TL;DR: In this paper, the authors present a comprehensive study of the pulse profile and spectral evolution of two transient anomalous X-ray pulsars (TAXPs) XTE J1810-197 and CXOU J164710.2-455216.

TL;DR: The detection of variability from the proposed IR counterpart to the Anomalous X-ray Pulsar (AXP) 1E1048.1-5937 was reported in this article.

TL;DR: In this paper, the authors reported the discovery of the likely IR counterpart to the anomalous X-ray pulsar (AXP) 1RXS J170849-400910 based on the Chandra High Resolution Camera (imaging detector) X -ray position and the deep optical/IR observations carried out from ESO telescopes and the Canada-France-Hawaii Telescope during 1999-2002.

TL;DR: In this article, the authors reanalyze the Chandra spectra of Aql X-1, together with a long BeppoSAX observation in the same period, and propose a different interpretation of the spectral variability: that it is due to correlated variations of the power-law component and the column density (>5, a part of which might be intrinsic to the source), while the temperature and flux of the neutron star atmospheric component remain unchanged.

TL;DR: In this article, the authors analyzed high-resolution spectroscopic observations of the optical afterglow of GRB050730, obtained with UVES@VLT about hours after the GRB trigger.
