Constraint on the gas-to-dust ratio in massive star-forming galaxies at z ∼ 1.4

Iono, Daisuke; Hatsukade, Bunyo; Ohta, Kouji +3 more

We carried out ¹²CO (J = 2-1) observations toward three star-forming galaxies on the main sequence at z ∼ 1.4 with the Nobeyama 45 m radio telescope. These galaxies have been detected with Spitzer/MIPS in 24 µm, Herschel/SPIRE in 250 µm and 350 µm; their gas metallicity, derived from optical emission line ratios based …
