TL;DR: In this paper, a piece-wise linear spline function was used to modify the vignetting response of the Crab as the primary effective area calibrator, and the achieved residuals for all off-axis angles and energies, compared to the assumed spectrum, are typically better than 2$\% up to 40\,keV and 5--10\,\% above due to limited counting statistics.

TL;DR: The Hubble Deep Field provides one of the deepest multiwavelength views of the distant Universe and has led to the detection of thousands of galaxies seen throughout cosmic time, with a redshift significantly higher than earlier estimates and higher than those of most of the hundreds of submillimetre-bright galaxies identified so far.

TL;DR: In this article, coherent pulsations from the ultraluminous X-ray source (ULX) NGC 7793 P13 were detected using XMM-Newton and NuSTAR data.

TL;DR: In this article, a set of low-resolution empirical SED templates for AGNs and galaxies in the wavelength range from 0.03 to 30 microns based on the multi-wavelength photometric observations of the NOAO Deep-Wide Field Survey Bootes field and the spectroscopic observations of AGN and Galaxy Evolution Survey is presented.

TL;DR: In this paper, the Leibniz Prize (DFG) was used for the first time to evaluate the performance of the NSF Telescope System Instrumentation Program (TSIP).
