Within the precise cosmological framework provided by the Λ-cold dark matter model and
standard Big Bang nucleosynthesis, the chemical evolution of the pregalactic gas can now …

This is a summary of the 2013 release of the plasma simulation code Cloudy. Cloudy
models the ionization, chemical, and thermal state of material that may be exposed to an …

Molecular collisions are of fundamental importance in understanding intermolecular
interaction and dynamics. Its importance is accentuated in cold and ultra-cold collisions …

Cosmic-ray and X-ray heating are derived from the electron energy-loss calculations of
Dalgarno, Yan, and Liu for hydrogen–helium gas mixtures. These authors treated the …

We report a new full-dimensional potential energy surface (PES) for the inelastic scattering
between ro-vibrationally excited H2 molecules. The new PES is based on 39,462 multi …

Molecular cooling is essential for studying the formation of substructure of dissipative dark-
matter halos that may host compact objects such as black holes. Here, we analyze the …

As the most abundant molecule in the universe, collisions involving H2 have important
implications in astrochemistry. Collisions between hydrogen molecules also represent a …

The H2+ H2 system has long been considered a benchmark system for ro-vibrational energy
transfer in bimolecular collisions. However, most studies thus far have focused on collisions …

The spherical version of the hydrogen intermolecular potential\rm P recently determined in
ab initio calculations by Patkowski et al. was used to calculate the viscosity and thermal …

A novel rovibrationally resolved collisional-radiative model of molecular hydrogen that
includes 4,133 rovibrational levels for electronic states whose united atom principal …
