Abstract

We present latest results and further development of the image reconstruction tool GRAVITY-RESOLVE (G^R), which is specifically designed for Galactic Center observations with the near-infrared phase-referencing VLTI instrument GRAVITY. We show deep images of the Galactic Center in recent years and movies in which the stellar motion around the central massive black hole SgrA* becomes apparent on yet unmatched scales. Moreover, we present a first result of the newly implemented mosaicing method in G^R to jointly reconstruct multiple datasets which have been separately recorded on sky.
