The European Space Agency's (ESA) large-class mission Jupiter Icy Moons Explorer (JUICE) was launched on 2023 April 14, and started its interplanetary journey towards the Jovian system. The primary science goal of the mission is a complex study of the icy Galilean moons of Jupiter, Ganymede, Europa, and Callisto. One of the eleven scientific experiments of JUICE is the Planetary Radio Interferomet ... More

The new generation of geodetic Very Long Baseline Interferometry (VLBI), VLBI Global Observing System (VGOS), is now regularly observing to produce the best geodetic VLBI data, with a thermal noise level of about 3 ps. It now approaches to the designed observing strategy, i.e., scan lengths of on average 10 seconds and switching time of about 20 seconds. However, the systematic errors due to the a ... More

We report results from the first successful simultaneous 22/43 GHz dual-frequency observing campaign with a joint array of the KVN, VERA, and Yebes 40m RT in 2018. Simultaneous receiving makes it straightforward to apply frequency phase transfer (FPT) and source frequency phase referencing (SFPR) methods, which are essential for overcoming the main challenges of mm-VLBI observations and achievi ...

We present the results of a pilot observation testing the performance of Frequency Phase Transfer (FPT) and Source/Frequency Phase Referencing (SFPR) at 22 and 43 GHz using the Korean VLBI Network (KVN) and the Yebes-40m telescope in Spain, with a baseline length of $\sim$9,000 km. The ultimate goal of this project is to monitor the orbital motion of supermassive black hole binaries (SMBHBs) using ... More

The GLOSTAR galactic plane survey conducted with the VLA and Effelsberg telescopes led to the detection of thousands of compact continuum sources in the Galactic Plane with sizes of less than one arcsecond. We observed 1782 of these compact sources in the galactic longitude range from 28 to 36 degrees with the VLBA to investigate the fraction of sources which are detectable with VLBI and to distin ...

We will present astrometric VLBI studies for OH/IR stars conducted with the Japanese VLBI array VERA (VLBI Exploration of Radio Astrometry). Using several OH/IR stars, we have been explored period-luminosity relation (PLR) in the quite long pulsation period range ($\geq$1000 d). A preliminary result of the new PLR will be presented. We will emphasize advantages of VLBI in parallax measuremen ... More
