AMBER, the near-infrared spectro-interferometric three-telescope VLTI instrument
Context: Optical long-baseline interferometry is moving a crucial step forward with the advent of general-user scientific instruments that equip large aperture and hectometric baseline facilities,Expand
PIONIER: a 4-telescope visitor instrument at VLTI
PIONIER stands for Precision Integrated-Optics Near-infrared Imaging ExpeRiment. It combines four 1.8m Auxilliary Telescopes or four 8m Unit Telescopes of the Very Large Telescope InterferometerExpand
Direct constraint on the distance of $\gamma^2$ Velorum from AMBER/VLTI observations
In this work, we present the first AMBER observations, of the Wolf-Rayet and O (WR+O) star binary system y² Velorum. The AMBER instrument was used with the telescopes UT2, UT3, and UT4 on baselinesExpand
First light for GRAVITY: Phase referencing optical interferometry for the Very Large Telescope Interferometer
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 diameter angularExpand
Near-infrared interferometry of eta Carinae with spectral resolutions of 1 500 and 12 000 using AMBER/VLTI
Aims. We present the first NIR spectro-interferometry of the LBV ? Carinae. The observations were performed with the AMBER instrument of the ESO Very Large Telescope Interferometer (VLTI) usingExpand
MAORY: adaptive optics module for the E-ELT
MAORY is one of the four instruments for the E-ELT approved for construction. It is an adaptive optics module offering two compensation modes: multi-conjugate and single-conjugate adaptive optics.Expand
MAORY for ELT: preliminary design overview
MAORY is one of the approved instruments for the European Extremely Large Telescope. It is an adaptive optics module, enabling high-angular resolution observations in the near infrared by real-timeExpand
AMBER : Instrument description and first astrophysical results Special feature Near-infrared interferometry of η Carinae with spectral resolutions of 1 500 and 12 000 using AMBER / VLTI
Aims. We present the first NIR spectro-interferometry of the LBV η Carinae. The observations were performed with the AMBER instrument of the ESO Very Large Telescope Interferometer (VLTI) usingExpand
AMBER : Instrument description and first astrophysical results Special feature Direct constraint on the distance of γ 2 Velorum from AMBER / VLTI observations
Context. Interferometry can provide spatially resolved observations of massive star binary systems and their colliding winds, which thus far have been studied mostly with spatially unresolvedExpand
