Long-Lived Positronium and AGN Jets

الملخص EN

We suggest that stable states of positronium might exist in the jets of active galactic nuclei (AGN).

Electrons and positrons are created near the accretion disks of supermassive black holes at the centers of AGN and are accelerated along magnetic field lines while within the Alfvèn radius.

The conditions in this region are ideal for the creation of bound states of positronium which are stable against annihilation.

Traveling at relativistic speeds along the jet, the helical magnetic field enables the atoms to survive for great distances.
