| Together with Chinese astronomers from Shanghai (Z. Shen, X. Hong, B. Xia, F. Shu) and Yunnan Astronomical Observatories (Z. Li, Y. Xu), JIVE astronomers (J. Yang/PI, Z. Paragi, L.I. Gurvits, R.M. Campbell) investigated a newly-identified Galactic black hole binary candidate MAXI J1836-194 with the e-EVN and the Chinese VLBI Network. The team successfully detected the low-declination source with a high confidence level in both observations. The source was unresolved, which is in agreement with an AU-scale compact jet (Yang et al. 2012, MNRAS, L66). | Together with Chinese astronomers from Shanghai (Z. Shen, X. Hong, B. Xia, F.
