Molecular Cloud Evolution. I. Molecular Cloud and Thin Cold Neutral Medium Sheet Formation [PDF]
Astrophysical Journal, 2006 We discuss molecular cloud formation by large-scale supersonic compressions in the diffuse warm neutral medium (WNM). Initially, a shocked layer forms, and within it, a thin cold layer. An analytical model and high-resolution one-dimensional simulations predict the thermodynamic conditions in the cold layer.

Neutral carbon in the diffuse cold neutral medium
2023В работе обсуждается относительная распространенность C I/H2 в диффузной холодной нейтральной межзвездной среде. Используя полуаналитический формализм, мы описываем, как C I/H2 зависит от основных параметров в среде: объемной концентрации, металличности, интенсивности УФ поля и скорости ионизации космическими лучами.

Turbulent dissipation, CH+ abundance, H2 line luminosities, and polarization in the cold neutral medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT In the cold neutral medium, high out-of-equilibrium temperatures are created by intermittent dissipation processes, including shocks, viscous heating, and ambipolar diffusion. The high-temperature excursions are thought to explain the enhanced abundance of CH+ observed along diffuse molecular sightlines.

Extracting the Cold Neutral Medium from H i Emission with Deep Learning: Implications for Galactic Foregrounds at High Latitude [PDF]
Astrophysical Journal, 2020 Abstract Resolving the phase structure of neutral hydrogen (H i) is crucial for understanding the life cycle of the interstellar medium (ISM). However, accurate measurements of H i temperature and density are limited by the availability of background continuum sources for measuring H i absorption.

The cold neutral medium in filaments at high Galactic latitudes
Astronomy and AstrophysicsContext. The H I distribution at high Galactic latitudes has been found to be filamentary and closely related to the far infrared (FIR) in caustics with coherent velocity structures. These structures trace the orientation of magnetic field lines. Aims.
