Overview
- An international team proposes a fermionic dark matter configuration with a dense central core wrapped by a diffuse halo acting as one continuous mass distribution.
- Statistical comparisons show predicted orbits for S‑stars and nearby G‑sources differ from the black hole model by under about 1%, leaving both scenarios viable with current data.
- The model reproduces the GAIA DR3‑measured Keplerian decline in the Milky Way’s outer rotation curve when combined with known disk and bulge mass.
- Earlier work indicates an accretion‑lit dark matter core can create an Event Horizon Telescope‑like shadow despite the absence of an event horizon.
- The authors highlight next tests focused on photon‑ring signatures and more precise stellar tracking using the GRAVITY instrument and future EHT observations.
