Stellar Populations of Lyman Alpha Emitters at z = 3 - 4 Based on Deep Large Area Surveys in the Subaru-SXDS/UKIDSS-UDS Field (2009)

Ono, Yoshiaki, Ouchi, Masami, Shimasaku, Kazuhiro, Akiyama, Masayuki, Dunlop, James, Farrah, Duncan, ...

We investigate the stellar populations of Lyman alpha emitters (LAEs) at z=3.1 and 3.7 in 0.65 deg^2 of the Subaru/XMM-Newton Deep Field, based on rest-frame UV-to-optical photometry obtained from...

Large Area Survey for z=7 Galaxies in SDF and GOODS-N: Implications for Galaxy Formation and Cosmic Reionization (2009)

Ouchi, Masami, Mobasher, Bahram, Shimasaku, Kazuhiro, Ferguson, Henry C., Fall, S. Michael, Ono, Yoshiaki, ...

We present results of our large-area survey for z'-band dropout galaxies at z=7 in a 1568 arcmin^2 sky area covering the SDF and GOODS-N fields. Combining our ultra-deep Subaru/Suprime-Cam z'- and...

Structural Transition of Li2RuO3 Induced by Molecular-Orbit Formation (2009)

Miura, Yoko, Sato, Masatoshi, Yamakawa, Youichi, Habaguchi, Tatsuro, Ono, Yoshiaki

A pseudo honeycomb system Li2RuO3 exhibits a second-order-like transition at temperature T=Tc=540 K to a low-T nonmagnetic phase with a significant lattice distortion forming Ru-Ru pairs. For this...

Discovery of a Giant Lya Emitter Near the Reionization Epoch (2008)

Ouchi, Masami, Ono, Yoshiaki, Egami, Eiichi, Saito, Tomoki, Oguri, Masamune, McCarthy, Patrick J., ...

We report the discovery of a giant Lya emitter (LAE) with a Spitzer/IRAC counterpart near the reionization epoch at z=6.595. The giant LAE is found from the extensive 1 deg^2 Subaru narrow-band...
