water swirling around
a drain, is what allows these massive cosmic
phenomena to reach such immense sizes.
A supermassive black hole is typically millions to
billions of times more massive than our own sun
and is often found at the center of most galaxies. .
The paper, which was published in the journal 'Astronomy
and Astrophysics,' focused on the black hole at the
center of a galaxy about 120 million light-years from Earth.
This galaxy, known as ESO320-G030, is much more
active than our own Milky Way, with a rate of star
formation 10 times that of our own galaxy.
Using the Atacama Large Millimeter Array (ALMA) telescope,
researchers found a strong, rotating, magnetized
wind spinning around the center of the black hole.

Since this galaxy is very
luminous in the infrared,
telescopes can resolve
striking details in its center. , Susanne Aalto, study co-author and a professor

'Newsweek' reports that the team now hopes to observe the
centers of other galaxies to confirm if this process is what
enables a supermassive black hole's immense growth.
Far from all questions about this
process are answered. In our
observations we see clear evidence
of a rotating wind that helps
regulate the growth of the
galaxy's central black hole. , Mark Gorski, study co-author and an astronomer

Now that we know what to look for,
the next step is to find out how
common a phenomenon this is.
And if this is a stage which all
galaxies with supermassive
black holes go through,
what happens to them next?, Mark Gorski, study co-author and an astronomer
