Comparing a Cosmos
The group compared their observations with a computer-generated indication that unnatural gas descending towards a black hole. They found that what astronomers had formerly suspicion of as a firm donut structure around wasn’t indeed plain during all — instead, they found a energetic round settlement of issuing gas that resembled a H2O fountain.
This “fountain” is combined when cold gas falls towards a black hole and forms a torus. As a gas gets closer to a black hole, it starts to feverishness adult and mangle detached into particular molecules and afterwards atoms, that turn ionized (as they remove electrons). Some of these atoms are engrossed by a black hole, though some fire out above or next a hoop in outflows. These atoms afterwards tumble behind onto a disk, formulating a three-dimensional structure that invariably circulates prohibited gas. The best human analogue is a invariably present H2O fountain, such as one that can be found in a city park.
“By questioning a suit and placement of both a cold molecular gas and comfortable atomic gas with ALMA, we demonstrated a start of a supposed ‘donut’ structure around active black holes. Based on this discovery, we need to rewrite a astronomy textbooks,” Izumi pronounced in a press release.
