Although emission in the [S ii] λ6716 forbidden line is commonly assumed to trace ionized gas, we propose state‐selective photoionization of sulfur within neutral regions as a mechanism to explain the 1.5 power scaling between optical forbidden li

Various models of water maser emission in star forming regions, based both on collisional and 6.3 gm radiative pumping mechanisms, require appreciable rates of excitation of water into its first vibrationally excited bending mode. We report the detec

Elevated ratios of [S II]/Hα relative to those typical of H II regions have been used to identify supernova remnants (SNRs) and also characterize the diffuse Galactic background (Reynolds 1985) and gas observed on the large scale in other galaxies (

Far-infrared ionic fine-structure emission lines associated with the large-scale structure of the Galactic ionized medium are interpreted in terms of a heuristic model in which three distinct source morphologies are considered: ionization-bounded H I

The use of SO and SO2 as probes of the dense interstellar medium in the nearby starburst galaxies NGC 253 and M82 is described. Emission in the 99.3 GHz 3(2) - 2(1) rotational transition of SO was detected in NGC 253 and possibly in M82, and upper li

Absorption of orthoformaldehyde (H2CO) toward the giant H II region W51A (G49.5 - 0.4) has been used as a remote probe of the cosmic microwave background (CMB) at a distance of 7.5 kpc. VLA observations of the 6 cm and 2 cm wavelength transitions pro

Within the framework of a semiclassical description, Maxwell's equations coupled to the density matrix equations, the serial three-wave problem comprised of a strong pump (P(32) 9 μm CO2 band) and two emission waves (50 μm and 66 μm) is studied an
