TL;DR: GRAVITY as discussed by the authors is a new instrument to coherently combine the light of the European Southern Observatory Very Large Telescope Interferometer to form a telescope with an equivalent 130 m diameter angular resolution and a collecting area of 200 m2.

TL;DR: In this paper, the Multi-Conjugate Adaptive Optics Demonstrator (MAD) is used to correct for atmospheric turbulence over a field of view which is much larger than the one typically covered by the existing adaptive optics systems installed on 8m class telescopes.
