Progress on FORS-Up: the first instrument using ELT technologies
H. M. J. Boffin, V. Baldini, S. Bertocco +21
ESO is in the process of upgrading one of the two FORS (FOcal Reducer/low dispersion Spectrograph) instruments - a multi-mode (imaging, polarimetry, long-slit, and multi-object spe…
FORS-Up: Making the most versatile instrument in Paranal ready for 15 more years of operations
H. M. J. Boffin, F. Derie, A. Manescau +12
The FORS Upgrade project (FORS-Up) aims at bringing a new life to the highly demanded workhorse instrument attached to ESO's Very Large Telescope (VLT). FORS2 is a multimode optica…
An image of the dust sublimation region in the nucleus of NGC 1068
GRAVITY Collaboration, O. Pfuhl, R. Davies +40
We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Inter…
Multiple Star Systems in the Orion Nebula
GRAVITY collaboration, Martina Karl, Oliver Pfuhl +133
This work presents an interferometric study of the massive-binary fraction in the Orion Trapezium Cluster with the recently comissioned GRAVITY instrument. We observe a total of 16…
GRAVITY chromatic imaging of Eta Car's core
GRAVITY Collaboration, J. Sanchez-Bermudez, G. Weigelt +132
Eta Car is one of the most intriguing luminous blue variables in the Galaxy. Observations and models at different wavelengths suggest a central binary with a 5.54 yr period residin…
Optical turbulence profiling with Stereo-SCIDAR for VLT and ELT
J. Osborn, R. W. Wilson, M. Sarazin +11
Knowledge of the Earth's atmospheric optical turbulence is critical for astronomical instrumentation. Not only does it enable performance verification and optimisation of existing…
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…
VLTI status update: a decade of operations and beyond
Antoine Merand, Roberto Abuter, Emmanuel Aller-Carpentier +44
We present the latest update of the European Southern Observatory's Very Large Telescope interferometer (VLTI). The operations of VLTI have greatly improved in the past years: redu…
Improving the astrometric performance of VLTI-PRIMA
J. Woillez, R. Abuter, L. Andolfato +18
In the summer of 2011, the first on-sky astrometric commissioning of PRIMA-Astrometry delivered a performance of 3 m'' for a 10 '' separation on bright objects, orders of magnitude…
The ESPRI project: astrometric exoplanet search with PRIMA I. Instrument description and performance of first light observations
J. Sahlmann, T. Henning, D. Queloz +42
The ESPRI project relies on the astrometric capabilities offered by the PRIMA facility of the Very Large Telescope Interferometer for the discovery and study of planetary systems.…
