XuYi Interferometer Observation Simulator
M. Hadjara, T. Xu, Y. Sun +21
The XuYi Interferometer is the first Chinese long-baseline optical interferometer currently under development by the National Institute of Astronomical Optics and Technology (NIAOT…
BRICS Southern Observatory (BRICS-SO) Project: Invitation to African countries to invest in Chile
Massinissa Hadjara, Amokrane Berdja, Swagat R. Das +6
Recently, the BRICS countries created a promising astronomy consortium (https://www.bricsastronomy.org/), which was joined last year by some emerging countries, including two Afric…
Laboratory characterization of Hierarchical Fringe Tracking
Roxanne Ligi, Stéphane Lagarde, Romain Petrov +7
One of the main limitations in long-baseline interferometry lies in its fringe tracking sensitivity. The challenge is therefore to maximize this sensitivity while minimizing the sp…
Potential and sky coverage for off-axis fringe tracking in optical long baseline interferometry
Abdelkarim Boskri, Romain G. Petrov, Thami El Halkouj +6
The spectacular results provided by the second-generation VLTI instruments GRAVITY and MATISSE on active galactic nuclei (AGN) trigger and justify a strong increase in the sensitiv…
Cophasing the Planet Formation Imager
Romain G. Petrov, Abdelkarim Boskri, Thami Elhalkouj +3
The Planet Formation Imager (PFI) is a project for a very large optical interferometer intended to obtain images of the planet formation process at scales as small as the Hill sphe…
Hierarchical fringe tracker to co-phase and coherence very large optical interferometers
Romain G. Petrov, Abdelkarim Boskri, Yves Bresson +5
The full scientific potential of the VLTI with its second generation instruments MATISSE and GRAVITY require fringe tracking up to magnitudes K>14 with the UTs and K>10 with the AT…
Hierarchical fringe tracking
Romain G. Petrov, Thami Elhalkouj, Abdelkarim Boskri +6
The limiting magnitude is a key issue for optical interferometry. Pairwise fringe trackers based on the integrated optics concepts used for example in GRAVITY seem limited to about…
