Constraints on the Intergalactic Magnetic Field Strength from γ-Ray Observations of GRB 221009A
Abstract Characteristics of the cascade gamma-ray signal resulting from very-high-energy gamma-ray sources, such as gamma-ray bursts, can be used to constrain the strength and structure of intergalactic magnetic fields (IGMFs). There has been a debate on whether GRB 190114C, the first gamma-ray burst with observed TeV photons, can constrain the …
