Rory O. Bentley, Tuan Do, Andrea Ghez +13
We report the binary fraction of Wolf-Rayet (WR) stars within 0.5~pc of the Galactic center obtained through the longest time-baseline (1994-2024) kinematic study of this populatio…
Interstellar medium phases and abundances in the central parsec: A JWST MIRI/MRS view of the Galactic center
P. Vermot, A. Ciurlo, D. Rouan +8

The JWST Galactic Center Survey -- A White Paper
Rainer Schoedel, Steve Longmore, Jonny Henshaw +111
The inner hundred parsecs of the Milky Way hosts the nearest supermassive black hole, largest reservoir of dense gas, greatest stellar density, hundreds of massive main and post ma…
Tidal phenomena in the Galactic Center: The curious case of X7
Wasif Shaqil, Diego Calderón, Stephan Rosswog +5
Several enigmatic dusty sources have been detected in the central parsec of the Galactic Center. Among them is X7, located at only 0.02 pc from the central super-massive blac…
