TL;DR: In this paper, a z = 2.12 submillimeter galaxy, ALESS67.1, was studied using sub-arcsecond resolution ALMA, adaptive optics-aided VLT/SINFONI, and Hubble Space Telescope (HST)/CANDELS data to investigate the kinematics and spatial distributions of dust emission (870?m continuum), 12CO(J = 3-2), strong optical emission lines, and visible stars.

TL;DR: In this paper, the shape of the CO luminosity function at high redshift was measured using the NSF's Karl G. Jansky Very Large Array (VLA) observations.

TL;DR: In this article, the authors investigate the relationship between spiral arms and star formation in the grand-design spirals NGC 5194 and NGC 628 and in the flocculent spiral NGC 6946.

TL;DR: In this article, a large Gemini program was used to observe z>~5.7 quasars with GNIRS near-IR spectroscopy, and the results showed that these high-z quaars have similar continuum and emission line properties and occupy the same region in the black hole mass and luminosity space as the comparison sample, accreting at an average Eddington ratio of ~0.3.

TL;DR: In this article, the authors reported new observations of CO (2-1) line emission toward five z ~ 6 quasars using the Ka-band receiver system on the Expanded Very Large Array (EVLA).
