Wind from black holes may influence development of surrounding galaxies - EurekAlert
Clouds of gas in a distant galaxy are being pushed faster and faster — at more than 10,000 miles per second — out among neighboring stars by blasts of radiation from the supermassive black hole at the galaxy’s center. It’s a discovery that helps illuminate the way active black holes can continuously shape their galaxies by spurring on or snuffing out the development of new stars. A team of researchers led by University of Wisconsin–Madison astronomy professor Catherine Grier and recent graduate Robert Wheatley revealed the accelerating gas using years of data collected from a quasar, a particularly bright and turbulent kind of black hole, billions of light years away in the constellation Boötes. They presented their findings today at the 244th meeting of the American Astronomical Society in Madison.
