When galaxy formation started in the history of the Universe remains unclear. Studies of the cosmic microwave background indicate that the Universe, after initial cooling (following the Big Bang), was reheated and reionized by hot stars in newborn galaxies at a redshift in the range 6 < z < 14 (ref. 1). Though several candidate galaxies at redshift z > 7 have been identified photometrically, galaxies with spectroscopically confirmed redshifts have been confined to z < 6.6 (refs 4–8). Here we… 
Spectroscopic confirmation of a galaxy at redshift z = 8.6
TLDR
It is found that this single source is unlikely to provide enough photons to ionize the volume necessary for the emission line to escape, requiring a significant contribution from other, probably fainter galaxies nearby.
A galaxy rapidly forming stars 700 million years after the Big Bang at redshift 7.51
TLDR
A deep near-infrared spectroscopic survey of 43 photometrically-selected galaxies with z > 6.5 finds a surprisingly high star-formation rate of about 330 solar masses per year, which is more than a factor of 100 greater than that seen in the Milky Way.
A Rapidly Star-forming Galaxy 680 Million Years After the Big Bang at z=7.51
There are five spectroscopically confirmed z> 7 galaxies, all confirmed via Lymanα emission at z=7.008, 7.045, 7.109, 7.213 and 7.215. The small fraction of confirmed galaxies may indicate that the

Abstract Although the universe at redshifts greater than six represents only the first one billion years (< 10%) of cosmic time, the dense nature of the early universe led to vigorous galaxy

Abstract There has been great progress in recent years in discovering star forming galaxies at high redshifts (z > 5), close to the epoch of reionization of the intergalactic medium (IGM). The WFC3
Astronomy: Dawn after the dark age
The latest surveys provide evidence for one, maybe two, galaxies farther back in cosmic time than ever detected before. But does the fact that we don't see more mean these are the very first galaxies
Simulating high‐redshift galaxies
Recent observations have gathered a considerable sample of high-redshift galaxy candidates and determined the evolution of their luminosity function (LF). To interpret these findings, we use
Discovery of Lyman Break Galaxies at z ~ 7 from the zFourGE Survey
Star-forming galaxies at redshifts z > 6 are likely responsible for the reionization of the universe, and it is important to study the nature of these galaxies. We present three candidates for z ~ 7
A dusty, normal galaxy in the epoch of reionization
TLDR
Thermal dust emission from an archetypal early Universe star-forming galaxy, A1689-zD1, is reported, which has a large stellar mass and is heavily enriched in dust, with a dust-to-gas ratio close to that of the Milky Way.
LOW-METALLICITY STAR FORMATION IN HIGH-REDSHIFT GALAXIES AT z ∼ 8
Using the very deep near-infrared imaging of the Hubble Ultra Deep Field with WFC3 on the Hubble Space Telescope, five groups published the most probable samples of galaxies at z ∼ 8, selected by the

We report the discovery of a redshift z=6.56 galaxy lying behind the cluster Abell 370. The object HCM 6A was found in a narrowband imaging survey using a 118 Angstrom bandpass filter centered at

Luminosity functions of Lyman-α emitters at Redshift z=6.5 and z=5.7: Evidence against reionization at z ≈ 6
Lyman-α emission from galaxies should be suppressed completely or partially at redshifts beyond reionization. Without knowing the intrinsic properties of galaxies at z = 6.5 this attenuation is hard

We present the results of a survey for Lyα emitters at z ≈ 5.7 based on optical narrowband (λc = 8150 A and Δλ = 120 A) and broadband (B, R C, I C, and z') observations of the field surrounding the
Probing reionization with Lyman α emission lines
Lyman a emission from high-redshift galaxies may be a powerful probe of the ionization history of the intergalactic medium (IGM) at z > 6; the observed Lyman a emission line is sensitive to the IGM
Luminosity Functions of Lyα Emitters at Redshifts z = 6.5 and z = 5.7: Evidence against Reionization at z ≤ 6.5
The visibility of Lyα emission from galaxies should be suppressed substantially by a neutral intergalactic medium before reionization. Even after taking into account a local H II region produced by
