Description
I will review the techniques of the measurement of optical / infrared extragalactic background light (EBL) and of intergalactic magnetic fields (IGMF) using the effect of absorption of very-high-energy gamma-rays in the intergalactic medium. I will summarise the existing constraints on both EBL and IGMF and discuss perspectives of improvement of the measurements with the next generation gamma-ray telescopes.
