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…

S301 and friends: Measuring the spin of Sgr A*

T. Piran, P. Amaro-Seoane, B. Aytac +15

The discovery of S301 (GRAVITY Collaboration et al., 2026) with pericenter distance rp= 280rg and eccentricity e=0.9825, opens the prospect of measuring the spin parameter of Sgr A…

Discovery of a star sensitive to the spin of Sgr A*

K. Abd El Dayem, R. Abuter, N. Aimar +85

The paper reports the discovery of a faint main‑sequence star (S301) on an 8.7‑year, highly eccentric orbit around the Milky Way’s central black hole, whose high velocity makes its…
