TL;DR: In this article, the Orion giant molecular cloud (GMC) was used as a local template for interpreting extra-galactic molecular line observations, and the authors used the wide-band receiver at the IRAM-30m to spatially and spectrally resolve the GMC.

TL;DR: The 8th Full Focal Plane Simulation Set (FFP8) as mentioned in this paper was deployed in support of the Planck 2015 results and consists of 10 fiducial mission realizations reduced to 18144 maps, together with the most massive suite of Monte Carlo realizations of instrument noise and CMB ever generated.

TL;DR: In this article, the integrated Sachs-Wolfe (ISW) effect from the Planck 2015 temperature and polarization data release is investigated from different perspectives, and the authors show that the ISW effect is detected only at ≈3σ, which is similar to the detection level achieved by combining the cross-correlation signal coming from all the galaxy catalogues mentioned above.

TL;DR: Generated at a cost of some 25 million CPU-hours spread across multiple high-performance-computing (HPC) platforms, FFP8 is used to validate and verify analysis algorithms and their implementations, and to remove biases from and quantify uncertainties in the results of analyses of the real data.

TL;DR: In this paper, the authors extended the DL dust model to simulate the optical extinction Av for the diffuse interstellar medium with optical estimates for 2 10^5 quasi-stellar objects (QSOs) observed in the Sloan digital sky survey and compared the DL Av estimates with those derived for molecular clouds from the near-IR colours of stars in the 2 micron all sky survey.
