A New Constraint on Reionization from Evolution of the Ly $α$ Luminosity Function at $z \sim 6 - 7$ Probed by a Deep Census of $z = 7.0$ Ly $α$ Emitter Candidates to 0.3 $L^{*}$

Kazuaki Ota, Masanori Iye, Nobunari Kashikawa +10

We detect 20 $z = 7.0$ Ly $α$ emitter (LAE) candidates to $L (Ly α) \geq 2 \times 1 0^{42}$ erg s $^{- 1}$ or $0.3$ $L_{z = 7}^{*}$ and in $6.1 \times 1 0^{5}$ Mpc $^{3}$ volume in the Subaru D…

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 $z = 1 - 1.5$ 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…
