Light-years-long filaments perpendicular to those previously discovered are sprouting from the supermassive black hole Sagittarius A*.
. But no black hole in the Milky Way generates as much cosmic hoopla as Sag A*, as the new, stubbier filaments neatly showcase.Medeiros et al. 2023
“It was a surprise to suddenly find a new population of structures that seem to be pointing in the direction of the black hole,” Yusef-Zadeh said. “We found that these filaments are not random but appear to be tied to the outflow of our black hole. By studying them, we could learn more about the black hole’s spin and accretion disk orientation.”including the MeerKAT telescope in South Africa.
The particles composing the longer filaments are traveling at nearly the speed of light, and the horizontal ones appear to accelerate thermal material in a molecular cloud, according to the same“We think they must have originated with some kind of outflow from an activity that happened a few million years ago,” Yusef-Zadeh said. “It seems to be the result of an interaction of that outflowing material with objects near it.
Black holes have suffered for their name. They are sometimes presumed to be vacant, inert regions—or at least black box regions where our astrophysical understandings break down. But for all their mysteries—fromThe filaments in and around the Milky Way center are just one of the curiosities that needs more investigation, but clearly are connected to the black hole holding everything together.
