[1][2] TXS 1545-234 is classified as a typical brighten Fanaroff-Riley Class II radio galaxy[3] with double hot spots, making it a common phenomenon.
Other factors for having double hot spots in TXS 1545–234, are change of ejection axis from the galaxy's central engine, or by its jet-cloud interaction.
[9] Such USS sources that were studied by researchers, found out there is a strong statistical relationship between its spectral index and the redshift.
[11] From these results, all three radio galaxies show signs of high gas metallicity closer to or higher compared the solar metallicities (i.e., Z ≳ Z⊙), suggesting HzRGs are z ~ 3 are chemically maturing in the early universe, when the cosmic age was only ~2 Gyr,[11] where the average and standard deviation of stellar mass in sample of galaxies such as 4C +23.46 and 4C +40.36 are (2.7 ± 1.3) × 1011 M⊙.
[14][15] The results are shown to consistent with some previous studies,[16] but obtained with only fewer assumptions in the photoionization model.
