Examples are III Zw 35 (Pihlstr ̈om et al., 2001), Mrk 231 (Kl ̈ockner et al., 2003 ) and the eastern nuclei of Arp 220 (Rovilos et al., 2003). Molecular circumnuclear disks in OH megamaser sources have ... Typically the lines are of the order of 100 km s−1, but results from single-dish OH megamaser surveys have demonstrated the presence of lines with widths ex- ceeding 300 km s−1 by far (Darling and Giovanelli, 2002a). Even though the bulk of the emission may originate in a disk, ...
