Astrophysicists made a giant quantum vortex for studying black holes

The superfluid helium (He II), utilized in the new experiment, is generally accustomed to fast-cooling objects best. Hence, the authors of the study discovered a new possibility for He II simulation of a curved space-time in the presence of a black hole. Black hole is a region of space-time in which gravity is so powerful that nothing, including light quanta, can escape. The regions are created by the enhanced implosion of the star in its perishing stage. In the center of our galaxy, the Milky Way, there is the Sagittarius A* black hole. It is 4 million times more massive than the Sun. Since supermassive bodies do not emit light, they have to examine black holesphysicists:

The way the curvature of the cosmos behaves. “Therefore, the photograph of the M87 black hole, or rather its silhouette – the hot disk of gas and dust that M87 attracted – publishe d in 2019 by the Event Horizon Telescope, and recently the astrophysicists received a much more qualitative analogue. . Meanwhile, astrophysicists published their work in the journal Nature.

To study the interaction of black holes with their environment, the authors of the study created a simulation of the curvature of space using a rotating superfluid such as He II.

A propeller in which, as a result of its rotation, cooled He II rotated in the experimental zone. The process of such rotation resulted in the formation of quantum vortices . During the increasing speed of the propeller, an expanding hollow vortex nucleus was generated . Quantification was used in astrophysics in terms of their studies when they sought to evaporate the black holes they had conceived experimentally. In this case, the vortex core was fierce outside the experimental area, and the scientists observed only vortex flows. Additionally, the quantum vortices in He II generated a certain velocity field pop along, which determined the spreading of small waves on the liquid surface.
