The high-velocity dark matter halo of the Milky Way in light of the LZ 248 keV event
- Published
- September 18, 2026
- Identifier
- arXiv:2609.21444
Why it is here
Makes the event a probe of the Galactic speed cutoff while showing that halo co-rotation does not simply lower the fastest laboratory-frame particles.
Machine-assisted summary
The author uses IllustrisTNG and FIRE Milky Way analogues to quantify the fastest local dark matter, finding a broad but Standard-Halo-Model-centered maximum-speed range and illustrating how a shorter tail reshapes endothermic fits near the kinematic boundary.
