Abstract The formation of the first generations of stars at redshifts z ≥ 15 − 20 signaled the transition from the simple initial state of the universe to one of ever increasing complexity. We here review recent progress in understanding the assembly process of the first galaxies, starting with cosmological initial conditions and modelling the detailed physics of star formation. In particular, we study the role of HD cooling in ionized primordial gas, the impact of UV radiation produced by the…

Abstract One of the key challenges for the next 10 years is to understand the first sources of light, the first stars and possibly accreting black holes. Their formation ended the cosmic dark ages at

The First Galaxies

Abstract An important open frontier in astrophysics is to understand how the first sources of light, the first stars and galaxies, ended the cosmic dark ages at redshifts z ≃ 15 − 20. Their formation

The formation of the first galaxies and the transition to low-mass star formation

Abstract The formation of the first galaxies at redshifts z ~ 10−15 signaled the transition from the simple initial state of the universe to one of ever increasing complexity. We here review recent

Pregalactic metal enrichment: The chemical signatures of the first stars

The emergence of the first sources of light at redshifts of $z\ensuremath{\sim}10--30$ signaled the transition from the simple initial state of the Universe to one of increasing complexity. Recent

Predictions for the upcoming James Webb space telescope (JWST), to be launched ~2018, and for 'stellar archaeology', which probes the abundance pattern in the oldest, most-metal poor stars in the authors' cosmic neighborhood, thereby constraining the nucleosynthesis inside the first supernovae are discussed.

Star Formation for Predictive Primordial Galaxy Formation

The elegance of inflationary cosmology and cosmological perturbation theory ends with the formation of the first stars and galaxies, the initial sources of light that launched the phenomenologically

The first galaxies: signatures of the initial starburst

Detection of the radiation emitted from the first galaxies at z ≥ 10 will be made possible in the next decade, with the launch of the James Webb Space Telescope (JWST). We carry out cosmological

Formation of the First Stars and Black Holes

We review the current status of knowledge concerning the early phases of star formation during cosmic dawn. This includes the first generations of stars forming in the lowest mass dark matter halos

The Reionization of the Universe by the First Stars and Quasars

▪ Abstract The formation of the first stars and quasars marks the transformation of the universe from its smooth initial state to its clumpy current state. In popular cosmological models, the first

The Formation of the First Globular Clusters in Dwarf Galaxies before the Epoch of Reionization

We explore a mechanism for the formation of the first globular clusters, operating during the assembly of dwarf galaxies at high redshifts, z ≳ 10. The substructure in the dark matter and the

The characteristic stellar mass as a function of redshift

We present a model for the star formation process during the initial collapse of dark matter haloes at redshifts z = 0-30. We derive a simple formula for the characteristic stellar mass scale during

The Formation of the First Stars. I. The Primordial Star-forming Cloud

To constrain the nature of the very first stars, we investigate the collapse and fragmentation of primordial, metal-free gas clouds. We explore the physics of primordial star formation by means of

Cosmological origin of the lowest metallicity halo stars

We explore the predictions of the standard hierarchical clustering scenario, regarding the numbers and metallicities of PopIII stars found within our Galaxy today. An analytic, extended

The H II Region of the First Star

Simulations predict that the first stars in a ΛCDM universe formed at redshifts z > 20 in minihalos with masses of about 106 M☉. We have studied their radiative feedback by simulating the propagation

Three Epochs of Star Formation in the High-Redshift Universe

We investigate the impact of an early population of massive stars on their surroundings. Dissociation of molecular hydrogen by strong UV emission from such stars is expected to produce a global

The Era of Massive Population III Stars: Cosmological Implications and Self-Termination

The birth and death of the first generation of stars have important implications for the thermal state and chemical properties of the intergalactic medium (IGM) in the early universe. Sometime after

Cosmological Effects of the First Stars: Evolving Spectra of Population III

The first stars hold intrinsic interest for their uniqueness and for their potentially important contributions to galaxy formation, chemical enrichment, and feedback on the intergalactic medium

The Dark Age of the Universe

The Cold Dark Matter theory for structure formation predicts that the first sources formed much earlier, and the most distant sources of light known at present are galaxies and quasars at redshift z ≅ 6, and their spectra indicate that the end of reionization was occurring just at that time.
