HZRG Meaning and
Definition
-
HzRG stands for High-redshift Radio Galaxy. It refers to a type of celestial object that emits radio waves and is observed at high redshifts in the electromagnetic spectrum. In astronomy, redshift is a phenomenon caused by the motion of celestial objects away from us, causing their light to stretch and appear more towards the red end of the spectrum. Redshift is used to measure the distance and speed of galaxies.
HzRGs are among the most distant and massive galaxies detected in the universe. They are characterized by their strong emission of radio waves, which indicates the presence of powerful jets of charged particles emitted from the central supermassive black hole. These galaxies are typically found at redshifts greater than z = 2 (meaning the light we observe from them was emitted when the universe was more than 10 billion years old).
HzRGs play a significant role in understanding the early universe and the formation and evolution of galaxies. Their immense size and powerful radio jets suggest that they may have a profound impact on their surrounding environments, influencing the formation of stars and other galaxies in the vicinity. The study of HzRGs provides important insights into the processes that occurred during the early stages of galaxy formation and the co-evolution of galaxies and their central black holes.
