We find, similarly to previous work, that gravitational potential fluctuations within the central region of the simulated dwarfs kinematically heat the dark matter particles, lowering the dwarfs' central dark matter density.

In this work, we review, revise and improve upon previous phase-space considerations to obtain lower bounds on the mass of fermionic dark matter particles.

A non-parametric higher-order Jeans analysis method, GravSphere, was recently used to constrain the density profiles of Local Group dwarf galaxies, classifying them into those that are more likely to have an inner dark matter cusp and those that are likely to have a core (Read et al.).

We increase the efficiency of our expansion by allowing the scale length parameter of each disc to be negative.
