In late 2009 quasar 3C273 experienced a series of strong gamma-ray flares which triggered our 6 cm - 7 mm VLBA follow up observations. We added to our 4 multifrequency epochs four years of 7 mm data in order to trace kinematics of newborn components.
The connection between gamma-ray and mm-wavelength variability is complex in 3C273 and there is no one-to-one correspondence in the lightcurves. I

Detailed studies of the jet-accretion disk connection are essential for a better understanding of the formation and launch of the jets. Water disk masers in the very central region of active galaxies, with the circumnuclear disk being viewed edge-on, provide a unique sample of targets for studying the accretion disk
surrounding the super massive black holes. In this work we investigate the accret

Polarisation studies using mm-VLBI probe the intrinsic linear polarization of relativistic outflows at sub-parsec scales, how uniform is the magnetic field geometry and how does it evolve with time, as well as the presence of recollimation shocks near the core region, and structural changes at the innermost jet. We present preliminary results of the first GMVA observations of highly variable, pol

The proper motion measurements combined with the the radial velocities, are important tools for our understanding of the dynamics and evolution of galaxies in a group environment. One of our nearest group is the M81 group at a distance of 3.63 \pm 0.34 Mpc. It is a fascinating interacting galaxy system containing galaxies M81, M82 and NGC 3077. This work present the proper motions of M81 and M82 g

Owing to their compactness and high brightness, molecular masers are ideal targets for high-angular resolution VLBI. At cm wavelengths, intense maser transitions, in particular the 6.7 GHz CH$_3$OH and the 22.2 GHz H$_2$O lines, are extensively observed in high-mass star forming regions and provide unique diagnostic probes. Multi-epoch VLBI observations can provide the 3D kinematics of the circums
