Symmetric Parsec-scale OH Megamaser Structure in Arp 220
Abstract
The parsec-scale OH megamaser emission in the luminous IR galaxy Arp 220 has been imaged in detail using a global VLBI array. Four major emission regions are revealed in the 1667 MHz line, each with complex spatial and velocity structure showing intriguing symmetries.
