Contribution of PRIDE VLBI products to the joint JUICE-Europa Clipper moons' ephemerides solution

Marie S. Fayolle, Dominic Dirkx, Giuseppe Cimo +3

In the coming decade, JUICE and Europa Clipper radio-science will yield the most accurate estimation to date of the Galilean moons' physical parameters and ephemerides. JUICE's PRI…

No apparent superluminal motion in the first-known jetted tidal disruption event Swift J1644+5734

J. Yang, Z. Paragi, A. J. van der Horst +5

The first-known tidal disruption event (TDE) with strong evidence for a relativistic jet -- based on extensive multi-wavelength campaigns -- is Swift J1644+5734. In order to direct…

VLBI observations of the radio quasar J2228+0110 at z=5.95 and other field sources in multiple-phase-centre mode

H. -M. Cao, S. Frey, L. I. Gurvits +5

A patch of sky in the SDSS Stripe 82 was observed at 1.6 GHz with Very Long Baseline Interferometry (VLBI) using the European VLBI Network (EVN). The data were correlated at the EV…

Radio structure of the blazar 1156+295 with sub-pc resolution

W. Zhao, X. -Y. Hong, T. An +4

1156+295 is a flat-spectrum quasar which is loud at radio and gamma-ray. Previous observations of the source revealed a radio morphology on pc to kpc scales consistent with a helic…

The "Number - Flux Density" Relation for Milliarcsecond Structures in Extragalactic Radio Sources

L. I. Gurvits

``Number - flux density'' distributions for total and correlated flux densities at various interferometer spacings in 355 extragalactic radio sources are analysed. Qualitative conc…

VLBI imaging of extremely high redshift quasars at 5 GHz

Z. Paragi, S. Frey, L. I. Gurvits +5

We present very long baseline interferometry (VLBI) images of ten very high redshift (z>3) quasars at 5 GHz. The sources 0004+139, 0830+101, 0906+041, 0938+119 and 1500+045 were ob…
