| Abstract: |
10-m class telescopes have brought a wealth of breakthroughs in
Galactic Center science. They have allowed tantalizing results such
as the measurement of orbits of stars coming close to relativistic
velocities and energetic outbursts in the emission from Sgr A*. To
get more details in the flaring activity of Sgr A* and trace truly
relativistic orbits, a spatial resolution of a few milliarcseconds
only is required. For this purpose, we are currently designing
GRAVITY, a second generation instrument for the VLT Interferometer. |
