Focus of the project is the determination of the transformation parameters between the Gaia data release products and the VLBI CRF during the mission duration of Gaia and beyond. For this purpose, dedicated phase-referencing VLBI observations of radio stars will be planned, applied for at VLBI observing program committees, scheduled and then analyzed. The calibrators for the phase-referencing will be taken from ICRF3 or from the CRF obtained from within the project. This way the optically bright part of Gaia can be aligned indirectly to ICRF3. The optically faint part of Gaia contains a large number of objects that are also included in ICRF3. Thereby, a special challenge is the fact that radio sources and their optical counterparts do not necessarily appear at the same position on the sky. The most precise alignment of both, bright and faint parts of Gaia with the ICRF3 can be obtained based on both methods, thereby providing the basis for the highly accurate determination of the transformation parameters.
The position is part of a joint project with the VLBI Group at Helmholtz Centre Potsdam, GFZ German Research Centre for Geosciences. The project group led by Prof. Harald Schuh (Technische Universität Berlin and Director of GFZ Department 1) and Dr. Robert Heinkelmann (Head of the VLBI group at GFZ) will also include a doctoral researcher. The two project scientists are expected to collaborate closely. The successful applicant will work together within this project group and with other VLBI scientists at GFZ Potsdam.
