Details 12.8 billion light years from Earth in the galaxy jet

The VLBA image of the Blazer PSO J0309 + 27 is composed of three observations made at different radio speeds. Red is from 1.5 GHz. Green than 5 GHz; And blue from 8.4 GHz. Low-frequency or long-wavelength data shows the amplitude of the object; Medium and high frequency data show small structures that are not visible to VBB at low frequency.

The National Science Foundation (VLBA) SuperShar Radio’s “Vision” has unprecedented detail in a three-quarter-speed jet from the center of the galaxy, which is about 12.8 billion light-years. Earth. The galaxy, dubbed “PSO J0309 + 27”, is the largest galaxy pointing to the Earth, and is the brightest radio beam at this distance and the second brightest X-ray blazer at such a distance.

The brightest radio frequency in this image comes from the right side of the center of the galaxy. The plane is ruled by a huge gravitational force Black hole Moves over the main, and up, to the top left. The jet shown here extends about 1,600 light years, and shows how it works.

At this distance, PSO J0309 + 27 appears to have existed at a time when the universe was less than a billion years old or just over 7% of its current age.

An international team of astronomers led by Christina Spingogo at the University of Bologna in Italy April and April Linn They looked at the galaxy in 2020. Analysis of the material supports some theoretical models of why knives are rarely found in the ancient universe. The researchers reported their results in the journal Astronomy and Astrophysics.
