CO Work (in Progress)

This Document Contains the following:
 

  • My plan of attack on the CO data for the key project.
  • A list of fluxes from the literature that Harriet has provided.
  • A list of 30 CO (literature) and C+ fluxes (Key Sample)that are a merger of my list and Harriet's.
  • A complete list of our observations from 3 observing runs (SEST and the 12m)  (Harriet has addition CSO work.)
  • A plot of CO vs. C+ for the 30 objects.



  • The plan of attack for the CO Database construction for the Key project will be as
    follows:

    1) Record all Distant sample measurements taken (below), 12_CO single pointing
    observations, maps, 13_CO single pointings, 13_CO maps.

    2) Record all Distant Sample CO J=1-0 measurements from the literature
    (Finish in June) giving apertures and fluxes.

    3) Display the literature CO 1-0 data for the Nearby sample.

    4) Add in Harriet's High J Observations.

    5) Re-reduce the SEST runs and display.

    6) Re-reduce the NRAO runs and display.

    7) More CSO observations from Harriet.

    8) Future SEST and NRAO data.

    A C+ CO plot.

    A C+ CO plot, normalized by FIR.

    Figure from Lord et al. 1999, showing the ISO C+ [W/m^2] and groundbased CO (J=1-0) [K km/s] fluxes, normalized to the FIR emission (IRAS data), for galaxies from the Key Project on Normal Galaxies (Helou et al. 1999; open circles). Also shown for comparison are the starburst (asterisks) and Ultra-Luminous Infrared Galaxy (ULIRG; filled circles) samples of Luhman et al. (1998, 1999), and the low-luminosity Virgo spirals (open squares) studied by Smith and Madden (1997). Note the Key Project sample spans the full range of observed parameters from quiescent to very active systems, including three objects of moderate luminosity and redshift which may be used as ULIRG analogs.

    Predicted flux ratios from PDR models for the gas density n, and interstellar radiation field intensity G_0 from Stacey et al. 1991 are superposed as the grid of curves. There is some degeneracy in separating various values of n, but G_0 clearly increases from right to left. Normal and starburst galaxies typically fall in the range of 10^2>n>10^4 and 10^2 At the other extreme, elevated C+/FIR and C+/CO ratios in two Virgo spirals are most likely due to low metaliciies (Smith and Madden 1997).
