TL;DR: In this paper, the authors investigate whether there is any correlation between the X-ray afterglow luminosity and the prompt emission properties of a carefully selected sub-sample of bright Swift long Gamma-Ray Bursts nearly complete in redshift (� 90%).

TL;DR: In this paper, the afterglow X-ray emission was monitored by the XRT up to 28 days after the GRB burst and the light curve showed a decay with three different phases, each characterized by a distinct slope: an initial steep decay with a power law index of ~ 5.5, a second phase characterised by a flat decay slope of \~ 0.54, and a third phase with a decaying slope of ~ 1.14.

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.

TL;DR: In this paper, the authors summarize past electromagnetic follow-up efforts as well as the organization and policy of the current EM followup program and compare the four probability sky maps produced for the gravitational-wave transient GW150914, and provide additional details of the EM follow up observations that were performed in the different bands.

TL;DR: In this article, the authors report the results of the analysis of the Swift X-ray Telescope Point Spread Function (PSF) as measured in the first four months of the mission during the instrument calibration phase.
