TL;DR: In this paper, the influence of bar on the distribution of molecular gas in spiral galaxies using the data from a CO(1 - 0) mapping survey of 40 nearby spiral galaxies performed with the Nobeyama 45m telescope is presented.

TL;DR: In this paper, the variation of cloud properties across the spiral arm with a resolution comparable to the size of giant molecular clouds (GMCs) was investigated, and the identified clouds were divided into two categories according to whether they are associated with star formation activity or not.

TL;DR: In this article, high molecular fractions (fmol; ratio of the molecular to total gas surface densities) were found in three of five Virgo spiral galaxies in spite of their low total gas column density, based on 12CO J = 1-0 observations with the Nobeyama 45 m telescope equipped with a multibeam receiver, BEARS.

TL;DR: In this article, the velocities of the maser features with the 45-m telescope of the Nobeyama Radio Observatory were monitored using data form 1995-2006, and the velocity drift rate was detected to be N a =+ 2.57 ˙ 0.04 km s � 1 yr � 1 on the average for 6 systemic features.
