The molecular gas in (some) early type galaxies holds important clues to thehistory and the future of these galaxies. In pursuit of these clues we haveused the BIMA millimeter array to map CO emission in the giant ellipticalgalaxies NGC 83 and NGC 2320 and to search for CO emission from the S0 galaxyNGC 5838. We also present V and R images of NGC 83 and NGC 2320 which tracetheir dust distributions and enable a search for disky stellar structures. Themolecular gas in NGC 83 is well relaxed, but both CO and dust in NGC 2320 showasymmetric structures which may be linked to a recent acquisition of the gas.However, the specific angular momentum distribution of molecular gas in NGC2320 is consistent with that of the stars. Internal origin of the gas (stellarmass loss) cannot, therefore, be ruled out on angular momentum grounds alone.We also consider the evidence for star formation activity and disk growth inthese two elliptical galaxies. Radio continuum and FIR fluxes of NGCv83 suggeststar formation activity. NGC 2320 has bright [O III] emission, but its largeradio/FIR flux ratio and the mismatch between the kinematics of CO and [O III]suggest that the ionized gas should not be attributed to star formation. Theorigin and future of these two CO-rich early type galaxies are thus complex,multi-faceted stories.Comment: accepted to the Astrophysical Journa
