プロフィール

宇宙論的な視点から構造形成・銀河形成の研究を行っている。ダークマターとダークエネルギーに支配されたビッグバン膨張宇宙モデルに於いて、どのように大規模構造・銀河・巨大ブラックホールといったものが成長して来たのかを、宇宙論的流体シミュレーションを用いて調べている。すばる望遠鏡やハッブル宇宙望遠鏡の観測データとシミュレーションを比較することで、現在の構造形成理論と宇宙論モデルに制限をつけ、さらにそれらを発展させることが出来る。

We introduce the AGORA project, a comprehensive numerical study of
well-resolved galaxies within the LCDM cosmology. Cosmological hydrodynamic
simulations with force resolutions of ~100 proper pc or better will be run with
a variety of code platfo...

[abbreviated] Estimating the mass of a supermassive black hole (SMBH) in an
active galactic nucleus (AGN) usually relies on the assumption that the broad
line region (BLR) is virialized. However, this assumption seems invalid in BLR
models that co...

We present the results of a numerical study examining the effect of H_2-based
star formation (SF) model on the rest-frame UV luminosity function and star
formation rate function (SFRF) of z>=6 galaxies, and the implications for
reionization. Using...

It has been shown observationally that star formation (SF) correlates tightly
with the presence of molecular hydrogen (H2). Therefore it would be important
to investigate its implication on galaxy formation in a cosmological context.
In the presen...
