Query: Exploring the Potential of the Dark Matter Candidate from the Madala
  Hypothesis with Multi-frequency Indirect Detection   The Madala hypothesis was proposed by members of the Wits-ATLAS group to
account for several anomalies in both ATLAS and CMS data at the LHC. This
hypothesis extends the standard model through the addition of two scalar bosons
and a hidden sector that can provide a dark matter candidate. This hidden
sector interacts with the standard model only through the mediation of one of
these scalars S. The couplings of S are not amenable to investigation in
current collider data and so are assumed to be Higgs-like to reduce the
parameter space of the model. Our previous work (Beck & Colafrancesco 2016) has
shown that these couplings can be limited via indirect dark matter detection
experiments in gamma-rays (for resonant annihilations into S). Here we will
treat the dark matter and S masses independently, and we generalise our
previous work and examine what fraction of the cosmological dark matter
abundance can be accounted for by particles in the hidden sector of the Madala
hypothesis dark matter when these annihilate to standard model products via a
Higgs-like S. We will also extend our gamma-ray analysis of Madala hypothesis
dark matter to include the constraints of diffuse radio data from the Coma
galaxy cluster in addition to the Fermi-LAT gamma-ray data from both this
target and the Reticulum II dwarf galaxy.
  Our analysis indicates that either the Madala hypothesis cannot provide the
bulk of cosmological dark matter, or the S boson cannot be simply Higgs-like.
These apply unless the candidate particle exceeds a mass of 200 GeV. Both these
scenarios may reduce the attractiveness of the hypothesis as the second case
will imply that many free parameters must be added to describe S, greatly
weakening fits for the model. To investigate the full consequences of this
further work will necessitate using larger astrophysical data sets to strongly
constrain details about S.
