On the Probable Nature of the “Dark Particle Accelerators” Discovered by HESS

We estimate that the vacuum electric field associated with a spinning Magnetospheric Eternally Collapsing Object MECO[1, 2, 3, 4, 5, 6, 7, 8, 9] could be higher by a factor of ∼ 10 than the corresponding pulsar value because of extreme relativistic Frame Dragging Effect. Thus isolated spinning MECOs could be source of UHE cosmic ray acceleration and VHE γ-ray production. However because of the steeply varying gravitational field close to the surface of the MECO, any signal generated there would be both extremely redshifted and distorted. As a result, there may not be any significant pulsed X-ray or Radio emission from close to the surface, and consequently, the γ-ray source may appear as “Unidentified” and the particle accelerator may appear as “Dark”[10, 11].
