Posterior distributions of m22 from Dragonfly 44 (orange histogram) compared with constraints from the literature. A lower bound of ﹩{m}_{22}\gtrsim 20﹩ from modeling of the Lyα forest (see sources in text) is shown by the gray dashed line, with the gray shaded region showing the range of lower bounds found in the literature. The constraint from dSph galaxies (Chen et al. 2017) is shown by the yellow solid line. We see that both inferences on m22 from Dragonfly 44 are consistent with the dSph constraints, but they are in tension with the Lyα constraint. Only ∼10% of samples lie to the right of the Lyα lower bound.
