Superdiffusion at the Galactic Centre
Pau Amaro Seoane, Kostas Tzanavaris, Reinhard Genzel +14
Tracking S-star cluster orbits around Sgr A* calibrates orbital transport models for space-borne gravitational wave detectors. Standard kinetic theories model this cluster via loca…
Stellar rotation of S301 as a macroscopic gyroscope to test general relativity
Pau Amaro Seoane, Xian Chen, Alejandro Torres-Orjuela +16
Stellar trajectories around the Galactic Center provide a testing environment for general relativity. The intrinsic rotation of these stars evolves under covariant transport in cur…
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
Residing in the center of the Milky Way, Sgr A* is the closest massive black hole (MBH). Its vicinity has allowed measuring individual stellar orbits around it. The stars act as te…
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…
The Dynamics of the Wide-Angle Tailed (WAT) galaxy cluster Abell 562
Percy L. Gomez, Diego Calderon
We present the first in depth dynamical analysis of the archetypal Wide-Angle Tailed (WAT) cluster Abell 562. We have combined Gemini observations with archival data from the liter…
Clump formation through colliding stellar winds in the Galactic Centre
D. Calderón, A. Ballone, J. Cuadra +3
The gas cloud G2 is currently being tidally disrupted by the Galactic Centre super-massive black hole, Sgr A*. The region around the black hole is populated by Wolf-Rayet…
