The inner rotation curve of the Milky Way

Y. Sofue, M. Kohno

We derived the inner rotation curve (RC) of the Milky Way by applying the terminal velocity method (TVM) to the longitude-velocity diagrams (LVD) made from the large-scale survey d…

A catalog of molecular clouds possibly associated with Galactic infrared bubbles I. The Southern Galactic plane

Mikito Kohno, Yoshiaki Sofue, Yasuo Fukui +1

We have carried out a morphological search for molecular clouds possibly associated with 48 Galactic infrared bubbles with angular radii of $> 1^{'}$ in the southern Galactic plane of…

The CO-to-H $_{2}$ Conversion Factor in the Central Molecular Zone of the Milky Way using CO isotopologues

Mikito Kohno, Yoshiaki Sofue

We performed correlation analyses between the $^{12}$ CO and $^{13}$ CO $J =$ 1-0 line intensities in order to derive the variability of the CO-to-H $_{2}$ conversion factor ($X_{\rm CO,…
