  The Madala hypothesis was formulated to explain anomalies in LHC data from
run-1. Subsequently, these anomalies have endured into run-2 and been
strengthened. This makes the analysis of the proposal highly pertinent, and,
since some of the properties of the model are beyond the reach of current
collider data it is also important to determine alternative means of analysis.
Here, we examine the consequences of WIMPs linked to the Madala hypothesis
providing a dark matter candidate and annihilating in the galactic centre of
the Milky-Way and the Andromeda galaxy. These targets have been observed to
have similar gamma-ray spectra by Fermi-LAT and their emissions have been
widely discussed in terms of dark matter annihilation in the literature.
  We show that, when the decay branchings of the hidden-sector mediator in the
Madala hypothesis are assumed Higgs-like, the emissions of Andromeda and the
Milky-Way are not compatible with both being produced by dark matter
annihilation, apart from when a steeply contracted NFW profile is assumed for
the halos or the WIMP has a mass above 1 TeV. Additionally, similar results are
displayed for a wide variety of model independent cases
