Researchers from Tennessee were able to find a new quasistellar object (AQO) - SDSS J022155.26-064916.6.
AQO - active galactic nuclei with a high level of brightness. They produce EM rays that can be observed in radio waves, IR, UV, visible and X-ray wavelengths. They are the brightest and most distant objects that help to study the Universe. Quasars were used to study the large-scale spatial structure and the epoch of reoinization.
The spectrum of SDSS J022155.26-064916.6 calibrated for flux and wavelength in the redshift frame (z = 0.806) with marked emission lines We now know about the position of more than 200,000 quasars, many of whom have noticed in the Sloan Digital Celestial Survey. These are removable and spectroscopic surveys with a redshift where a 2.5-meter telescope is used. He managed to create the most detailed three-dimensional universal map.
Initially, SDSS J022155.26-064916.6 was considered a star with shock rays. Now it is a quasar with a red shift of 0.8. The object was discovered back in 2013, and the true nature was discovered by reducing the spectrum.
Brightness indicator - 19 trillion solar. The absolute value reaches 28, and the distance - 16.7 billion light years.
