Galaxies at redshifts 5 to 6 with systematically low dust content and high [C ii] emission
Volume 10, Issue 26 - article #8
Measurements of [C ii] emission
and
dust emission from nine typical star-forming galaxies about one billion years after the Big Bang show that galaxies of this age have dust levels that are significantly lower than those of typical galaxies about two billion years later
and
comparable with those of local low-metallicity galaxies.

The Laniakea supercluster of galaxies
Volume 9, Issue 22 - article #73
Examination of a three-dimensional map of galaxies
and
their velocities shows a surface bounding the motions of galaxies that are inward after removal of the mean cosmic expansion
and
long-range flows
,
the galaxies within this surface lie within our home supercluster.

A single low-energy, iron-poor supernova as the source of metals in the star SMSS J031300.36−670839.3
Volume 9, Issue 9 - article #15
The optical spectrum of the star SMSS J031300.36−670839.3 shows no evidence of iron
,
this
,
together with comparisons of the star’s observed element abundance pattern with those of models
,
means that SMSS J031300.36−670839.3 must have been seeded with material from a single supernova with an original mass about 60 times that of the Sun.

Extremely metal-poor gas at a redshift of 7
Volume 7, Issue 49 - article #18
The spectrum of a quasar at redshift 7.04 reveals absorption from a large column of foreground neutral hydrogen with no corresponding heavy elements
,
this absorbing gas is either diffuse
and
intergalactic but has not yet been ionized by starlight at this early epoch
,
or it is gravitationally bound to a proto-galaxy that has a chemical abundance <1/10,000
,
the solar level.
