Magnetic Structures in Gamma-Ray Burst Jets Probed by Gamma-Ray Polarization
Daisuke Yonetoku, Toshio Murakami, Shuichi Gunji +10
We report polarization measurements in two prompt emissions of gamma-ray bursts, GRB 110301A and GRB 110721A, observed with the Gamma-ray burst polarimeter (GAP) aboard IKAROS sola…

Strict Limit on CPT Violation from Polarization of Gamma-Ray Bursts
Kenji Toma, Shinji Mukohyama, Daisuke Yonetoku +9
We report the strictest observational verification of CPT invariance in the photon sector, as a result of gamma-ray polarization measurement of distant gamma-ray bursts (GRBs), whi…
