Into the central 10 pc of the most distant known radio quasar. VLBI imaging observations of J1429+5447 at z=6.21
S. Frey, Z. Paragi, L. I. Gurvits +2
Context: There are about 60 quasars known at redshifts z>5.7 to date. Only three of them are detected in the radio above 1 mJy flux density at 1.4 GHz frequency. Among them, J1429+…
The most distant radio quasars at the highest resolution
S. Frey, Z. Paragi, . L. I. Gurvits +2
There are about 50 quasars known at redshifts z>5.7 to date. Only three of them are detected in the radio (J0836+0054, z=5.77; J1427+3312, z=6.12; J1429+5447, z=6.21). The highest-…
Large-scale radio nebula around the Ultra-Luminous X-ray Source IC 342 X-1
D. Cseh, C. Lang, S. Corbel +2
We present discovery of a radio nebula associated with the ultraluminous X-ray source (ULX) IC 342 X-1 using the Very Large Array (VLA). Taking the surrounding nebula as a calorime…
High-resolution images of five radio quasars at early cosmological epochs
S. Frey, Z. Paragi, L. I. Gurvits +2
Context: Until now, there have only been seven quasars at z>4.5 whose the high-resolution radio structure had been studied in detail with Very Long Baseline Interferometry (VLBI) i…
Radio interferometric observations of two core-dominated triple radio sources at z>3
D. Cseh, S. Frey, Z. Paragi +2
Aims. We selected two radio quasars (J1036+1326 and J1353+5725) based on their 1.4-GHz radio structure, which is dominated by a bright central core and a pair of weaker and nearly…
