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…

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…

The gas streamer G1-2-3 in the Galactic Center

S. Gillessen, F. Eisenhauer, J. Cuadra +61

The black hole in the Galactic Center, Sgr A*, is prototypical for ultra-low-fed galactic nuclei. The discovery of a hand-full of gas clumps in the realm of a few Earth masses in i…

The Milky Way satellite galaxy Leo T: A perturbed cored dwarf

Matias Blaña, Andreas Burkert, Michael Fellhauer +3

The impact of the dynamical state of gas-rich satellite galaxies at the early moments of their infall into their host systems and the relation to their quenching process are not co…
