Hubble Constant at Intermediate Redshift using the CO-Line Tully-Fisher Relation
Y. Tutui, Y. Sofue, M. Honma +2
We have determined distances and Hubble ratios for galaxies at intermediate redshifts, cz=about 10,000 to 35,000 km/s, by applying the CO-line Tully-Fisher relation to our 12CO (J=…
Sensitive Radio Observations of High Redshift Dusty QSOs
M. S. Yun, C. L. Carilli, R. Kawabe +3
We present sensitive radio continuum imaging at 1.4 GHz and 4.9 GHz of seven high redshift QSOs selected for having a 240 GHz continuum detection, which is thought to be thermal du…
Compatibility of the CO and HI Linewidths Considering the Gas Distribution and Rotation Curves
Yoshinori Tutui, Yoshiaki Sofue
We have examined the trend between CO and HI linewidths by compiling the linewidths of 219 nearby galaxies. The trend is that the CO linewidths of fast rotating galaxies tend to be…
Central Rotation Curves of Spiral Galaxies
Y. Sofue, Y. Tutui, M. Honma +4
We present high-resolution central-to-outer rotation curves for Sb, SBb, Sc, and SBc galaxies. We discuss their general characteristics, particularly their central behavior, as wel…
Nuclear-to-Disk Rotation Curves of Galaxies in the H_alpha and [NII] Emission Lines
Yoshiaki Sofue, Akihiko Tomita, Yoshinori Tutui +2
We have obtained optical CCD spectroscopy along the major axes of 22 nearby spiral galaxies of Sb and Sc types in order to analyze their rotation curves. By subtracting the stellar…
Optical and CO Radio Observations of Poor Cluster Zwicky 1615.8+3505
A. Tomita, H. Maehara, T. T. Takeuchi +4
The cluster Zwicky 1615.8+3505 is considered to be a dynamically young poor cluster. To investigate the morphology and star-formation activity of galaxies under the environment of…
