Pseudo-images Z (blue), J (green) and Ks (red) of a region corresponding to the candidate galaxy clusters / groups. The red dashed circle marks the central region of the six arcmin radius, the green lines the positions of the two long slits and the red squares the five galaxies observed with F2. In the right panels, 58 candidate galaxies within the studied region were zoomed in / zoomed out. The side of each square is 20 arcs long. attributed to him: arXiv (2022). doi: 10.48550 / arxiv.2210.16332
Research team members from the Universidad Nacional de San Juan, Universidade Federal do Rio Grande do Sul and Universidad Andres Bello have found evidence of a large extragalactic cluster behind part of the Milky Way. The group has posted a document describing their findings on the arXiv prepress server pending publication in the journal. Astronomy and astrophysics.
Astronomers have long known that part of the night sky is mostly hidden from view due to the galactic bulge. Known as the ‘zone of avoidance’, it makes up about 10% of the dark sky, and researchers are wondering what might be behind it. Because the researchers have so little work to do, the area has not been thoroughly investigated; So we know little about what is hidden. In this new effort, the researchers used a variety of tools to better understand what was hidden from view.
In recent years, scientists have used a variety of tools to explore the area to be avoided. In this new effort, the researchers began to collect all the data collected so far and added additional data using information recently obtained from the VVV survey.
The VVV survey is a project supported by the European Organization for Astronomical Research in the Southern Hemisphere, an intergovernmental research organization. It includes several state-of-the-art multisite research facilities. The investigation involved the investigation of the use of stars infrared radiation instead visible light. Such emissions can travel through gas, dust and starlight in the bulge and reach instruments installed on Earth.
in a studio infrared imagesIn this study, the researchers found that they identified several galaxies outside the Milky Way. Due to their number, researchers believe that together they form what they call a massive extragalactic structure. According to their estimates, there could be up to 58 galaxies in the structure.
