Abstract (from CDS):
New observations with the James Clerk Maxwell Telescope 15 m and the NRO 45 m telescopes show that CO 0.02-0.02 is very bright in the CO (J=3-2) and in the HCN and HCO+ (J=1-0) lines. It appears that the environment may have an unusually high density and temperature, which may be related to the very broad CO line width.
We propose that CO 0.02-0.02 may have been accelerated, heated, and compressed in a series of supernovae shocks that have occurred within the last (3-5)x104 yr.
