The HI content of star-forming galaxies at z = 0.24 (2007)
Lah, Philip, Chengalur, Jayaram N., Briggs, Frank H., Colless, Matthew, De Propris, Roberto, Pracy, Michael B., ...
We use observations from the Giant Metrewave Radio Telescope (GMRT) to measure the atomic hydrogen gas content of star-forming galaxies at z = 0.24 (i.e. a look-backtime of ~3 Gyr). The sample of...

Umeda, Kazuyoshi, Yagi, Masafumi, Yamada, Sanae F., Taniguchi, Yoshiaki, Shioya, Yasuhiro, Murayama, Takashi, ...
We present an optical multicolor-imaging study of the galaxy cluster Abell 521 at $z = 0.25$, using Suprime-Cam on the Subaru Telescope, covering an area of $32 \times 20$ arcmin$^2$ ($9.4 \times 5.8...
A Subaru Search for Lyman$\alpha$ Emitters at Redshift 5.7 (2003)
Ajiki, Masaru, Taniguchi, Yoshiaki, Fujita, Shinobu S., Shioya, Yasuhiro, Nagao, Tohru, Murayama, Takashi, ...
We present the results of a survey for Ly$\alpha$ emitters at $z\approx 5.7$ based on optical narrow-band ($\lambda_{\rm c} = 8150$ \AA ~ and $\Delta\lambda = 120$ \AA), and broad-band ($B$, $R_{\rm...
Are Two z~6 Quasars Gravitationally Lensed ? (2003)
Yamada, Sanae F., Shioya, Yasuhiro, Taniguchi, Yoshiaki, Murayama, Takashi, Ajiki, Masaru, Nagao, Tohru, ...
Several high-z (z > 5.7) quasars have been found in the course of Sloan Digital Sky Survey. The presence of such very high-z quasars is expected to give constraints on early structure formation. On...

Taniguchi, Yoshiaki, Shioya, Yasuhiro, Fujita, Shinobu S., Nagao, Tohru, Murayamaoya, Takashi, Ajiki, Masaru
The 8m class telescopes in the ground-based optical astronomy together with help from the ultra-sharp eye of the Hubble Space Telescope have enabled us to observe forming galaxies beyond redshift...
The discovery of a very narrow line star-forming object at a redshift of 5.66 (2003)
Taniguchi, Yoshiaki, Ajiki, Masaru, Murayama, Takashi, Nagao, Tohru, Veilleux, Sylvain, Sanders, David B., ...
SDSSp J104433.04$-$012502.2 at $z=5.74$ is Gravitationally Magnified by an Intervening Galaxy (2002)
Shioya, Yasuhiro, Taniguchi, Yoshiaki, Murayama, Takashi, Ajki, Masaru, Nagao, Tohru, Fujita, Shinobu S., ...
During the course of our optical deep survey program on L$\alpha$ emitters at $z \approx 5.7$ in the sky area surrounding the quasar SDSSp J104433.04$-$012502.2 at $z=5.74$, we found that a faint...
A Search for Lyman alpha Emitters at Redshift 3.7 (2002)
Fujita, Shinobu S., Ajiki, Masaru, Shioya, Yasuhiro, Nagao, Tohru, Murayama, Takashi, Taniguchi, Yoshiaki, ...
We present the results of a survey for emission-line objects based on optical intermediate-band ($\lambda_{\rm c}$ = 5736 \AA ~ and $\Delta\lambda$ = 280 \AA) and broad-band ($B$, $V$, $R$, and...
A Shock-Induced Pair of Superbubbles in the High-Redshift Powerful Radio Galaxy MRC 0406-244 (2001)
Taniguchi, Yoshiaki, Ohyama, Youichi, Murayama, Takashi, Yoshida, Michitoshi, Kashikawa, Nobunari, Iye, Masanori, ...
We present new optical spectroscopy of the high-redshift powerful radio galaxy MRC 0406$-$244 at redshift of 2.429. We find that the two extensions toward NW and SE probed in the rest-frame...
