Milliarcsecond-resolution Radio-imaging Survey of Blazar Candidates at 4 < z < 5.4

We present a milliarcsecond-resolution radio survey of 17 high-redshift (4 ≤ z ≤ 5.4) blazar candidates observed with the European Very Long Baseline Interferometry (VLBI) Network at 5 GHz. The primary objective of this study was to investigate the nature of these distant active galactic nuclei (AGN...
