The Prediction
Now, the Singular Primordial Preon Theory has predicted that Dark Matter would come in the form of particles whose mass are 13.4 GeV.
This prediction was based on the formula "SystemMass ((6-x)/3)*((Wm/4)-um)", where x is the number of preons in the system, Wm is the mass of the W boson and um is the mass of the up quark. In the case of dark matter, the SPP Theory predicts the system to hold 4 preons and so gives the formula the following value: ((6-4)/3)*((80.4/4)-0.0024) = 13.3984 GeV.
The release of this mass energy gives a very specific frequency signature, just like striking a tuning fork gives a very specific tone.
mass energy - frequency converter
To be exact, the frequency released by this predicted dark matter mass energy is 3.2 x 10^24 Hz (that's 3,200,000,000,000 trillion Hertz, or 3.2 YottaHertz).
The miracle peak
It turns out that the observed spectrum of black hole jets features a surprising peak - a peak whose frequency happens to matchprecisely that of the dark matter predicted by the SPP Theory. The spectrum shows an emission whose frequency is ~3.5 x 10^24 Hz - an astonishing 91% match with the prediction. The peak can be seen in the spectrum of quasar 3C66A:
From a paper on the spectrum of blasar 1ES 0806+524:
VERITAS has observed the blasar 1ES 0806+524 for a total 65 hours from November 2006 to April 2008 resulting in the discovery of very-high-energy with a statistical significance of 6.3 sigma. (...)the inverse-Compton peak is located at ~3.5 x 10^24 Hz.

Other instruments such as MAGIC are picking up the same specific signature of 3.2 YHz / 13 GeV.
The synchrotron and inverse Compton peak positions (νsync ≈ 10^16 Hz, νIC ≈10^24 Hz, corresponding to ∼41 eV and∼13GeV) derived for the SED from 2008 (Acciari et al. 2009) and MAGIC observations presented in this paper are located at the same order of frequency.

The same peak position is reported all over the universe, in the jet spectrum of different active black holes and by different instrumentations.

Science community taken by surprise
The origin of the peak came as a mystery to the scientific community, and they assumed that the cause was a process of electron cooling. However, this assumption was proven incomplete when in 2016 black hole jets were discovered to be defeating electron cooling.
New observations of a jet-emitting black hole show astonishing temperatures inside the jets of 10 trillion degrees Kelvin — a toasty 18 trillion degrees Fahrenheit. This new measurement shows that quasars can blow far past the theoretical temperature limit of 100 billion degrees Kelvin (179 billion degrees Fahrenheit), which has scientists puzzled.
Discovery News
Instead of electron cooling, it is quite possible that the observed 3.5 YHz / 13 GeV emission peak is actually caused by dark matter getting crushed in the accretion disk of the black hole, releasing its mass energy in the process.
conclusion
This could very well constitute an important discovery - for the first time ever we may be witnessing the very "resonance" of Dark Matter, the energy it emits as it gets torn apart by the force of black holes. Furthermore, the same peak is observed in various black holes from everywhere in the Universe, giving multiple confirmations of the discovery.
