WebbIn other words, the slow-diffusion region around Geminga observed today must be formed in the recent age, if the region is self-excited by Geminga. We assume the electrons injected during the last third of the age of Geminga (228–342 kyr) contribute to the generation of the current slow-diffusion region; this should also be an optimistic assumption … WebbIn the paper we study the possible mechanism for the origin of the slow diffusion. At first, we consider the self-generated Alfvén waves due to the streaming instability of the electrons and positrons released by Geminga. However, even considering a very optimistic scenario for the wave growth, we find this mechanism does not work to account ...
