We combine data from our recent FUSE survey of interstellar molecular hydrogen absorption toward 50 high-latitude AGNs with COBE-corrected IRAS 100 ?m emission maps to study the correlation of infrared cirrus with H2. A plot of the H2 column density versus IR cirrus intensity shows the same transition in molecular fraction, f, as seen with total hydrogen column density, NH. This transition is usually attributed to H2 self-shielding, and it suggests that many diffuse cirrus clouds contain H2 in… Expand

Multiwavelength observations of cirrus clouds in the North Celestial Loop: the transition from atomic to molecular gas
Two potential sites of H 2 formation have been discovered in diffuse gas at high Galactic latitude through examining the far-infrared (FIR) H I ratio and looking for an excess over that expected fromExpand
Multiwavelength observations of cirrus clouds in the North Celestial Loop: a study of the OH emission
New 1665- and 1667-MHz OH observations were made with the Green Bank Telescope at an angular resolution of 7 arcmin of 108 locations over two diffuse gas clouds at high Galactic latitude. A linearExpand
A dynamical transition from atomic to molecular intermediate-velocity clouds
Towards the high galactic latitude sky, the far-infrared (FIR) intensity is tightly correlated to the total hydrogen column density which is made up of atomic (HI) and molecular hydrogen (H$_{2})$.Expand

In this third paper of the series, we continue to investigate the transition between atomic and molecular gas in two potential sites of molecule formation at high Galactic latitude, which we call theExpand
LOW-VELOCITY HALO CLOUDS
Models that reproduce the observed high-velocity clouds (HVCs) also predict clouds at lower radial velocities that may easily be confused with Galactic disk (|z|< 1 kpc) gas. We describe the firstExpand
The Dark Molecular Gas
The mass of molecular gas in an interstellar cloud is often measured using line emission from low rotational levels of CO, which are sensitive to the CO mass, and then scaling to the assumedExpand
Star formation in a diffuse high-altitude cloud?
A recent discovery of two stellar clusters associated with the diffuse high-latitude cloud HRK 81.4-77.8 has important implications for star formation in the Galactic halo. We derive a plausibleExpand
H I-TO-H2 TRANSITIONS AND H I COLUMN DENSITIES IN GALAXY STAR-FORMING REGIONS
We present new analytic theory and radiative transfer computations for the atomic-to-molecular (H I-to-H{sub 2}) transitions and the buildup of atomic hydrogen (H I) gas columns in optically thickExpand
THE ATOMIC-TO-MOLECULAR TRANSITION IN GALAXIES. II: H I AND H2 COLUMN DENSITIES
Gas in galactic disks is collected by gravitational instabilities into giant atomic-molecular complexes, but only the inner, molecular parts of these structures are able to collapse to form stars.Expand
