Abstract

We used the mm/sub-mm receivers on the James Clerk Maxwell Telescope (JCMT) to observed the CO J=3--2, 2--1 lines in five local, optically powerful AGN and of the J=4--3 line in 3C 293 (a powerful radio galaxy). Luminous CO J=3--2 emission and high CO (3--2)/(1--0) intensity ratios are found in all objects, indicating highly excited molecular gas. In 3C 293, an exceptionally bright CO J=4--3 line which cannot be easily explained given its quiescent star-forming environment and very low AGN X-ray luminosity. In 3C 293, shocks emanating ...
