Outline of Annual Research Achievements

本年度は、Atacama Cosmology Telescope Polarimeter (ACTPol)が2014年までに取得したデータに基づき、Sunyaev-Zel’dovich (SZ)効果で発見された銀河団のカタログと、すばる望遠鏡Hyper Suprime-Cam(HSC)が2016年までに取得したデータの銀河形状カタログを用いて、銀河団の弱重力レンズ効果の測定を行い、銀河団質量の推定を行った。まず、HSCの銀河形状の系統誤差を精密に評価し、銀河形状カタログを作成した。このカタログはHSCコラボレーション内で広く使われている。宇宙論的な物質の密度揺らぎや各銀河団の個性を考慮に入れた統計誤差を正確にモデル化し、測光的赤方偏移の誤った評価によって引き起こされる系統誤差の評価などを行った。また、測定データをフィットする際に用いる理論モデルとして、ACTPolのSZ銀河団の選択関数や、SZ信号に基づいて推定された質量と弱重力レンズ効果によって測定された真の質量との関係などを組み込んだ理論モデルを構築した。この時に用いる物質分布のプロファイルとして、Navarro-Frenk-White(NFW)プロファイルやバリオン入りのN体シミュレーションに基づいたプロファイルを用いて、理論モデルの不定性を調べる研究を行った。このモデルを測定データにフィットする事により、SZ銀河団質量と真の銀河団質量の間には有意な違いがあり、それは先行研究と整合的であることを示した。重複制限により、本年度が最終年度となったが、以上の研究を通して、本研究の目的であるHSCとACTを用いた銀河団質量関数による宇宙論の制限に必要なツールはほぼ準備できたと言える。
