Spatio-kinematical structure of the Galactic Nuclear Stellar Disk revealed in VLBI astrometry of circumstellar masers
Hiroshi Imai, Kohei Kurahara, Huib J. van Langevelde +2
SKA-VLBI astrometry will enable us to measure up to thousands of three dimensional motions of OH masers associated with circumstellar envelopes (CSEs) of OH/IR stars in the Nuclear…
Mapping the Milky Way with Masers
Ye Xu, Kazi Rygl, Huib Jan van Langevelde +10
SKA-VLBI is poised to revolutionize our understanding of the Galactic structure through its unprecedented astrometric precision and sensitivity. As a next-generation facility, it w…
Ultra-Precise Astrometric Search for Exoplanets with SKA-VLBI
Salvador Curiel, MarÃa J. Rioja, Richard Dodson +2
The study of exoplanets is a rapidly developing field, driven by the discoveries of Kepler and TESS, among others. The recent detection of Jovian planetary companions of low-mass s…
Serial MultiView: an efficient approach to mitigating atmospheric spatial-structure errors for VLBI astrometry
Jingdong Zhang, Bo Zhang, Shuangjing Xu +4
Atmospheric propagation errors are a main constraint on the accuracy of Very Long Baseline Interferometry (VLBI) astrometry. For relative astrometry, differential techniques can mi…
