TL;DR: The Photodetector Array Camera and Spectrometer (PACS) as discussed by the authors is one of the three science instruments on ESA's far infrared and sub-mil- limetre observatory.

TL;DR: Euclid as mentioned in this paper is a space-based survey mission from the European Space Agency designed to understand the origin of the universe's accelerating expansion, using cosmological probes to investigate the nature of dark energy, dark matter and gravity by tracking their observational signatures.

TL;DR: In this article, the authors report on the production of a large area, shallow, sky survey, from XMM-Newton slews, in three distinct energy bands; a soft (0.2 −2 keV) band, a hard (2 −12 keV)-band and a total XMMNewton band (0 −12 −3 keV).

TL;DR: The XXL-XMM survey as discussed by the authors provides constraints on the dark energy equation of state from the space-time distribution of clusters of galaxies and serves as a pathfinder for future, wide-area X-ray missions.
