Dark Matter Signal?

Does dark matter have a signal?  One that can be identified and traced?  Most astrophysicists would say no.  However odd "signals" emanate from the galaxy's center every now and again. 
From the ARTICLE
  • Scientists analyzing high-energy gamma rays emanating from the galaxy's center found an unexplained source of emission that they say is "consistent with some forms of dark matter."  
What makes the task difficult is that scientists do not even know what dark matter is made of.   But theoretically, if dark matter were made up of something called Weakly Interacting Massive Particles this material  could possibly produce gamma rays in ranges that Fermi could detect. 

These signals are far from convincing

Dark matter has mass and exhibits gravity. The Higgs boson might just well be the graviton, but it is too small. Go figure. Dark energy seems to be the opposite of gravity, Eek! I live in this cakamaime universe!
