Astrometric effects of non-uniform telescope throughput
M. Gai, R. Cancelliere
In real telescopes, the optical parameters evolve with time, and the degradation is often not uniform. This introduces variations in the image profile and therefore photo-centre di…
System overview of the VLTI Spectro-Imager
L. Jocou, J. P. Berger, F. Malbet +30
The VLTI Spectro Imager project aims to perform imaging with a temporal resolution of 1 night and with a maximum angular resolution of 1 milliarcsecond, making best use of the Very…
Fringe Tracker for the VLTI Spectro-Imager
L. Corcione, D. Bonino, D. F. Busher +5
The implementation of the simultaneous combination of several telescopes (from four to eight) available at Very Large Telescope Interferometer (VLTI) will allow the new generation…
Milli-arcsecond astrophysics with VSI, the VLTI spectro-imager in the ELT era
F. Malbet, D. Buscher, G. Weigelt +49
Nowadays, compact sources like surfaces of nearby stars, circumstellar environments of stars from early stages to the most evolved ones and surroundings of active galactic nuclei c…
An efficient PSF construction method
M. Gai, R. Cancelliere
Image computation is a fundamental tool for performance assessment of astronomical instrumentation, usually implemented by Fourier transform techniques. We review the numerical imp…
A simple beam combination for stellar interferometry
E. N. Ribak, M. Gai, D. Loreggia +1
In stellar interferometry, image quality improves significantly with the inclusion of more telescopes and the use of phase closure. We demonstrate, using first coherent and then pa…
