New 3D star motion analysis uncovers potential cusp-like structure within the dark matter distribution.
- Astronomers used 18 years of Hubble data to map stars' movements in the Draco dwarf galaxy.
- The study offers the most accurate 3D understanding of stellar dynamics in a dwarf galaxy to date.
- Findings suggest a cusp-like dark matter distribution, aligning with existing cosmological models.
- The research reduces assumptions from previous studies by incorporating detailed star and dark matter characteristics.
- Methodologies from this study are being applied to other dwarf galaxies to better understand dark matter properties.
