TL;DR: The Swift mission as discussed by the authors is a multi-wavelength observatory for gamma-ray burst (GRB) astronomy, which is a first-of-its-kind autonomous rapid-slewing satellite for transient astronomy and pioneers the way for future rapid-reaction and multiwavelength missions.
Journal ArticleDOI
Femtosecond solvation dynamics of water
TL;DR: In this paper, the authors present experimental measurements of the ultrafast solvation dynamics of a coumarin salt in water, and combine them with computer simulations to demonstrate that a solvent response on a timescale faster than 50 fs can dominate aqueous solvation dynamic.

Properties of Relativistic Jets in Gamma-Ray Burst Afterglows
A. Panaitescu,Pawan Kumar +1 more
TL;DR: In this article, the authors extend the calculation of physical parameters of gamma-ray burst (GRB) jets by modeling the broadband emission of the afterglows of the GRB burst.
