Outline of Final Research Achievements

In this study, we aimed to establish high-sensitivity measurement strategies by calibrating the detectors of two CMB polarization observation experiments, GroundBIRD and QUIJOTE, in Tenerife using drones. During the course of this research, a new focal plane detector array was installed on the GroundBIRD telescope. This new detector array is equipped with 161 pixels, seven times more than the previous array, significantly improving the mapping speed. Additionally, demonstration tests were conducted domestically using the programmed flight of drones.

Academic Significance and Societal Importance of the Research Achievements

GroundBIRD実験は、数少ない日本主導のCMB地上望遠鏡で、本研究においてほぼ完成形に至り、サイエンス観測が開始できたことは非常に大きな成果である。また、国内のデモンストレーション試験により、ドローンを用いたビームマッピングの手法を確立することができた。期間内にテネリフェ島の望遠鏡を用いたドローン評価試験は実現しなかったが、近い将来の評価試験実現に向け、確かな手応えを得た。
