Unprecedented change in the position of four radio sources
Oleg Titov, Sándor Frey, Sébastien Lambert +7
Astrometric positions of radio-emitting active galactic nuclei (AGNs) can be determined with sub-milliarcsec accuracy using very long baseline interferometry (VLBI). The usually sm…
J2102+6015: a young radio source at z = 4.575
Yingkang Zhang, Tao An, Sándor Frey +7
Jets of high-redshift active galactic nuclei (AGNs) can be used to directly probe the activity of the black holes in the early Universe. Radio sources with jets misaligned with res…
Testing General Relativity with geodetic VLBI: what profit from a single, specially designed experiment?
Oleg Titov, Anastasiia Girdiuk, Sebastien Lambert +15
Context. We highlight the capabilities of the geodetic VLBI technique to test General relativity in the classical astrometric style, i.e., measuring the deflection of light in the…
Current status of Shanghai VLBI correlator
Wu Jiang, Zhiqiang Shen, Fengchu Shu +2
Shanghai Astronomical Observatory has upgraded its DiFX cluster to 420 CPU cores and a 432-TB storage system at the end of 2014. An international network connection for the raw dat…
Testing of General Relativity with Geodetic VLBI
O. Titov
The geodetic VLBI technique is capable of measuring the Sun's gravity light deflection from distant radio sources around the whole sky. This light deflection is equivalent to the c…
