Gas dynamics in dwarf galaxies as testbeds for dark matter and galaxy evolution

F Lelli - Nature Astronomy, 2022 - nature.com
Dwarf galaxies are ideal laboratories to test dark matter models and alternative theories
because their dynamical mass (from observed kinematics) largely outweighs their baryonic …
