J1145-0033 - the most distant giant radio source?
A. Kuźmicz, E. Kuligowska, M. Jamrozy
We present J1145-0033, a candidate for the most distant (z=2.055) lobe-dominated giant radio quasar, with a projected linear size of 1.34 Mpc. This quasar has both FR II -- type ra…

Giant Radio Sources as a probe of the cosmological evolution of the IGM, II. The observational constraint for the model of the radio-jets propagation through the X-ray halo--IGM interface
E. Kuligowska, M. Jamrozy, D. Koziel-Wierzbowska +1
hree limited samples of high-redshift radio sources of FRII-type are used to constrain the dynamical model for the jets' propagation through the two-media environment: the X-ray em…
