When did round disk galaxies form?
Tomoe M. Takeuchi, Kouji Ohta, Suraphong Yuma +1
When and how galaxy morphology such as disk and bulge seen in the present-day universe emerged is still not clear. In the universe at , galaxies with various morphology…
The Redshift and Metallicity of the Host Galaxy of Dark GRB 080325 at z=1.78
Tetsuya Hashimoto, Daniel A. Perley, Kouji Ohta +5
We present near-infrared spectroscopy of the host galaxy of dark GRB 080325 using Subaru/MOIRCS. The obtained spectrum provides a clear detection of H emission and marginal [NII…
The gas inflow and outflow rate in star-forming galaxies at
Kiyoto Yabe, Kouji Ohta, Masayuki Akiyama +5
We try to constrain the gas inflow and outflow rate of star-forming galaxies at by employing a simple analytic model for the chemical evolution of galaxies. The sample i…
Constraint on the Gas-to-Dust Ratio in Massive Star-Forming Galaxies at z~1.4
Akifumi Seko, Kouji Ohta, Bunyo Hatsukade +3
We carried out 12CO(J=2-1) observations toward three star-forming galaxies on the main sequence at z~1.4 with the Nobeyama 45m radio telescope. These galaxies are detected with Spi…
