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…
MATISSE-py: a high-level Python interface for efficient, automated VLTI/MATISSE data reduction
A. Soulain, A. Matter, P. Berio +4
The Multi AperTure mid-Infrared SpectroScopic Experiment (MATISSE) at the Very Large Telescope Interferometer (VLTI) delivers rich mid-infrared interferometric datasets that are re…
Pushing high angular resolution and high contrast observations on the VLTI from Y to L band with the Asgard instrumental suite: integration status and plans
Marc-Antoine Martinod, Michael J. Ireland, Denis Defrère +39
ESO's VLTI has a history of record-breaking discoveries in astrophysics using high-angular resolution instrumentation. Its latest visitor instrument, the Asgard instrumental suite,…
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…
Using VLTI/GRAVITY+ to determine the identity of a third planet candidate in the PDS 70 system
David Trevascus, Wolfgang Brandner, Olga Balsalobre-Ruza +75
Detections of protoplanets are rare and protoplanetary disk features mischaracterized as planets are common. PDS 70 is one of only two stars known to host multiple confirmed protop…
First Resolution of Microlensed Images of a Binary-Lens Event
Zexuan Wu, Subo Dong, A. Mérand +72
We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves sh…
Asgard/NOTT: water vapor and CO atmospheric dispersion compensation system
Romain Laugier, Denis Defrère, Michael Ireland +8
To leverage the angular resolution of interferometry at high contrast, one must employ specialized beam-combiners called interferometric nullers. Nullers discard part of the astrop…
Quasi-Random Frequency Sampling for Optical Turbulence Simulations
A. Berdja, M. Hadjara, M. Carbillet +2
Optical turbulence modelling and simulation are crucial for developing astronomical ground-based instruments, laser communication, laser metrology, or any application where light p…
MATISSE: specifications and expected performances
A. Matter, S. Lagarde, R. G. Petrov +9
MATISSE (Multi AperTure mid-Infrared SpectroScopic Experiment) is the next generation spectro-interferometer at the European Southern Observatory VLTI operating in the spectral ban…
Data reduction for the MATISSE instrument
Florentin Millour, P Berio, M Heininger +15
We present in this paper the general formalism and data processing steps used in the MATISSE data reduction software, as it has been developed by the MATISSE consortium. The MATISS…
