TL;DR: In this paper, the authors used VLT optical/NIR images coupled with Swift X-ray positioning, and optical spectra of the host galaxy to measure its properties, and found a single galaxy within the error box of GRB 050223.

TL;DR: In this article, the cosmological background of gravitational waves produced by magnetars is derived based on a numerical model of the cosmic star formation history, and the strongest signals are generated for magnetars with very intense toroidal internal fields (∼10 16 G range) and external dipole fields of ∼10 14, as envisaged in models aimed at explaining the properties of the 2004 December giant flare from SGR 1806-20.

TL;DR: In this article, a comprehensive analysis of all the available XMM-Newton observations of SGR 0526-66 is presented, thanks to a deep observation taken in 2007, which measured its pulsation period (P = 8.0544 +/- 0.0002 s) 6 years after its latest detection by Chandra.

TL;DR: In this paper, the authors detected two large spin glitches ( ∆ν ν of 1.2 and 2.1 × 10 −6 ) that occurred in January and June 2005.

TL;DR: In this paper, a phase-connected timing analysis extending back to the ROSAT data obtained in 1992 was performed on the hot subdwarf HD 49798, which has an X-ray emitting compact companion with a spin period of 13.2 s and a dynamically measured mass of 1.28+/- 0.05 M_sun.
