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…
GRAVITY acquisition camera: characterization results
Narsireddy Anugu, Paulo Garcia, Antonio Amorim +10
GRAVITY acquisition camera implements four optical functions to track multiple beams of Very Large Telescope Interferometer (VLTI): a) pupil tracker: a lenslet images…
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…
GRAVITY: the VLTI 4-beam combiner for narrow-angle astrometry and interferometric imaging
N. Blind, F. Eisenhauer, S. Gillessen +23
GRAVITY is the second generation Very Large Telescope Interferometer instrument for precision narrow-angle astrometry and interferometric imaging in the Near Infra-Red (NIR). It sh…
GRAVITY: beam stabilization and light injection subsystems
O. Pfuhl, M. Haug, F. Eisenhauer +9
We present design results of the 2nd generation VLTI instrument GRAVITY beam stabilization and light injection subsystems. Designed to deliver micro-arcsecond astrometry, GRAVITY r…
