![]() “We found that these filaments are not random but appear to be tied to the outflow of our black hole. We had to do a lot of work to establish that we weren’t fooling ourselves,” added Yusef-Zadeh, who’s also a member of the Center for Interdisciplinary Exploration and Research in Astrophysics. “I was actually stunned when I saw these. ![]() The new study both reinforces and builds upon the earlier findings.įinding the “new population of structures that seem to be pointing in the direction of the black hole” was a surprise, Yusef-Zadeh, a professor of physics and astronomy at Northwestern University’s Weinberg College of Arts and Sciences, said in a news release. Yusef-Zadeh and collaborators also found hundreds more paired and clustered vertical filaments in the same area in 2022, realizing the filaments were likely related to Sagittarius A* activity rather than bursts of supernovae, which they had previously thought. The findings come nearly 40 years after Farhad Yusef-Zadeh, the study’s lead author, and other researchers discovered another population of nearly 1,000 one-dimensional filaments, which are vertical and much larger at up to 150 light-years long each, near the galaxy’s center. ![]() The filaments are relatively short in length, each measuring 5 to 10 light-years. These one-dimensional cosmic threads are hundreds of horizontal or radial filaments - slender, elongated bodies of luminous gas that potentially originated a few million years ago when outflow from Sagittarius A*, the Milky Way’s central supermassive black hole, interacted with surrounding materials, according to a study published Friday in The Astrophysical Journal Letters.
