TL;DR: The Advanced Telescope for High Energy Astrophysics (Athena+) mission as discussed by the authors provides the necessary performance (e.g., angular resolution, spectral resolution, survey grasp) to address these questions and revolutionize our understanding of the Hot and Energetic Universe.

TL;DR: The X-ray Imaging Polarimetry Explorer (XIPE) as discussed by the authors is a mission dedicated to Xray Astronomy which is in a competitive phase A as fourth medium size mission of ESA (M4).

TL;DR: The core scientific objectives of Athena are reviewed, driving the main performance parameters of the X-IFU, namely the spectral resolution, the field of view, the effective area, the count rate capabilities, the instrumental background and the breakthrough potential.

TL;DR: The X-ray Integral Field Unit (X-IFU) on board the Advanced Telescope for High-ENergy Astrophysics (Athena) will provide spatially resolved high-resolution Xray spectroscopy from 0.2 to 12 keV, with 5 arc second pixels over a field of view of 5 arc minute equivalent diameter and a spectral resolution of 2.5 eV up to 7 keV as mentioned in this paper.

TL;DR: The X-ray Imaging Polarimetry Explorer (XIPE) as mentioned in this paper was proposed in 2012 to the first ESA call for a small mission with a launch in 2017, but the proposal was, unfortunately, not selected.
