Satellites do it, stars do it, and even the entire galaxy does it. Currently, two teams of scientists say that Space Filament is doing that too. These tendrils, which stretch for hundreds of millions of light years, spin like a giant bottle opener.
Space filament is the largest known structure in the universe, Contains most of the mass of the universe (((SN: 1/20/14).these Densely thin strands of dark matter and galaxies connect the cosmic network, Channel matter towards the cluster of galaxies at the end of each strand (SN: 7/5/12).
At the moment of the Big Bang, the matter did not rotate. Then, as stars and galaxies formed, they began to rotate. To date, clusters of galaxies have been the largest known rotating structures. “In the traditional way of thinking about this subject, spin ends here. You can’t really generate large torques,” said Noam Ribeskind, a cosmologist at the Leibniz Institute for Astrophysics in Germany. I am.
Therefore, the discovery that filaments rotate (on a scale that makes the galaxy look like spots of dust) presents a puzzle. “There is no complete theory of how all galaxies rotate, or how all filaments rotate,” said Mark Neylink, a cosmologist at the University of Basque in Bilbao, Spain. I will.
To test the rotation, Neyrinck et al. Use 3D cosmological simulations Velocity of dark matter mass As the mass moves around the filament. He and his colleagues explain their results on June 3 in a treatise posted on arXiv.org. Monthly Notification of the Royal Astronomical Society..Meanwhile, Libeskind and colleagues sought a spin in the real universe, they report on June 14. Nature Astronomy..Team using Sloan Digital Sky Survey Mapped galaxy movement The velocity was measured perpendicular to the filament axis.
The two teams found similar filament rotation speeds, despite different approaches. [indication] You are seeing the same thing. “
Next, researchers want to work on what rotates these huge cosmic structures and how they get started. “What is the process?” Says Libeskind. “Can we understand that?”
