AN ATTEMPT AT RADIO OBSERVATION OF Ap STARS, (2005)
Kodaira,Keiichi, Fomalont,Edward B.
Twelve Ap stars were observed with a radio interferometer at 6.2 cm wavelength. An upper limit of radio flux was found for all of the stars. The absence of radio emission indicates a relatively...

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...
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...
ASCA Observations of Three Shakhbazyan's Compact Groups of Galaxies (2000)
Takahashi, Isao, Fukazawa, Yasushi, Kodaira, Keiichi, Makishima, Kazuo, Nakazawa, Kazuhiro, Xu, Haiguang
X-ray observations of three Shakhbazyan's Compact Groups of Galaxies, SCGG 202, SCGG 205, and SCGG 223, are presented for the first time. Extended X-ray emission was detected from SCGG 202 and SCGG...
The Stellar Population of the M31 Spiral Arm Around OB Association A24 (1999)
Kodaira, Keiichi, Vansevicius, Vladas, Tamura, Motohide, Miyazaki, Satoshi
A study of the stellar population of the M31 spiral arm around OB association A24 was carried out based on the photometric data obtained from deep V and JHK imaging. The luminosity function was...
