Impacts of the image alignment over frequency for VLBI Global Observing System
Ming H. Xu, Tuomas Savolainen, James M. Anderson +4
The VLBI Global Observing System, which is the next generation of geodetic VLBI and is called VGOS, observes simultaneously at four frequency bands in the range 3.0--10.7 GHz (expe…
Testing the magnetic flux paradigm for AGN radio loudness with a radio intermediate quasar
Wara Chamani, Tuomas Savolainen, Kazuhiro Hada +1
For understanding the diversity of jetted active galactic nuclei (AGN) and especially the puzzling wide range in their radio-loudness, it is important to understand what role the m…
Observable quality assessment of broadband very long baseline interferometry system
Ming H. Xu, James M. Anderson, Robert Heinkelmann +3
The next-generation, broadband geodetic very long baseline interferometry system, named VGOS, is developing its global network, and VGOS networks with a small size of 3--7 stations…
Evidence of the --VLBI position differences being related to radio source structure
Ming H. Xu, Susanne Lunz, James M. Anderson +3
We report the relationship between the --VLBI position differences and the magnitudes of source structure effects in VLBI observations. Because the --VLBI position diff…
The impacts of source structure on geodetic parameters demonstrated by the radio source 3C371
Ming H. Xu, Robert Heinkelmann, James M. Anderson +4
Closure quantities measured by very long baseline interferometry (VLBI) observations are independent of instrumental and propagation instabilities and antenna gain factors, but are…
The source structure of 0642+449 detected from the CONT14 observations
Ming H. Xu, Robert Heinkelmann, James M. Anderson +3
The CONT14 campaign with state-of-the-art VLBI data has observed the source 0642+449 with about one thousand observables each day during a continuous observing period of fifteen da…
