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…
Summary Report on the 2024 African School of Physics Program for Learners
Kétévi A. Assamagan, Abdelkarim Boskri, Kenneth Cecire +6
On April 15-19, 2024, as a part of the eighth African School of Physics, ASP2024, we organized a program for learners from selected high schools in the vicinity of Marrakesh, Moroc…
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…
