TL;DR: In this article, the authors detect the 158 −mu −m [CII] line from 12 galaxies at z~1-2 and show that the line is very luminous, between < 0.024-0.65% of the far-infrared continuum luminosity of the sources, and arises from PDRs on molecular cloud surfaces.

TL;DR: In this paper, the authors reported a 1 billion years after the Big Bang region of massive galaxies, which contains a luminous quasar as well as a system rich in molecular gas, and a lower limit of >4x10^11 solar masses of dark and luminous matter in this region consistent with that expected from cosmological simulations for the earliest galaxy clusters.

TL;DR: In this article, a new, representative spectroscopic sample of compact quiescent galaxies at z = 2 and a statistically well-understood sample of sub-millimeter selected galaxies (SMGs) were used to show that z=3-6 SMGs are consistent with being the progenitors of z=2 quiescents, matching their formation redshifts and their distributions of sizes, stellar masses and internal velocities.

TL;DR: The detection of 158 micron [CII] fine-structure line emission from MIPS J142824.0+352619, a hyperluminous (L_IR ~ 10^13 L_sun) starburst galaxy at z = 1.3, corresponds to a fraction of the far-IR (FIR) continuum as discussed by the authors.

TL;DR: The first extragalactic detection of the neutral carbon [CI] 3P2-3P1 fine structure line at 809 GHz was reported in this paper, where the line was observed towards M82 simultaneously with the 3P1 -3P0 line at 492 GHz, providing a precise measurement of the J=2-1/J=1-0 integrated line ratio of 0.96 (on a [K km s^-1] -scale).
