We report a polarization measurement in prompt î³-ray emission of grb 100826a with the gamma-ray burst polarimeter (gap) aboard the small solar power sail demonstrator ikaros. In this paper, we shortly introduce the solar power sail satellite “ikaros”, and present the ground-based and also in flight calibration data to ensure our measurements of polarization of prompt emission of … Gap has detected 30 cases of grb so far, and only in the 3 cases above, we detected significant polarization.

We report the polarization measurement in prompt î³-ray emission of grb 100826a, grb 110301a and grb 110721a with the gamma-ray burst polarimeter (gap) aboard the small solar power sail … In this paper, we shortly introduce the solar power sail satellite “ikaros”, and present the ground-based and also in flight calibration data to ensure our measurements of polarization of prompt emission of … We report the polarization measurement in prompt î³ -ray emission of grb 100826a, grb 110301a and grb 110721a with the gamma-ray burst polarimeter (gap) aboard the small solar power sail … Our observation strongly indicates that the polarization measurement is a powerful tool to constrain the grb production mechanism, and more theoretical works are needed to discuss the data in more … Ikaros will cruise toward the venus and establish the solar-sail technology. During its cruising phase, we observe grbs and realize an interplanetary network system to determine the direction of grbs …
