In astrophysics there will be a lot of studies are going, today we see about the mysterious filament structures at our center of milky way Galaxy.

This Massive cosmic filament structures are comes from the center our Galaxy at supermassive black hole (Sagittarius A*).
Entirely, yusef-zadeh colleagues discovered the new population of these cosmic filaments.

In 1984, yusef zadeh was discovered the magnetized radio filaments in the Galactic center that will be dangling vertically near the black hole.
The black hole of center of our galaxy the newly find study case is much and spreads out radially and horizontally. In that situation the vertical filaments are travel 150 light year heights, then what about horizontal filaments it will be “dots and dashes of Morse code”.
The South African Radio Astronomy Observatory’s (SARAO) MeerKAT telescope, which has enhanced radio astronomy capabilities, identified the new population. The team was studying known vertical filaments when this new population was spotted in the data.
“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. It is satisfying when one finds order in a middle of a chaotic field of the nucleus of our galaxy,” added Yusef-Zadeh.
The differences between the two populations
Aside from being vertical and horizontal to the galactic plane, the filaments exhibit some unique properties.
In comparison to magnetized vertical filaments, the newly discovered horizontal filaments emit thermal radiation. Vertical filaments accelerate particles at close to the speed of light. Horizontal filaments, on the other hand, “accelerate thermal material in a molecular cloud.”
Horizontal filaments are only 5 to 10 light-years long when compared to vertical filaments, which are relatively longer. Vertical filaments wrap around the galaxy’s nucleus, while horizontal threads extend only to one side, pointing toward the black hole.
The authors state that there are still many unknowns regarding the newly identified population, including the origin. “We think they must have originated with some kind of outflow from an activity that happened a few million years ago. It seems to be the result of an interaction of that outflowing material with objects near it,” said Yusef-Zadeh.
Yusef-Zadeh concluded by saying: “Our work is never complete. We always need to make new observations and continually challenge our ideas and tighten up our analysis.”
