However, the physical properties of absorption-selected galaxies are not well characterised. While emission-selected galaxy surveys are biased towards the most luminous part of the galaxy population, absorption selection is a potentially unbiased galaxy selection technique with respect to luminosity.
The 12CO luminosity is dominated by the high-J linesĪnd is 4 $\times 10^$ and $\kappa_H$ are adequate for global molecular gas estimates. The gas-to-dust-mass ratios are <ġ20 throughout the sample. On average, the ratios of the warm/cool pressure, mass, and 12CO luminosity areĦ0 +/- 30, 0.11 +/- 0.02, and 15.6 +/- 2.7. High-pressure/low-mass component which dominates the luminosity.

Photometric modeling of dust, we modeled full 12CO spectral line energyĭistributions from J=1-0 to J=13-12 with two components of warm and cool CO Nearby infrared-luminous galaxy systems (21 pointings). Molecular gas than that traced by 12CO J=1-0. Spectrometer (FTS), offer an opportunity to study warmer, more luminous Galaxies, newly observable with the Herschel SPIRE Fourier Transform
