TL;DR: In this article, the CO ground-level transition in high-redshift quasi-stellar objects (QSOs) was detected using the NRAO Green Bank Telescope (GBT) and the MPIfR Effelsberg 100 m telescope.

TL;DR: In this paper, photometric redshifts from 17-band optical to mid-infrared photometry of 78 robust radio, 24-mu m and Spitzer IRAC counterparts to 72 of the 126 submillimetre galaxies (SMGs) selected at 870 mu m by LABOCA observations in the Extended Chandra Deep Field-South (ECDF-S).

TL;DR: In this article, a physically motivated IR spectral energy distribution-based approach is presented to account for possible contributions to 24 µm emission not associated with recent star formation, and the authors compare a large suite of SFR estimates and find that the intrinsic uncertainty in H{alpha-and FUV-based SFRs is approximately 0.3 and 0.5 dex.

TL;DR: In this article, the authors reported the detection of the 158 micron emission line and underlying dust continuum in the host galaxy of the quasar ULAS J112001.3 (hereafter J1120+0641) at z=7.7 arcsec^2.

TL;DR: In this paper, the authors reported the detection of high excitation CO emission from the most distant quasar currently known, SDSS J114816.64+525150.3, at a redshift z= 6:419.
