Cosmological investigation of multi-frequency VLBI observations of ultra-compact structure in $$z\sim 3$$ z∼3 radio quasars
Abstract In this paper, we use multi-frequency angular size measurements of 58 intermediate-luminosity quasars reaching the redshifts $$z\sim 3$$ z∼3 and demonstrate that they can be used as standard rulers for cosmological inference. Our results indicate that, for the majority of radio-sources in o...
