Abstract

High-spatial-resolution slit scans of the nucleus of Arp 220 are presented along with near-infrared photometry of the nuclear region. A single nucleus is found coincident with the strongest radio peak. The core is resolved to be on the order of 1" (370 pc) in diameter. The photometry of the central region shows a minimum near 3.7 µm which is inconsistent with the near-infrared source being a "classical" nonthermal source, such as 3C 273, embedded in a dust cloud.
