- Voids: <1nG; filaments: ~0.3 µG; galaxies: ~1 µG; clusters: 10 µG. No detections of B-fields in voids.
- Gamma rays interact with the extragalactic background light (EBL) and create electron-positron pairs, which then cascade down to create more gamma rays. This cascade is then observed with some opening angle. Pair production and inverse Compton … Continue Reading ››
