- Astronomers have found a giant luminous shock wave in a moving galaxy
Astronomers have recorded a giant luminous arc almost 1.8 million light-years long, which was generated by a galaxy moving through intergalactic space. This was reported by Universe Today magazine on June 26.
The uniqueness of the image lies in its clarity. Previously, such shocks were recorded only on X-rays in the form of vague outlines, but in the radio range, through the LOFAR review, the structure was seen in as much detail as possible. This was made possible due to the high sensitivity of the equipment to weak radiation at low frequencies.
The discovered structure, called RAD-BAARG, resembles a bow and arrow in shape. Researchers believe that the galaxy is falling into a massive cluster at high speed. It moves faster than sound in the hot gas that fills intergalactic space. As a result, a curved compressed gas front forms in front of it, a phenomenon that scientists call a head shock wave.
According to the publication, radio plasma erupting from the galaxy's black hole appears to highlight this jump, exposing what astronomers have long predicted but almost never could see. Astronomers expect that there will be more such discoveries in the future.
On June 24, Science X magazine reported on the decoding of the signal of the merger of two black holes. According to astrophysicists, for the first time he reached the area of the event horizon — the conditional boundary of a black hole. Scientists have studied the GW250114 object and found that its exceptionally loud signal can be used as a powerful tool for studying the event horizon of a residual black hole.
