    This paper discusses the emission of gamma rays from a neighboring dwarf galaxy. My understanding is that there is no conventional explanation of gamma ray emission. So there is interest in pursuing a possibility that these emissions are from dark matter interactions.

    'we detect a signal that exceeds expected backgrounds between
    2 10 GeV and is consistent with annihilation of dark matter for particle masses less than a few
    10^2 GeV.'

    Feel free to look further into this for I am not a professional, but perhaps dark matter has anti-matter counter particles that are annihilating with the dark matter as the paper implies. Sorry if this answer is too basic.
