Astronomers found out what's hiding a giant cluster of galaxies

Using the AstroSat space satellite, astronomers explored the central cluster of galaxies known as the Coma cluster. The results of the study were published on the preprint server.

The clusters of galaxies contain up to a thousand galaxy-related gravitational galaxies, which are the largest known gravitational and interconnected structures in the universe and serve as excellent laboratories to study the evolution of galaxies and cosmology.

Coma is one of the richest and most well-explored clusters of galaxies in the adjacent universe, located about 321 million light-years away, with over 1,000 galaxies, and two supergiant elliptical galaxies in the central region, namely, NGC 4874 and NGC 4889.

To shed more light on the properties of this cluster, a group of astronomers led by Smithy Mahajan of the Indian Institute of Scientific Education and Research in Mohali, India, observed it with AstroSat, using a satellite telescope with ultraviolet images to study the central area of Koma in the long-range ultraviolet spectrum.

To begin with, astronomers have studied the image of the central field of Coma. The nature of the other sources remains to be seen.

The study showed that most of the brightest galaxies identified by UVIT are members of the Coma cluster. Moreover, many of the 852 galaxies have been found to be non-traditional morphology in the long-range ultraviolet range of waves. For example, the GMP 2910 galaxy has an impressive narrow tail.
