Candidates for the modest galaxies that formed most of the stars in the early Universe, at redshifts z > 7, have been found in large numbers with extremely deep restframe-ultraviolet imaging. But it has proved difficult for existing spectrographs to characterize them using their ultraviolet light. The detailed properties of these galaxies could be measured from dust and cool gas emission at far-infrared wavelengths if the galaxies have become sufficiently enriched in dust and metals. So far… 
Normal, dust-obscured galaxies in the epoch of reionization.
TLDR
It is concluded that the contribution of dust-obscured galaxies to the cosmic star formation rate density at z’s greater than 6 is sub-dominant and this population of heavily dust-OBscuring galaxies appears to contribute 10-25% to the z > 6 cosmic starformation rate density.
Dust-obscured star-forming galaxies in the early universe
Motivated by recent observational constraints on dust reprocessed emission in star-forming galaxies at z ∼ 6 and above, we use the very large cosmological hydrodynamical simulation BLUETIDES to
Detection of an oxygen emission line from a high-redshift galaxy in the reionization epoch
TLDR
The Atacama Large Millimeter/submillimeter Array detection of an oxygen emission line at a wavelength of 88 micrometers from a galaxy at an epoch about 700 million years after the Big Bang is reported.
The assembly of dusty galaxies at z ≥ 4: statistical properties
The recent discovery of high-redshift dusty galaxies implies a rapid dust enrichment of their interstellar medium (ISM). To interpret these observations, we run a cosmological simulation in a 30
Galaxies at redshifts 5 to 6 with systematically low dust content and high [C ii] emission
TLDR
It is found that nine typical star-forming galaxies about one billion years after the Big Bang have thermal emission that is less than 1/12 that of similar systems about two billion years later, and enhanced [C ii] emission relative to the far-infrared continuum, confirming a strong evolution in the properties of the interstellar medium in the early Universe.
The dust mass in z > 6 normal star-forming galaxies
We interpret recent ALMA observations of z > 6 normal star forming galaxies by means of a semi-numerical method, which couples the output of a cosmological hydrodynamical simulation with a chemical
Dust evolution processes in normal galaxies at z > 6 detected by ALMA
Recent ALMA observations of high-redshift normal galaxies have been providing a great opportunity to clarify the general origin of dust in the Universe, not biased to very bright special objects even
Star formation and the interstellar medium in z>6 UV-luminous Lyman-break galaxies
We present Atacama Large Millimeter Array (ALMA) detections of atomic carbon line and dust continuum emission in two UV-luminous galaxies at redshift 6. The far-infrared (FIR) luminosities of these
A dusty star-forming galaxy at z = 6 revealed by strong gravitational lensing
Since their discovery, submillimetre-selected galaxies1,2 have revolutionized the field of galaxy formation and evolution. From the hundreds of square degrees mapped at submillimetre wavelengths3–5,
AN INCREASING STELLAR BARYON FRACTION IN BRIGHT GALAXIES AT HIGH REDSHIFT
Recent observations have shown that the characteristic luminosity of the rest-frame ultraviolet (UV) luminosity function does not significantly evolve at 4 < z < 7 and is approximately M UV ∼ −21. We

Cool Gas in High-Redshift Galaxies
Over the past decade, observations of the cool interstellar medium (ISM) in distant galaxies via molecular and atomic fine structure line (FSL) emission have gone from a curious look into a few
A dust-obscured massive maximum-starburst galaxy at a redshift of 6.34
TLDR
Despite the overall downturn in cosmic star formation towards the highest redshifts, it seems that environments mature enough to form the most massive, intense starbursts existed at least as early as 880 million years after the Big Bang.
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.
The rarity of dust in metal-poor galaxies
TLDR
Observations of dust emission from I’Zw’18 are reported, from which it is determined its dust mass to be 450–1,800 solar masses, yielding a dust-to-stellar mass ratio of about 10−6 to 10−5 and a Dust-To-gasmass ratio of 3.2–13 × 10−6.
Cosmic evolution of submillimeter galaxies and their contribution to stellar mass assembly
The nature of galaxies selected at submillimeter wavelengths (SMGs, S 850 ≳ 3 mJy), some of the bolometrically most luminous objects at high redshifts, is still elusive. In particular their star
Dust Masses, PAH Abundances, and Starlight Intensities in the SINGS Galaxy Sample
Physical dust models are presented for 65 galaxies in SINGS that are strongly detected in the four IRAC bands and three MIPS bands. For each galaxy we estimate (1) the total dust mass, (2) the

We present a simple, largely empirical but physically motivated model to interpret the mid- and far-infrared spectral energy distributions of galaxies consistently with the emission at ultraviolet,
A galaxy at a redshift z = 6.96
TLDR
A spectroscopic redshift of z = 6.96 is reported for a galaxy whose spectrum clearly shows Lyman-α emission at 9,682 Å, indicating active star formation at a rate of ∼10M[circdot] yr-1, which demonstrates that galaxy formation was under way when the Universe was only ∼6 per cent of its present age.

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
