Abstract

We have determined distances and Hubble ratios for galaxies at intermediate redshifts, cz ∼ 10000 to 35000 km s^-1, by applying the CO-line Tully-Fisher relation to our ¹²CO (J = 1-0)-line observations using the Nobeyama 45-m telescope, and near-IR (NlR) 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 H₀ = 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.
