First Light for the GRAVITY+ Adaptive Optics: Extreme Adaptive Optics for the Very Large Telescope Interferometer
GRAVITY+ Collaboration, :, F. Allouche +137
GRAVITY+ improves by orders of magnitude the sensitivity, sky-coverage and contrast of the Very Large Telescope Interferometer (VLTI). A central part of this project is the develop…
GRAVITY+ Wavefront Sensors: High-Contrast, Laser Guide Star, Adaptive Optics systems for the VLTI
G. Bourdarot, F. Eisenhauer, S. Yazıcı +53
We present the Wavefront Sensor units of the Gravity Plus Adaptive Optics (GPAO) system, which will equip all 8m class telescopes of the VLTI and is an instrumental part of the GRA…
VLTI Unit Telescope coudé train vibration control upgrade for GRAVITY+
Romain Laugier, Julien Woillez, Denis Defrère +15
Scaling up interferometry to 8m collectors should smooth-out the optical piston perturbations and allow a slow fringe tracker to obtain high precision correction on faint targets.…
High contrast at short separation with VLTI/GRAVITY: Bringing Gaia companions to light
N. Pourré, T. O. Winterhalder, J. -B. Le Bouquin +173
Since 2019, GRAVITY has provided direct observations of giant planets and brown dwarfs at separations of down to 95 mas from the host star. Some of these observations have provided…
GRAVITY+ Wide: Towards hundreds of z 2 AGN
A. Drescher, M. Fabricius, T. Shimizu +34
As part of the GRAVITY project, the near-infrared beam combiner GRAVITY and the VLTI are currently undergoing a series of significant upgrades to further improve the performa…
GRAVITY faint: reducing noise sources in GRAVITY with a fast metrology attenuation system
F. Widmann, S. Gillessen, T. Ott +28
With the upgrade from GRAVITY to GRAVITY the instrument will evolve into an all-sky interferometer that can observe faint targets, such as high redshift AGN. Observing the fain…
Characterisation of ALPAO deformable mirrors for the NAOMI VLTI Auxiliary Telescopes Adaptive Optics
Jean-Baptiste Le Bouquin, Jean-Philippe Berger, Jean-Luc Beuzit +12
The Very Large Telescope Interferometer Auxiliary Telescopes will soon be equipped with an adaptive optics system called NAOMI. The corrective optics deformable mirror is the comme…
First Light for GRAVITY: Phase Referencing Optical Interferometry for the Very Large Telescope Interferometer
GRAVITY Collaboration, R. Abuter, M. Accardo +130
GRAVITY 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 di…
The 2nd Generation VLTI path to performance
Julien Woillez, Jaime Alonso, Jean-Philippe Berger +12
The upgrade of the VLTI infrastructure for the 2nd generation instruments is now complete with the transformation of the laboratory, and installation of star separators on both the…
An overview of the mid-infrared spectro-interferometer MATISSE: science, concept, and current status
A. Matter, B. Lopez, P. Antonelli +104
MATISSE is the second-generation mid-infrared spectrograph and imager for the Very Large Telescope Interferometer (VLTI) at Paranal. This new interferometric instrument will allow…
L'-band AGPM vector vortex coronagraph's first light on VLT/NACO: Discovery of a late-type companion at two beamwidths from an F0V star
D. Mawet, O. Absil, C. Delacroix +20
Context. High contrast imaging has thoroughly combed through the limited search space accessible with first-generation ground-based adaptive optics instruments and the Hubble Space…
GRAVITY: a four-telescope beam combiner instrument for the VLTI
S. Gillessen, F. Eisenhauer, G. Perrin +60
GRAVITY is an adaptive optics assisted Beam Combiner for the second generation VLTI instrumentation. The instrument will provide high-precision narrow-angle astrometry and phase-re…
