A Galactic Graveyard for Dark Matter: The Stellar Towers of the Milky Way as Fossil PBH Scars

We present the discovery of kinematic star towers in Gaia DR3 data (4–20 kpc), revealing laminated stellar structures (∆z ≈ 0.1 kpc) with: • A velocity dispersion drop to σv = 30 km s−1 at 7–8 kpc (Weylcurvature well: Scars [1])• Unmodeled sinusoids (λ = 3.2 kpc) in radial velocities (p = 0.000 vsGaussian)• Phase-coherent oscillations across Solar/Galactic reference frames These patterns match PBH-evaporation scars ([1], Eq.14) and challengeΛCDM’s halo paradigm. Data extracted from GAIA DR3 queries [2] arepublicly available at GitHub.

Abstract

We present the discovery of kinematic star towers in Gaia DR3 data (4–20 kpc), revealing laminated stellar structures (∆z ≈ 0.1 kpc) with: • A velocity dispersion drop to σv = 30 km s−1 at 7–8 kpc (Weylcurvature well: Scars [1])• Unmodeled sinusoids (λ = 3.2 kpc) in radial velocities (p = 0.000 vsGaussian)• Phase-coherent oscillations across Solar/Galactic reference frames These patterns match PBH-evaporation scars ([1], Eq.14) and challengeΛCDM’s halo paradigm. Data extracted from GAIA DR3 queries [2] arepublicly available at GitHub.
