Very Long Baseline Interferometry with the SKA Observatory

J. F. Radcliffe, J. Yang, Z. Paragi +129

Very Long Baseline Interferometry (VLBI) is a fundamental technique that combines signals from telescopes separated by thousands of kilometres to obtain some of the highest-resolut…

First observations with a GNSS antenna to radio telescope interferometer

Joe Skeens, Johnathan York, Leonid Petrov +5

We describe the design of a radio interferometer composed of a Global Navigation Satellite Systems (GNSS) antenna and a Very Long Baseline Interferometry (VLBI) radio telescope. Ou…

Precise VLBI/GNSS ties with micro-VLBI

Leonid Petrov, Johnathan York, Joe Skeens +3

We present here a concept of measuring local ties between collocated GNSS and VLBI stations using the microwave technique that effectively transforms a GNSS receiver to an element…

Single band VLBI absolute astrometry

Leonid Petrov

The ionospheric path delay impacts single-band very long baseline interferometry (VLBI) group delays, which limits their applicability for absolute astrometry. I consider two impor…

RadioAstron discovery of a mini-cocoon around the restarted parsec-scale jet in 3C 84

T. Savolainen, G. Giovannini, Y. Y. Kovalev +19

We present RadioAstron space-based very long baseline interferometry (VLBI) observations of the nearby radio galaxy 3C84 (NGC1275) at the centre of the Perseus cluster. The observa…
