Stellar interferometry with a K-band integrated optics beam combiner instrument at the CHARA Array - I. First on-sky fringes for CHARIOT
Aline N. Dinkelaker, Kévin Barjot, Nic Scott +8
We present the instrument description and the first on-sky observations for the new CHara ARray Integrated Optics Testbench (CHARIOT) at the CHARA Array. CHARIOT is a 2-telescope p…
Multiparameter quantum bounds for entanglement-assisted aperture synthesis
Kalaga Madhav, Pieter Kok, Nic Scott
Entanglement-assisted optical interferometry promises diffraction-limited imaging over baselines where light cannot be physically combined, but existing theory treats only a single…
NAIR-APREXIS: Enabling photonics-based instruments for long-baseline interferometry and integral-field spectroscopy
L. Labadie, R. J. Harris, K. Madhav +14
The NAIR project -- Novel Astronomical Instrumentation based on photonic light Reformatting -- aims at advancing photonic technologies for infrared long-baseline interferometry and…
Detection and Astrometry of the Ba-Bb Subsystem in Piscium: First Dual-Field Interferometry at the CHARA Array
Narsireddy Anugu, Robert Klement, John D. Monnier +14
We present the first on-sky demonstration of dual-field interferometry at the CHARA Array and the first direct resolution of the inner Ba--Bb subsystem in the bright hierarchical t…
