Team & # 39; scientists from different countries, including Germany, the US and France, studied for the first time b & # 39; great detail the quasar 3C273 environment located outside Galaxy of the Milk Way, which managed to measure the mass of its black hole with unprecedented accuracy, according to the study, published in the journal Nature.

To investigate the quasar, the specialists used the "virtual" telescope & # 39; GRAVITY at the Paranal Observatory in Chile. The instrument combines four & # 39; telescopes, resulting in & # 39; equal to one 130 meters in diameter, Which allows to detect and observed astronomical objects with precision and extremely high resolution.

"The – Our observations show that – Gas clouds revolve around the central black hole"Explains Eckhard Sturm, main author of the study, from the Max Planck Institute for Extraterrestrial Physics in Germany.

Similarly, researchers published a video b & # 39; & # 39 artistic representation; black hole which can & # 39; see how the gas created while turning around to absorb all the material to find around, at the center of the galaxy, giving place to the phenomenon known as a quasar.

"The information on the movement and size region immediately around the black hole is crucial to measure its mass," says co-author Jason Dexter. Scientists tested with & # 39; experimental way this method for the first time by establishing one mass & # 39; this black hole exceeds the solar mass b & # 39; 300 million times. F & # 39; this sense, the astrofiżiċisti GRAVITY hope that will serve in the future as a special instrument to measure the mass of & # 39; other quasars.

"This is the first time we can solve and study spatially immediate circles & # 39; black hole supermassiva outside the galaxy our matrix, the Milk Way", said Reinhard Genzel, who heads the group & # 39 ; study.

Scientists emphasize that the study & # 39; black holes and calculate their masses is an essential step to understanding how galaxies evolve.
