Measuring the cophasing state of a segmented mirror with a wavelength sweep and a Zernike phase contrast sensor
Anne-Laure Cheffot, Arthur Vigan, Samuel Leveque +1
The demand for higher resolution telescopes leads to segmented primary mirrors which need to be phased for operation. A phasing sensor applying a wavelength sweep technique provide…
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…
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…
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.…
First results from fringe tracking with the PRIMA fringe sensor unit
J. Sahlmann, R. Abuter, S. Menardi +12
The fringe sensor unit (FSU) is the central element of the phase referenced imaging and micro-arcsecond astrometry (PRIMA) dual-feed facility for the Very Large Telescope interfero…
