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…
Superdiffusion at the Galactic Centre
Pau Amaro Seoane, Kostas Tzanavaris, Reinhard Genzel +14
The paper models the orbital evolution of the S‑star cluster around the Milky Way’s central black hole using a superdiffusive, fractional transport framework that accounts for long…
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…
Stellar rotation of S301 as a macroscopic gyroscope to test general relativity
Pau Amaro Seoane, Xian Chen, Alejandro Torres-Orjuela +16
The paper studies how the rotation of the S301 star near the Galactic Center can act as a macroscopic gyroscope, using its relativistic precession to test general relativity with i…
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,…
The S stars' zone of avoidance in the Galactic center
Aleksey Generozov, Hagai B. Perets, Matteo S. Bordoni +9
This paper investigates the origin and orbital evolution of S stars in the Galactic center using models of binary disruption and relaxation processes. We focus on explaining the re…
