TL;DR: Arcus, a Medium Explorer (MIDEX) mission, was selected by NASA for a Phase A study in August 2017 as mentioned in this paper, which provides high-resolution soft X-ray spectroscopy in the 12-50A bandpass with unprecedented sensitivity: effective areas of >450 cm^2 and spectral resolution >2500.

TL;DR: In this paper, Hitomi observations of N132D, a young, X-ray bright, O-rich core-collapse supernova remnant in the Large Magellanic Cloud (LMC), were used to detect the line complexes of highly ionized S K and Fe K with 16-17 counts.

TL;DR: Dauser et al. as discussed by the authors presented an extended scheme for the calculation of the profiles of emission lines from accretion disks around rotating black holes, including disks with angular momenta which are parallel and antiparallel with respect to the black hole's angular momentum, as both configurations are assumed to be stable.

TL;DR: The Spectroscopic Time-Resolving Observatory for Broadband Energy X-rays (STROBE-X) as discussed by the authors is a probe-class mission concept that provides an unprecedented view of the X-ray sky, performing timing and spectroscopy over both a broad energy band (0.2-30 keV) and a wide range of timescales from microseconds to years.

TL;DR: Arcus provides high-resolution soft X-ray spectroscopy in the 12-50 A bandpass with unprecedented sensitivity, including spectral resolution < 2500 and effective area < 250 cm2 as mentioned in this paper.
