TL;DR: The Swift mission as discussed by the authors is a multi-wavelength observatory for gamma-ray burst (GRB) astronomy, which is a first-of-its-kind autonomous rapid-slewing satellite for transient astronomy and pioneers the way for future rapid-reaction and multiwavelength missions.

TL;DR: In particular in the 5-10 keV band these observations present the deepest X-ray survey ever, about a factor 20 more sensitive than the previous BeppoSAX observations.

TL;DR: The first deep X-ray survey with the XMM-Newton observatory during the performance verification phase was reported in this article, where the European Photon Imaging Camera (EPIC) detectors reached a flux limit of 0.31, 1.4, and 2.4 X 10−15−15 cm−2 s−1, respectively in the 0.5-2, 2-10, and 5-10 keV bands.

M. Arnaud,Nabila Aghanim,R. Gastaud,Doris M. Neumann,David H. Lumb,Ulrich G. Briel,Bruno Altieri,Simona Ghizzardi,Jonathan P. D. Mittaz,T. P. Sasseen,W. T. Vestrand +10 more
TL;DR: In this article, a temperature map and a temperature profile of the central part (r < 20' or 1/4 virial radius) of the Coma cluster were presented, where five overlapping pointings made with XMM/EPIC/MOS and extracted spectra were combined.

Ulrich G. Briel,J. Patrick Henry,David H. Lumb,M. Arnaud,Doris M. Neumann,Nabila Aghanim,Rene Gastaud,Jonathan P. D. Mittaz,T. P. Sasseen,W. Tom Vestrand +9 more
TL;DR: The Coma cluster of galaxies was observed with XMM-Newton in 12 partially overlapping pointings as mentioned in this paper, and the resulting X-ray map in different energy bands and discuss the large scale structure of this cluster.
