Abstract:We present ∼0. ′′ 3 (114 pc) resolution maps of [C I] 3 P 1 -3 P 0 (hereafter [C I] (1-0)) and 12 CO (1-0) obtained toward Arp 220 with the Atacama Large Millimeter/submillimeter Array. The overall distribution of the [C I] (1-0) emission is consistent with the CO (1-0). While the [C I] (1-0) and CO (1-0) luminosities of the system follow the empirical linear relation for the unresolved ULIRG sample, we find a sublinear relation between [C I] (1-0) and CO (1-0) using the spatially-resolved data. We measure the… Show more
