The formation of first molecules, negative Hydrogen ions, and molecular ions in a model of the Universe with cosmological constant and cold dark matter is studied. The cosmological recombination is described in the framework of modified model of the effective 3-level atom, while the kinetics of chemical reactions is described in the framework of the minimal model for Hydrogen, Deuterium, and Helium. It is found that the uncertainties of molecular abundances caused by the inaccuracies of… 

Molecules in the early universe

The formation of first molecules, negative Hydrogen ions, and molecular ions in a model of the Universe with cosmological constant and cold dark matter is studied. The cosmological recombination is

Halos in Dark Ages: Formation and Chemistry

Formation of halos in the dark ages from initial spherical perturbations is analyzed in a four-component universe (dark matter, dark energy, baryonic matter, and radiation) in the approximation of

Thermal and resonant emission of dark age halos in the rotational lines of HeH+

We analyse the thermal emission and resonant scattering of CMB radiation from the dark ages halos in the rotational lines of the helium hydride ion (HeH$^{+}$), one of the first chemical compounds in

Gas and star formation from HD and dust emission in a strongly lensed galaxy

The molecular gas content of high-redshift galaxies is a highly sought-after property. However, H2 is not directly observable in most environments, so its mass is probed through other emission lines

Cosmic Reionization and the First Nonlinear Structures in the Universe

In this introductory chapter, we outline expectations for when and how the hydrogen and helium atoms in the universe turned from neutral to ionized, focusing on the earliest, least well understood

Quantum dynamics studies on the non-adiabatic effects of H + LiD reaction

After the Big Bang, chemical reactions of hydrogen with LiH and its isotopic variants played an important role in the late stage of recombination. Moreover, these reactions have attracted the

Global diabatic potential energy surfaces and quantum dynamical studies for the Li(2p) + H2(X1Σ+g) → LiH(X1Σ+) + H reaction

The global diabatic potential energy surfaces which are correlated with the ground state 1A′ and the excited state 2A′ of the Li(2p) + H2 reaction are presented and the mechanism of the title reaction is investigated.

The chemistry of the early Universe

The process of molecule formation in the primor- dial gas is considered in the framework of Friedmann cosmo- logical models from redshift z =1 0 4 to z =0 . First, a com- prehensive analysis of 87

The Dawn of Chemistry

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 be followed with

The chemistry of deuterium, as well as that of hydrogen and helium, in the postrecombination era of the expanding early universe is presented. A thorough survey of all potentially important gas-phase

Cosmological production of H2 before the formation of the first galaxies

Previous calculations of the pre-galactic chemistry have found that a small amount of H 2 , x[H 2 ] ≡ n[H 2 ]/n[H] ≈ 2.6 x 10 -6 , is produced catalytically through the H-, H 2 + and HeH +

Molecules in the early universe

We present calculations of the formation of astrophysically interesting molecules (H/sub 2/, HD, LiH, and HeH/sup +/) by gas-phase reactions during the postrecombination epoch (redshifts z = 300-30).

Molecular hydrogen in the cosmic recombination epoch

The advent of precise measurements of the CMB anisotropies has motivated correspondingly precise calculations of the cosmic recombination history. Cosmic recombination proceeds far out of equilibrium

Chemistry of heavy elements in the Dark Ages

Context. Primordial molecules were formed during the Dark Ages, i.e. the time between recombination and reionization in the early Universe. They were the constituents of the first proto-stellar

Possible flakes of molecular hydrogen in the early Universe

The thermochemistry of H 2 and HD in non-collapsed, non-reionized primordial gas up to the end of the dark age is investigated with recent radiation-matter and chemical reaction rates taking into

How Exactly Did the Universe Become Neutral?

We present a refined treatment of H, He I, and He II recombination in the early universe. The difference from previous calculations is that we use multilevel atoms and evolve the population of each
