abstract

We formulate a vibrationally resolved kinetics for molecular hydrogen and its cation in the primordial Universe chemistry. Formation, destruction and relaxation processes for each vibrational level are studied and included as chemical pathways of the present model. The fractional abundance of each vibrational level as a function of the redshift is given: a strong deviation from the Boltzmann distribution is found at low $z$. A discussion of the results is provided, also evaluating the effects of relaxation processes on the level populations. Analytical fits for some LTE rate coefficients are given in the Appendix.

  1. Resolving dense photo-dissociation regions: the structure of photochemical fronts in three-dimensional gas distributions

    astro-ph.GA 2026-08 conditional novelty 7.0 of 10

    A three-dimensional PDR model shows that overlapping H2 dissociation and C+ recombination fronts, plus the arc-like H2 emission seen in the Orion Bar, arise from shadowing by dense clumps in a fractal gas distribution.

  2. Velocity-resolved [O I] 63,145 um, [C II] 158 um, and OH mapping along the Orion BN/KL explosive outflow and irradiated shocks

    astro-ph.GA 2026-05 unverdicted novelty 7.0 of 10

    Velocity-resolved [O I] maps of the Orion BN/KL outflow yield a total luminosity of 86.5 L_sun and line ratios indicating dense (10^5–10^6 cm^-3), warm (~500 K) postshock gas from 30–40 km/s dissociative J-type shocks...
