Using SatGen and Jeans analyses, the authors find that J-factor modeling choices move Fermi dwarf-galaxy dark matter annihilation limits by a factor of 2–4 and that the highest-J dwarfs are already known and spatially extended.

Semi-analytic Inference of Satellite Densities in the Cold Dark Matter Model Part II. Implications for Dark Matter Indirect Detection Constraints
Using SatGen and Jeans analyses, the authors find that J-factor modeling choices move Fermi dwarf-galaxy dark matter annihilation limits by a factor of 2–4 and that the highest-J dwarfs are already known and spatially extended.
