Evolution of Cosmic Molecular Gas Mass Density From z ~ 0 to z = 1 -1.5
Fumiya Maeda, Kouji Ohta, Akifumi Seko
We try to constrain the cosmic molecular gas mass density at and that in the local universe by combining stellar mass functions of star-forming galaxies and their averag…
Constraint on the inflow/outflow rates in star-forming galaxies at z~1.4 from molecular gas observations
Akifumi Seko, Kouji Ohta, Kiyoto Yabe +5
We constrain the rate of gas inflow into and outflow from a main-sequence star-forming galaxy at z~1.4 by fitting a simple analytic model for the chemical evolution in a galaxy to…
Gas-to-dust ratio in massive star-forming galaxies at z~1.4
Akifumi Seko, Kouji Ohta, Kiyoto Yabe +3
We present results of 12CO(J=2-1) observations toward four massive star-forming galaxies at z~1.4 with the Nobeyama 45~m radio telescope. The galaxies are detected with Spitzer/MIP…
Properties of the Interstellar Medium in Star-Forming Galaxies at z~1.4 revealed with ALMA
Akifumi Seko, Kouji Ohta, Kiyoto Yabe +5
We conducted observations of 12CO(J=5-4) and dust thermal continuum emission toward twenty star-forming galaxies on the main sequence at z~1.4 using ALMA to investigate the propert…
