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…
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…
Mid-infrared interferometry with K band fringe-tracking I. The VLTI MIDI+FSU experiment
A. Müller, J. -U. Pott, A. Mérand +11
Context: A turbulent atmosphere causes atmospheric piston variations leading to rapid changes in the optical path difference of an interferometer, which causes correlated flux loss…
PIONIER: a 4-telescope visitor instrument at VLTI
Jean-Baptiste Le Bouquin, J. -P. Berger, B. Lazareff +43
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…
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…
PIONIER: a visitor instrument for the VLTI
J. -P. Berger, G. Zins, B. Lazareff +35
PIONIER is a 4-telescope visitor instrument for the VLTI, planned to see its first fringes in 2010. It combines four ATs or four UTs using a pairwise ABCD integrated optics combine…
