Extragalactic H2 and its variable relation to CO
نویسنده
چکیده
We derive and discuss the strong dependence on metallicity of the CO to H2 conversion factor X = N (H2)/ICO = 12.2 − 2.5 log [O]/[H] appropriate to extragalactic objects, as well as the weaker dependence found for such objects from interferometer measurements.

Tracing molecular gas mass in extreme extragalactic environments: an observational study
We present a new observational study of the CO(1–0) line emission as an H2 gas mass tracer under extreme conditions in extragalactic environments. Our approach is to study the full neutral interstellar medium (H2, H I and dust) of two galaxies whose bulk interstellar medium (ISM) resides in environments that mark
متن کاملUnderstanding the H2/HI Ratio in Galaxies
We revisit the mass ratio R mol between molecular hydrogen (H2) and atomic hydrogen (HI) in different galaxies from a phenomenological and theoretical viewpoint. First, the local H2mass function (MF) is estimated from the local CO-luminosity function (LF) of the FCRAO Extragalactic CO-Survey, adopting a variable CO-to-H2 conversion fitted to nearby observations. This implies an average H2-densi...
متن کاملMicrowave Assisted Synthesis of Nano Zeolite Seed for Synthesis Membrane and Investigation of its Permeation Properties for H2 Separation
MFI-type zeolite membranes (ZSM-5) were prepared on α-alumina tubular supports and tested for separation of H2/CO mixtures. The effect of pressure and temperature on H2 and CO flows and selectivity was investigated. The best results in this work were obtained with a ZSM-5 membrane prepared over a porous α-alumina tube seeded with zeolite nanocrystals synthesized with m...
متن کاملThe Application of Hybrid RSM/ANN Methodology of an Iron-based Catalyst Performance in Fischer-Tropsch Synthesis
In this research, the performance and kinetics of an iron/manganese oxide catalyst in a fixed-bed reactor by Fischer-Tropsch Synthesis is studied. The range of operating conditions are; P = 1 – 12 bar, T = 513 - 553 K, H2/CO ratio = 1 - 2 and GHSV = 4200 – 7000 ((〖cm〗^3 (STP))/h/g_cat). The effect of these independent variables, on Fischer-Tropsch product were performed by using a statistical m...
متن کاملThe SWS survey for rotational H2 lines in late-type galaxies
We report the first extragalactic detection of the pure rotational H2 S(0) and S(1) lines at 28.2 and 17.0 m in the central 130 pc molecular complex of the nearby Scd galaxy NGC 6946. We deduce a temperature of this gas component of 170 K and a mass of 5 106 M for an ortho/para ratio of 3, corresponding to the ratio of statistical weights. The warm gas is confined to a 500 (135 pc) diameter reg...
