TL;DR: This paper showed that NGC5907 ULX is instead an x-ray accreting neutron star (NS) with a spin period evolving from 1.43~s in 2003 to 1.13 ~s in 2014.

TL;DR: Ultraviolet and x-ray observations of a binary neutron star merger show a hot kilonova but no jet along the line of sight, which avoids both obscuration from the heaviest elements in the orbital plane and a direct view of any ultrarelativistic, highly collimated ejecta.

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: In this article, the sky localization of the first observed compact binary merger is presented, where the authors describe the low-latency analysis of the LIGO data and present a sky localization map.

TL;DR: In this article, the early phases of the X-ray emission of five long-lived γ-ray bursts were studied using the Swift satellite, and it was shown that violent shock interactions take place in the early jet outflows, leading to a rapid falloff for the first few hundred seconds followed by a less rapid decline lasting several hours.
