Do active galactic nuclei convert dark matter into visible particles?

Grib et al. write:

"So it seems that protons of such energies can be
formed at AGN. What is the mechanism of creation
of protons of such high energies at AGN? From our
point of view the natural mechanism for this effect is
conversion of superheavy dark matter into visible one
near AGN."

They also write:

"For t^eff_l≤10²⁷s one could have the observable flow of UHECR from the decay in our Galaxy [5]. But in this case one must get a strong anisotropy in the direction to the center of the Galaxy [6]. However, Auger experiments don’t show such an anisotropy and one must suppose t^eff_l > 10²⁷s."

They are talking about the long lifetime of dark matter particles, and they conclude is bigger than the age of the Universe.

They conclude:

"One must mention that conversion of dark matter into UHECR is effective only for objects with large quantity of the diffusive dark matter close to the black hole. This situation can occur only for AGN and is improbable for ordinary galaxies. From (16) one can see that capture of dark matter by the black hole is proportional to the square of black hole mass, so that the flow of UHECR from black hole of star masses is negligible. We don’t have observation data for the distribution of dark matter at central regions of galaxies with AGN."

They go on to evaluate this distribution from the work of the Mexican physicist Carlos Frenk, brother of a Mexican Health Minister, to conclude.

"So our evaluation leads to reasonable quantity of the accretion of supermassive dark matter particles on the black hole. This dark matter can be considered to be a source of UHECR arising from the decay of supermassive particles on visible matter close to the horizon of the supermassive black hole.

Now let us discuss the possible physical mechanism of conversion of dark matter into visible matter at AGN. It is reasonable to think that AGN differently from other black holes are rapidly rotating supermassive black holes. Then one has the well known Penrose mechanism [12]. The incoming particle in ergosphere decays on two particles, one with negative energy goes inside the black hole while another particle with the opposite momentum and the energy larger than the incoming one goes to the outside space. The condition for the conversion of dark matter superheavy particles into quarks and leptons is great relative energy-momentum in interaction of these particles. This condition can be fulfilled for our Penrose process.

Then the particle with the energy greater than the GU scale going in opposite direction to AGN can collide with the other superheavy particle falling inside and so on. In the result macroscopic amount of dark matter can be ”burned” close to the AGN. So AGN can work as a great cosmical collider."

These authors thus conclude that we could be witnessing a series of extraordinary events, from Penrose's process to dark matter transmutation to light matter.

Heavy man!
