Fastest and most furious ultraviolet wind聽near聽a black hole鈥痜ound by 91亚色 researchers

A team led by 91亚色 researchers has discovered the fastest wind near a supermassive black鈥痟ole鈥痚ver鈥痜ound at ultraviolet wavelengths, driven by鈥痶he disc of matter,聽or quasar, surrounding the black hole.鈥犫淭his quasar has a black hole of聽1.7鈥痓illion鈥痶imes鈥痶he mass of the Sun.聽That鈥檚聽typical.聽What鈥檚聽not typical is that it聽has gas moving towards us at 30 per cent of the speed of light,鈥 says 91亚色 Professor Patrick Hall鈥痮f the Faculty of Science.

Black hole wind is speeding up, new study finds

Clouds of gas in a distant galaxy are being pushed faster and faster out among neighbouring stars by blasts of radiation from the supermassive black hole at the galaxy鈥檚 centre, 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.

Next-gen astronomical survey makes its first observations toward understanding the cosmos

TORONTO, Nov. 2, 2020 鈥 The Sloan Digital Sky Survey鈥檚 (SDSS) fifth generation collected its very first observations of the cosmos at 1:47 a.m. on Oct. 24. As the world's first all-sky time-domain spectroscopic survey, SDSS-V will provide groundbreaking insight into the formation and evolution of galaxies 鈥 like our own Milky Way 鈥 and the supermassive black holes that lurk at their centers.
