  We consider a simplified model of fermionic dark matter which couples
exclusively to the right-handed top quark via a renormalizable interaction with
a color-charged scalar. We first compute the relic abundance of this type of
dark matter and investigate constraints placed on the model parameter space by
the latest direct detection data. We also perform a detailed analysis for the
production of dark matter at the LHC for this model. We find several kinematic
variables that allow for a clean signal extraction and we show that the
parameter space of this model will be well probed during LHC Run-II. Finally,
we investigate the possibility of detecting this type of dark matter via its
annihilations into gamma rays. We compute the continuum and the line emission
(which includes a possible "Higgs in Space" line) and its possible discovery by
future gamma-ray telescopes. We find that the annihilation spectrum has
distinctive features which may distinguish it from other models.
