A probable giant planet imaged in the Beta Pictoris disk
A. -M. Lagrange, D. Gratadour, G. Chauvin +12
Since the discovery of its dusty disk in 1984, Beta Pictoris has become the prototype of young early-type planetary systems, and there are now various indications that a massive Jo…
Near-infrared wavefront sensing for the VLT interferometer
Stefan Hippler, Wolfgang Brandner, Yann Clénet +11
The very large telescope (VLT) interferometer (VLTI) in its current operating state is equipped with high-order adaptive optics (MACAO) working in the visible spectrum. A low-order…
GRAVITY: getting to the event horizon of Sgr A*
F. Eisenhauer, G. Perrin, W. Brandner +45
We present the second-generation VLTI instrument GRAVITY, which currently is in the preliminary design phase. GRAVITY is specifically designed to observe highly relativistic motion…
The FALCON concept: multi-object adaptive optics and atmospheric tomography for integral field spectroscopy. Principles and performances on an 8 meter telescope
Francois Assemat, Eric Gendron, Francois Hammer
Integral field spectrographs are major instruments to study the mechanisms involved in the formation and the evolution of early galaxies. When combined with multi-object spectrosco…
PSF reconstruction for NAOS-CONICA
Yann Clénet, Markus Kasper, Eric Gendron +7
Adaptive optics (AO) allows one to derive the point spread function (PSF) simultaneously to the science image, which is a major advantage in post-processing tasks such as astrometr…
New algorithms for adaptive optics point-spread function reconstruction
Eric Gendron, Yann Clénet, Thierry Fusco +1
Context. The knowledge of the point-spread function compensated by adaptive optics is of prime importance in several image restoration techniques such as deconvolution and astromet…
