Observations made using large ground-based and space-borne telescopes have probed cosmic history from the present day to a time when the Universe was less than one-tenth of its present age. Earlier still lies the remaining frontier, where the first stars, galaxies and massive black holes formed. They fundamentally transformed the early Universe by endowing it with the first sources of light and chemical elements beyond the primordial hydrogen and helium produced in the Big Bang. The interplay…

The physics of early structure formation is focused on, while identifying several key issues and open questions, and prospects for future observations of the first stars, galaxies and blackholes are discussed.

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
Formation of the first stars in the universe
The standard cosmological model predicts that first cosmological objects are formed when the age of the universe is a few hundred million years. Recent theoretical works and numerical simulations

Abstract The formation of the first galaxies marks the end of the cosmic dark ages, initiating the prolonged process of reionization and enriching the pristine intergalactic medium with the first
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

Astronomers now have at their disposal telescopes and instruments that allow them to look back in time over most of the history of the Universe, from the present epoch to less than a billion years
Star Formation Within Nearby Galaxies
Galaxies, like the Milky Way in which we live, grow by merging with other galaxies and forming new stars. Star formation is fuelled by the cooling and collapse of clouds of gas, and this thesis aims
Formation of the First Galaxies: Theory and Simulations
The properties of the first galaxies are shaped in large part by the first generations of stars, which emit high energy radiation and unleash both large amounts of mechanical energy and the first
The earliest stars and their relics in the Milky Way
We have implemented a simple model to identify the likely sites of the first stars and galaxies in the high-resolution simulations of the formation of galactic dark matter haloes of the Aquarius

The First Stars
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
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.
The first stars in the universe.
Observations through telescopes reveal a much vaster realm that shines with the light from billions of galaxies that was featureless and dark for a long stretch of its early history.
Tracing the first stars with fluctuations of the cosmic infrared background
A measurement of diffuse flux fluctuations after removing foreground stars and galaxies, which exceed the instrument noise and the more local foregrounds and can be attributed to emission from population III stars, at an era dominated by these objects.
Protostar Formation in the Early Universe
An ab initio computer simulation of the formation of primordial stars that follows the relevant atomic and molecular processes in a primordial gas in an expanding universe shows that primeval density fluctuations left over from the Big Bang can drive the formation from a tiny protostar to a massive primordial star.
The Formation Of The First Stars In The Universe
In this review, I survey our current understanding of how the very first stars in the universe formed, with a focus on three main areas of interest: the formation of the first protogalaxies and the
The First Chemical Enrichment in the Universe and the Formation of Hyper Metal-Poor Stars
This work argues that these HMP stars are second-generation stars formed from gases that were chemically enriched by the first-generation supernovae, and can reproduce these abundance features with core-collapse “faint” supernova models that include extensive matter mixing and fallback during explosions.
The first generation of stars in the Λ cold dark matter cosmology
We have performed a large set of high-resolution cosmological simulations using smoothed particle hydrodynamics (SPH) to study the formation of the first luminous objects in the {Lambda}CDM
Dark Stars: Dark matter in the first stars leads to a new phase of stellar evolution
Abstract The first phase of stellar evolution in the history of the universe may be Dark Stars, powered by dark matter heating rather than by fusion. Weakly interacting massive particles, which are
The Formation of the First Star in the Universe
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.
