Study shows first evidence of winds outside black holes throughout their mealtimes

New research shows the first evidence of strong winds around black holes throughout bright outburst events when a black hole rapidly consumes mass.

The study, published in Nature, sheds new light on how mass transfers to and how black holes can affect the environment around them. The research was conducted by an international team of researchers, led by scientists in the University of Alberta's Department of Physics.

Using data from three international space agencies spanning 20 years, the scientists used new statistical techniques to study outbursts from stellar-mass black hole X-ray binary systems. Their results show evidence of consistent and strong winds surrounding black holes throughout outbursts. Until now, strong winds had only been seen in limited parts of these events.

"Winds must blow away a large fraction of the matter a black hole could eat,'' described Bailey Tetarenko, PhD student and lead author on the study. "In one of our models, the winds removed 80 per cent of the black hole's potential meal."

Depending on their size, stellar-mass black holes have the capacity to consume everything within a 3 to 150 kilometre radius. "Not even light can escape from this close to a black hole," explained Gregory Sivakoff, associate professor of physics and co-author. Other, much larger black holes, called supermassive black holes, appear to have affected the formation of entire galaxies. "But even supermassive black holes are smaller than our solar system. While they are small, black holes can have surprisingly large effects," explained Sivakoff.

So, what exactly causes these winds in space? For now, it remains a mystery. "We think magnetic fields play a key role. But we'll need to do a great deal of future investigation to understand these winds," explained Craig Heinke, associate professor of physics and co-author.

"Strong disk winds traced throughout outbursts in black-hole X-ray binaries" will be published online January 22 in Nature.

There is zero evidence that black holes have power over photons, photons are a balanced magnetic particles construction thats an anti gravity particle, the magnetic lines of force, are what photons travel on around in your galaxy lensing because that the least path of resistance as we know that particle electron constructions take naturally in a magnetic environment

to any law-abiding astronomer who has any hopes to publish. To argue that the black hole emits new matter is simply heresy! Banishment is the least punishment to be expected.

Scalar waves, i.e. particles of dark matter, which interact preferably with charged particles. Similar "winds" are responsible for high temperature of interstellar gas in galactic bulges and solar corona.

To the plasma ignoramuses, just about everything that involves real plasma physics as observed in the laboratory, is a mystery.

Ah yes, job security through willful ignorance.

I said real plasma physics, not the fanciful pontifications of the infinium mathematicians.

Oh, where they exclaim their reliance on pseudoscience in the first line of the webpage?

"Magnetic reconnection (henceforth called "reconnection") refers to the breaking and reconnecting of oppositely directed magnetic field lines in a plasma."
There they are, reifying those field lines into taking the action of breaking and reconnecting... LOL!

1) Err, what are these plasma geniuses explanations for black holes? Links, please. I happen to know one, and he thinks that they are.....black holes!

2) Want me to quote you some Falthammar re MRx? However, he's a pseudoscientist in your cult, isn't he?

Here is a real plasma genius, unlike those who believe in pseudoscientific claptrap such as frozen-in fields and breaking field lines.

Why don't you quote that paper where he says the concept of moving field lines is an erroneous belief.
