EGMF strength regimes for no-cascade, pair-halo, and MBC development.
Regime number | I | II | III |
characterised by | synchrotron losses | 2πrg ≪ λIC | 2πrg ≫ cτIC |
|
|||
EGMF strength | B > 3 × 10-6 G | 10-7G > B > 10-12 G | B < 10-14 G |
Synchrotron losses | dominate over IC losses | negligible | negligible |
Electromagnetic cascades | no cascade | pair haloes | magnetically broadened cascades |
Notes. The effects of synchrotron losses for multi-TeV electrons in different EGMF strengths are summarised. λIC and τIC represent the mean free path and cooling time for inverse Compton interactions with the CMB, respectively.
