VizieR Online Data Catalog: Tracing total molecular gas in galaxies (Madden+, 2020)
Abstract
We have run Cloudy grids to solve for the total molecular hydrogen gas mass particularly for low metallicity environments such as the Dwarf Galaxy Survey. The grids were computed by varying the initial density at the illuminated face of the HII region, nH, and the distance from the source to the edge of the illuminated HII region, the inner radius, rin. The ionization parameter (U) is deduced in the model, based on the input ionizing source, rin and nH. The models are calculated for 5 metallicity bins: Z=0.05, 0.1, 0.25, 0.5 and 1.0 Zȯ, and nH ranging from 10 to 104cm-3. The rin values range from log(rincm)=20.0 to 21.3, in steps of 0.3dex, which, for the various models, covers a range of G0=17 to 11481 in terms of the Habing radiation field. AV and tauCO are calculated for the models. From these models the user can obtain the predicted MH2, [CI], CO (1-0), [CI] and [OI] luminosities from the model output.
