TL;DR: In this paper, the results of the first two 5GHz electronic very-long-baseline interferometry (e-VLBI) observations of the X-ray binary Cygnus X-3 using the European VLBI Network were reported.

TL;DR: In this article, the European very long baseline interferometry (VLBI) network was used to observe a sample of Lyman break analogues (LBAs), nearby (z < 0.3) galaxies with properties similar to the more distant Lyman Break galaxies (LBGs).

TL;DR: In this paper, a review describes the techniques used across the electromagnetic spectrum to detect dual active galactic nuclei (AGN) candidates and proposes new avenues for their search, compared with the state-of-the-art numerical simulations and models for formation of dual and binary AGN.

Abstract: We observed SDSS J0836+0054, the most distant radio-loud quasar known at present ($z=5.774$) with the European Very Long Baseline Interferometry (VLBI) Network at the 5 GHz frequency on 2003 November 4. The source is compact at the milli-arcsecond (mas) angular scale with a flux density of 0.34 mJy. The observations with the Very Large Array (VLA) made on the consecutive day support a conclusion that the radio emission from SDSS J0836+0054 is essentially confined within the central 40 pc. Based on our phase-referenced VLBI observation, we obtained the astrometric position of the source accurate to ~2 mas.
