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 clouds. Standard Big Bang nucleosynthesis predicts the abundances of hydrogen, helium, lithium, beryllium, and their isotopes in the early Universe. Heavier nuclei such as carbon, nitrogen, or oxygen are only formed in trace amounts. In nonstandard Big Bang nucleosynthesis models, it is possible to… 
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
Light element production in the big bang and the synthesis of heavy elements in 3D MHD jets from core-collapse supernovae
In this dissertation we present the main features of a new nuclear reaction network evolution code. This new code allows nucleosynthesis calculations for large numbers of nuclides. The main results
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
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
Initial Li Abundances in the Proto-Galaxy and Globular Clusters Based upon the Chemical Separation and Hierarchical Structure Formation
The chemical separation of Li+ ions induced by a magnetic field during the hierarchical structure formation can reduce initial Li abundances in cosmic structures. It is shown that cosmological
The first spectral line surveys searching for signals from the dark ages
Aims. Our aim is to observationally investigate the cosmic Dark Ages in order to constrain star and structure formation models, as well as the chemical evolution in the early Universe. Methods.
Radiative cooling functions for primordial molecules
Cooling of primordial gas plays a crucial role in the birth of the first structures in our Universe. Due to the low fractional abundance of molecular species at high redshifts, spontaneous emission
A comprehensive chemistry of the highly deuterated species D2 ,D + ,D 2H + , and D + in the early universe is presented. Fractional abundances for each are calculated as a function of redshift z in
Six Phases of Cosmic Chemistry
The article presents a conceptually unified, quantitative account of the development of chemical phenomena throughout the cosmic history, with a detailed discussion of the cosmological,
On the Relative Abundance of LiH and LiH+ Molecules in the Early Universe: New Results from Quantum Reactions
The relative efficiencies of the chemical pathways that can lead to the destruction of LiH and LiH+ molecules, conjectured to be present in the primordial gas and to control molecular cooling


The Deuterium Chemistry of the Early Universe
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
Molecular fluorine chemistry in the early Universe
Some models of Big Bang nucleosynthesis suggest that very high baryon density regions were formed in the early Universe, and generated the production of heavy elements other than lithium such as
The Formation and Fragmentation of Primordial Molecular Clouds
Many questions in physical cosmology regarding the thermal history of the intergalactic medium, chemical enrichment, reionization, etc., are thought to be intimately related to the nature and
Enhanced heavy-element formation in baryon-inhomogeneous big bang models
Author(s): Jedamzik, K; Fuller, GM; Mathews, GJ; Kajino, T | Abstract: We show that primordial nucleosynthesis in baryon-inhomogeneous big-bang models can lead to significant heavy-element production
Does Deuterium Enable the Formation of Primordial Brown Dwarfs?
It is shown that almost all deuterium can be converted to HD within the age of the universe at the collapsed redshift in the case of a cloud that has a virial temperature of approximately 106 K and collapses at z>1.
Production of heavy elements in inhomogeneous cosmologies
The incorporation of quantum chromodynamics into big bang cosmology predicts that the universe shifted from a quark-gluon plasma to a meson gas when it was roughly 10 μs old. If this change is due to
Uncertainties in H2 and HD chemistry and cooling and their role in early structure formation
At low temperatures, the main coolant in primordial gas is molecular hydrogen, H 2 . Recent work has shown that primordial gas that is not collapsing gravitationally but is cooling from an initially
Formation of Population III stars in fossil H II regions : significance of HD
We study the evolution of gas in H II regions around the first stars after the exciting stars end their lives. If the first star in a small halo dies without supernova (SN), subsequent star formation
Affleck-Dine Baryogenesis and Heavy Element Production from Inhomogeneous Big Bang Nucleosynthesis
Recent observations have revealed that small-scale structure exists at high redshift. We study the possibility of the formation of such structure during baryogenesis and big bang nucleosynthesis. It
Primordial Nucleosynthesis in the Precision Cosmology Era
Primordial nucleosynthesis probes the Universe during its early evolution. Given the progress in exploring the constituents, structure, and recent evolution of the Universe, it is timely to review
