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 …

Reconciling the diversity and uniformity of galactic rotation curves with self-interacting dark matter
Galactic rotation curves exhibit diverse behavior in the inner regions while obeying an
organizing principle; ie, they can be approximately described by a radial acceleration …

Hints for a gravitational transition in Tully–Fisher Data
We use an up-to-date compilation of Tully–Fisher data to search for transitions in the
evolution of the Tully–Fisher relation. Using an up-to-date data compilation, we find hints …
