We present the first interferometric measurement of CO emission (θ ~ 2'') from the ultraluminous infrared galaxy Mrk 273. A total H2 mass of 3.6 × 1010 Msun is inferred from the CO observations, half of which belongs to an extended component with deconvolved size 5.1 × 2.5 kpc. In addition, an unresolved molecular gas complex is found to be coincident with the optical nucleus. The inferred H2 mass, size (R ~ 380 pc), and mean surface mass density (ΣH2 ≥ 4 × 104 Msun pc-3) of this complex, as well as the IR luminosity, are very similar to those …

e report high resolution imaging of the CO (3-2) emission in the luminous infrared source FSC 10214+4724 at z = 2.2853. Maps at resolutions of 2farcs3 × 3farcs0 and 45-90 km s-1 show the CO emission peak coinciding with those of Hα and radio continuum. Two components are identified in the CO emission: an unresolved core and an extended source (~1farcs9 × 4farcs4)—elongated southeast-northwest. The implied size is 9 × 24 kpc for H0 = 75 km s-1 Mpc-1 and q0 = 0.5. The extent of the CO emission is significantly greater than that of either the optical or the …
