Photonic chip for visible interferometry: laboratory characterization and comparison with the theoretical model
Manon Lallement, Sylvestre Lacour, Elsa Huby +15
Integrated optics are used to achieve astronomical interferometry inside robust and compact materials, improving the instruments stability and sensitivity. In order to perform diff…
Photonic beam-combiner for visible interferometry with SCExAO/FIRST: laboratory characterization and design optimization
Manon Lallement, Elsa Huby, Sylvestre Lacour +15
Integrated optics are used to achieve astronomical interferometry inside robust and compact materials, improving the instrument's stability and sensitivity. In order to perform dif…
An exact solution to the Fourier Transform of band-limited periodic functions with nonequispaced data and application to non-periodic functions
Guy Perrin
The need to Fourier transform data sets with irregular sampling is shared by various domains of science. This is the case for example in astronomy or sismology. Iterative methods h…
VLTI/GRAVITY Observations and Characterization of the Brown Dwarf Companion HD 72946 B
W. O. Balmer, L. Pueyo, T. Stolker +96
Tension remains between the observed and modeled properties of substellar objects, but objects in binary orbits, with known dynamical masses can provide a way forward. HD 72946 B i…
Polarimetry and Astrometry of NIR Flares as Event Horizon Scale, Dynamical Probes for the Mass of Sgr A*
The GRAVITY Collaboration, R. Abuter, N. Aimar +66
We present new astrometric and polarimetric observations of flares from Sgr A* obtained with GRAVITY, the near-infrared interferometer at ESO's Very Large Telescope Interferometer…
Photonic spectro-interferometry with SCExAO/FIRST at the Subaru Telescope: towards H-alpha imaging of protoplanets
Sébastien Vievard, Manon Lallement, Elsa Huby +27
FIRST is a post Extreme Adaptive-Optics (ExAO) spectro-interferometer operating in the Visible (600-800 nm, R~400). Its exquisite angular resolution (a sensitivity analysis of on-s…
