초록

We report preliminary results of an on-going survey of optically selected barred galaxies with $^{12}CO$(J=1-0) line. The entire sample is composed of about 100 bright barred galaxies ($B_T{\le}13$) with small inclination angle. Most of the galaxies are relatively nearby with receding speed less than 10,000 km/sec. In the first observing run, we have observed central parts of 18 galaxies and detected CO emissions from 5 galaxies (NGC521, 2525, 4262, 4900, and 7479). Most of these galaxies are not observed with CO previously, except for NGC7479 which has been studied at various wavelengths. The peak antenna temperature of detected galaxies ranges from about 30 to 300 mK.
