(author), Paragi, Zsolt (author), An, Tao (author), Zhang, Yingkang (author), Cao, Hongmin (author), Sbarrato, Tullia (author)High-redshift radio sources provide plentiful opportunities for studying the formation and evolution of early galaxies and supermassive black holes. However, the number of known radio-loud active galactic nuclei (AGN) above redshift 4 is rather limited. At high redshifts, it appears that blazars, with relativistically beamed jets pointing...journal article 2022

Gabanyi, K.E. (author), Belladitta, S. (author), Frey, S. (author), Orosz, G. (author), Gurvits, L. (author), Rozgonyi, Krisztina (author), An, T. (author), Cao, H (author), Paragi, Z (author), Perger, Krisztina (author)Active galactic nuclei (AGN) have been observed as far as redshift. They are crucial in investigating the early Universe as well as the growth of supermassive black holes at their centres. Radio-loud AGN with their jets seen at a small viewing angle are called blazars and show relativistic boosting of their emission. Thus, their apparently...journal article 2023
