Large telescopes have allowed astronomers to observe galaxies that formed as early as 850 million years after the big bang. We predict when the first star that astronomers can observe (i.e. in our past light cone) formed in the Universe, accounting for the first time for the size of the Universe and for three essential ingredients: the light travel-time from distant galaxies, Poisson and density fluctuations on all scales, and the effect of very early cosmic history on galaxy formation. We find…

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…

Detecting early galaxies through their 21‐cm signature
New observations over the next few years of the emission of distant objects will help unfold the chapter in cosmic history around the era of the first galaxies. These observations will use the…
The numerical frontier of the high-redshift Universe
The first stars are believed to have formed a few hundred million years after the big bang in so-called dark matter minihalos with masses ∼106 M⊙$\sim 10^{6}\mbox{ M}_{\odot}$. Their radiation lit up…
The signature of the first stars in atomic hydrogen at redshift 20
TLDR
A simulation of the distribution of the first stars at redshift 20 is reported, finding that the 21-centimetre hydrogen signature of these stars is an enhanced fluctuation signal on the hundred-megaparsec scale, characterized by a flat power spectrum with prominent baryon acoustic oscillations.
THE FIRST GALAXIES: ASSEMBLY OF DISKS AND PROSPECTS FOR DIRECT DETECTION
The James Webb Space Telescope (JWST) will enable observations of galaxies at redshifts z {approx}> 10 and hence allow us to test our current understanding of structure formation at very early times.…

TLDR
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.
On the Habitability of Our Universe
Is life most likely to emerge at the present cosmic time near a star like the Sun? We consider the habitability of the Universe throughout cosmic history, and conservatively restrict our attention to…

Simulations of the formation, evolution and clustering of galaxies and quasars
TLDR
It is shown that baryon-induced features in the initial conditions of the Universe are reflected in distorted form in the low-redshift galaxy distribution, an effect that can be used to constrain the nature of dark energy with future generations of observational surveys of galaxies.
The history of star formation in a lcdm universe
Employing hydrodynamic simulations of structure formation in a ⁄CDM cosmology, we study the history of cosmic star formation from the \dark ages" at redshift z » 20 to the present. In addition to…
The Dark Age of the Universe
TLDR
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.
UNUSUALLY LARGE FLUCTUATIONS IN THE STATISTICS OF GALAXY FORMATION AT HIGH REDSHIFT
We show that various milestones of high-redshift galaxy formation, such as the formation of the first stars or the complete reionization of the intergalactic medium, occurred at different times in…
THE NUMBER OF SUPERNOVAE FROM PRIMORDIAL STARS IN THE UNIVERSE
We explore the consequences of radiative feedback on early generations of star formation. The main cooling mechanism in primordial star formation is from rotational line emission of molecular…
Growth of Linear Perturbations before the Era of the First Galaxies
We calculate the evolution of linear density and temperature perturbations in a universe with dark matter, baryons and radiation, from cosmic recombination until the epoch of the first galaxies. In…
The first generation of star-forming haloes
We model gas cooling in high-resolution N-body simulations in order to investigate the formation of the first generation of stars. We follow a region of a Lambda cold dark matter (�CDM) universe…
The Formation of the First Star in the Universe
TLDR
It is concluded that at most one massive metal-free star forms per pregalactic halo, consistent with recent abundance measurements of metal-poor galactic halo stars.
