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.

The equivalent of four nights has been reserved between January and April 2026 to execute science verification observations in service mode. The call is open on ESO phase 1 and will run until August 12th, at 12:00-noon CEST. Note that per the SV Policy, raw data are immediately public.
