TL;DR: Optical and near-infrared observations of the afterglow of the gamma-ray burst GRB 050904 show that the detection is consistent with the expected number of GRBs at z > 6 and shows that GRBs are a powerful tool to study the star formation history up to very high redshift.

TL;DR: In this article, the authors presented the discovery of SGR J1745-29 by Swift, including analysis of data before, during, and after the burst, and found that the spectrum in the 0.3-10 keV range is well fit by an absorbed blackbody model with kTBB ~ 1 keV and absorption consistent with previously measured values from the quiescent emission from Sgr A*, strongly suggesting that this source is at a similar distance.

TL;DR: In this article, the authors report the results of the Swift and XMM-Newton observations of the discovered GRB 060729 (T90 = 115 s) and show that the afterglow of this burst was exceptionally bright in X-rays as well as at UV/optical wavelengths, showing an unusually long slow decay phase (? = 0.14? 0.02), suggesting a larger energy injection phase at early times than in other bursts.

TL;DR: In this article, the authors present soft X-ray, N(H) and IR maps of the Eridanus soft Xray enhancement, which shows that the enhancement consists of two distinct components: a large hook-shaped component and a small circular component at different temperatures.

TL;DR: In this article, high-resolution Chandra observations of the remnant of SN1987A in the Large Magellanic Cloud (LMC) have been presented, showing that the X-ray emission is thermal in origin and dominated by highly ionized species of O, Ne, Mg, and Si.
