GRAVITY+: reducing non-common-path aberrations for sub-10 μas astrometric accuracy
Quentin Fournier, Guillaume Bourdarot, Frank Eisenhauer +26
GRAVITY is a state-of-the-art instrument for near-infrared astrometric interferometry that routinely achieves astrometric accuracy of 30-100 microarcsecond in its phase-referenced…
Towards an Extended VLTI: Turbulence Characterization for Kilometer-Scale Optical Links at Paranal
B. Neichel, T. Pichon, G. Bourdarot +10
The paper investigates the feasibility of extending the VLTI to kilometer-scale baselines by using free-space optical links with adaptive‑optics pre‑compensation, and proposes a de…
Proof of concept of heterodyne interferometry at 10.6 um using photonic correlation
Tituan Allain, Jean-Philippe Berger, Guillaume Bourdarot +2
The paper demonstrates a laboratory proof‑of‑concept for mid‑infrared heterodyne interferometry at 10.6 µm using a photonic correlator that leverages telecom‑band fiber components,…
Hunting exomoons with a kilometric baseline interferometer
Thomas O. Winterhalder, Antoine Mérand, Sylvestre Lacour +3
Despite numerous search campaigns based on a diverse set of observational techniques, exomoons - prospective satellites of extrasolar planets - remain an elusive and hard-to-pin-do…
GRAVITY+ adaptive optics (GPAO) tests in Europe
Florentin Millour, Guillaume Bourdarot, Jean-Baptiste Le Bouquin +54
We present in this proceeding the results of the test phase of the GRAVITY+ adaptive optics. This extreme AO will enable both high-dynamic range observations of faint companions (i…
Observations of Microlensed Images with Dual-field Interferometry: On-sky Demonstration and Prospects
P. Mroz, S. Dong, A. Merand +57
Interferometric observations of gravitational microlensing events offer an opportunity for precise, efficient, and direct mass and distance measurements of lensing objects, especia…
