High resolution VLBI observations of relativistic jets are essential to constrain fundamental parameters of current jet formation models. At a distance of 249 Mpc, Cygnus A is a unique target for such studies, being the only powerful FRII radiogalaxy for which a detailed sub-parsec scale imaging of the base of both jet and counter-jet can be obtained. Observing at millimeter wavelengths unveils th

We will report results of GMVA observation of M 87 and progress of the Greenland Telescope Project.
In order to investigate the innermost region of the M 87, we conducted GMVA observation in 2014.
We revealed double ridge structure as is observed by VLBI at low frequency observations.
The measured streamline is reasonably agreed with the previous observations at low frequency.
We will disc

M87, possibly the most studied relativistic jet in active radio galaxies, has been spatially resolved from ten to tens of millions of Schwarzschild radii; it gives a unique opportunity for understanding an AGN jet from birth to termination. Several key issues in AGN jets can be extensively discussed based on multi-frequency radio observations and magnetohydrodynamic (MHD) jet theories toward M87.

The nearby twin-jet system in the low-luminosity active nucleus of NGC 1052 is an ideal target for mm-VLBI studies of jet formation on the smallest accessible scales. At cm-wavelength, NGC 1052 is well known for its prominent emission gap between the two jets, that is caused by free-free absorption in a circumnuclear torus. GMVA observations taken in October 2004 peer through the absorber, reveali

In 2007, the nearby (z=0.049) broad line radio galaxy 3C 111 exhibited a major flux density outburst. Three GMVA millimetre-VLBI observations at 86 GHz covering one year were conducted and allow us to study this outburst with unprecedented image fidelity at highest resolution of ~0.050 mas (~0.05 pc). The outburst led to the appearance of a complex series of plasma components forming an intriguin
