摘要：

We have determined distances and Hubble ratios for galaxies at intermediate redshifts, cz similar to 10000 to 35000 km s(-1), by applying the CO-line Tully-Fisher relation to our (CO)-C-12 (J = 1-0)-line observations using the Nobeyama 45-m telescope, and near-IR (NIR) photometry in the J- and H-bands using the 1.88-m telescope at Okayama Astrophysical Observatory. By averaging the Hubble ratios from the J-band result, we obtained a Hubble constant of H-0 = 60 +/- 10 kms(-1) Mpc(-1). We argue that the CO line-NIR Tully-Fisher relation can be a complimentary method to the other methods for measuring the distances of galaxies at intermediate and high redshifts.
