英文摘要
To investigate the origin of cosmic magnetic fields, I studied how we can measure intergalactic magnetic fields. I proposed a observational method which utilizes delayed gamma-rays from gamma-ray bursts and active galactic nuclei. As a result, it was shown that tiny intergalactic magnetic fields can be measured by observing delayed gamma-rays from bright gamma-ray bursts and flares of active galactic nuclei with ongoing gamma-ray telescopes such as Fermi and MAGIC.
