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.

TL;DR: The Swift X-ray Telescope (XRT) as mentioned in this paper is designed to make astrometric, spectroscopic, and photometric observations of Xray emission from Gamma-ray Bursts and their afterglows in the energy band 0.2-10 keV.

TL;DR: In this article, the authors performed Monte Carlo simulations to derive the distribution of gamma-ray burst (GRB) polarizations in three emission models; the synchrotron model with a globally ordered magnetic field (SO model), the sychrotrae model with small-scale random magnetic fields (SR model), and the Compton drag model (CD model) to constrain the GRB emission models by using the statistical properties of GRB polarizations.

TL;DR: In this paper, the authors derived an empirical timelag redshift from the BAT data of (z) over bar z 0: 69 +/- 0: 02, in good agreement with the spectroscopic redshift of 0.61.

TL;DR: The micropattern time projection chamber (TPC) offers a novel method of imaging the tracks of photoelectrons as a means of X-ray polarimetry with the potential to simultaneously achieve large modulation factors and high quantum efficiency as discussed by the authors.
