A Large Molecular Gas Reservoir in the Protocluster SPT2349−56 at z = 4.3

A Large Molecular Gas Reservoir in the Protocluster SPT2349−56 at z = 4.3

We present Atacama Compact Array (ACA) Band-3 observations of the protocluster SPT2349−56, an extreme system hosting >10 ultraluminous infrared galaxies (ULIRGs; L _IR  ≳  10 ^12 L _⊙ ) in a 200 kpc diameter region at z  =  4.3, to study its integrated molecular gas content via CO(4–3) and the lo...
