ESO is pleased to announce the Science Verification (SV) for GRAVITY+ Adaptive Optics with Laser Guide Stars on VLTI-UT. The upgraded GRAVITY+ Adaptive Optics (GPAO) offer improved sensitivity and/or performance for the VLTI instruments GRAVITY and MATISSE. For example, under the best atmospheric turbulence conditions, the GRAVITY spectrograph can reach K=19.5 with a fringe tracking source K<13 and a tip-tilt star GRP<17, offering unique opportunities of observations of new classes of astrophysical objects.
