VLBI observations with the SKA-Mid at 12/15 GHz

Year: 2025

Type: article

Abstract: The SKA-Mid plans to support VLBI observations at frequencies up to 15 GHz in the early phase of AA*. The Qitai 110-m and Jingdong 120-m telescopes in China are also going to become operational over the next five years. Moreover, there are more stations available at Ku band in Oceania, Europe, and China. With 32 Gbps VLBI observations at Ku band, one could easily reach an image sensitivity of ~1 µJy/beam. This would allow astronomers to carry out some unprecedented research, such as detecting a ~10 µJy compact transient and gaining an astrometric precision of ~1 µas. Here, we show its scientific advantages and present some initial exploration results (status and future expansion) of the VLBI network at Ku band.
