A new powerful radio-loud quasar was detected at a red shift. One of the bright radio quasars identified at a high redshift is called PSO J191.05696. There is a paper on arXiv.org.

Quasars, or quasi-stellar objects (QSOs), are extremely Luminous active galactic nuclei. The redshifts are measured from the strong lines in the spectrum.

Astronomers want to find new high-redshift quasars as they are the most distant compact objects in the observable universe. The mass of black holes in quasars can be estimated with the help of the QSO. The signs of black hole activity in the early universe can be seen in high-redshift QSOs.

A new high-redshift quasar has been discovered by a group of researchers. There is a correlation between the data from three different surveys.

The first observations of PSO J191+86), a powerful jetted PSO, were presented in the paper.

According to the study, PSO J191+86 shows a possible peaked radio spectrum of around 1 GHz in the observed frame. If this turnover is confirmed, it will make the newfound quasar one of the most powerful gigahertz-peaked spectrum sources ever detected.

One of the bright high-redshift radio quasars known to date is PSO J191+86. The population of blazars in the early universe was similar to that of PSO J191+86.

The age of the radio jets of PSO J191+86 is within the range of 150 and 450 years. PSO J191+86 may be one of the youngest sources at a high red shift. The team was able to estimate the size of the quasar using the study.

Further radio observations are proposed by the authors of the paper in order to reveal the nature of PSO J191+86.

There is a powerful radio-loud quasar at arXiv. There is a book titled "arxiv.2210.14946."
