The Lifetime of Protoplanetary Disks in a Low-Metallicity Environment (2009)
Yasui, Chikako, Kobayashi, Naoto, Tokunaga, Alan T., Saito, Masao, Tokoku, Chihiro
The extreme outer Galaxy (EOG), the region with a Galactic radius of more than 18 kpc, is known to have very low metallicity, about one-tenth that of the solar neighborhood. We obtained deep...
Subaru/MOIRCS Near-Infrared Imaging in the Proto-Cluster Region at z=3.1 (2008)
Uchimoto, Yuka Katsuno, Suzuki, Ryuji, Tokoku, Chihiro, Ichikawa, Takashi, Konishi, Masahiro, Yoshikawa, Tomohiro, ...
We present the results of deep near-infrared imaging observations of the z=3.1 proto-cluster region in the SSA22a field taken by MOIRCS mounted on the Subaru Telescope. We observed a 21.7 arcmin^2...
Star Formation in the Extreme Outer Galaxy: the IMF in a low metallicity environment (2007)
Yasui, Chikako, Kobayashi, Naoto, Tokunaga, Alan T., Saito, Masao, Tokoku, Chihiro
We are conducting a deep near-infrared (NIR) imaging survey of young embedded clusters in the extreme outer Galaxy (hereafter EOG), at the Galactic radius (R_g) of more than 18 kpc. The EOG is an...
Ichikawa, Takashi, Suzuki, Ryuji, Tokoku, Chihiro, Katsuno-Uchimoto, Yuka, Konishi, Masahiro, Yoshikawa, Tomohiro, ...
We present the first measurement of clustering properties of low mass galaxies with a stellar mass down to M_*~10^9 Msun at 1
MOIRCS Deep Survey. I: DRG Number Counts (2006)
Kajisawa, Masaru, Konishi, Masahiro, Suzuki, Ryuji, Tokoku, Chihiro, Uchimoto, Yuka Katsuno, Yoshikawa, Tomohiro, ...
We use very deep near-infrared imaging data taken with Multi-Object InfraRed Camera and Spectrograph (MOIRCS) on the Subaru Telescope to investigate the number counts of Distant Red Galaxies (DRGs)....
