私は宇宙のことを研究している宇宙物理学者です。宇宙はなぜ、どのように膨張しているのか? なぜ大規模構造が存在するのか? 銀河はいつ、どのように生まれて、なぜ様々な形や色をしているのか? ブラックホールはどのように銀河の成長に影響を与えるのか? 宇宙の星形成史はどのようになっているのか? 私はこのような疑問に答えるために、スパコンを使って重力と流体力学の法則を解きながら宇宙全体の構造形成のシミュレーションをしています。これは「数値計算宇宙論」とも呼ばれる比較的新しい研究分野です。

I am an astrophysicist studying the Universe. How and why is the Universe expanding? When and how did galaxies form? Why do they exhibit large-scale structure? Why do they have different colors and morphologies? How do black holes affect galaxy formation? What is the history of cosmic star formation in our Universe? These are the questions that I'm trying to answer. In practice, I use supercomputers to simulate the evolution of the Universe and the matter therein using the laws of gravity and hydrodynamics. This relatively new field of study is sometimes called "Computational Cosmology" or "Numerical Cosmology".
