‘Jet breaks’ and ‘missing breaks’ in the X-Ray afterglow of Gamma Ray Bursts
The X-ray afterglows (AGs) of Gamma-Ray Bursts (GRBs) and X-Ray Flashes (XRFs) have, after the fast decline phase of their prompt emission, a temporal behaviour varying between two extremes. A large fraction of these AGs has a ‘canonical’ light curve which, after an initial shallow-decay ‘plateau’ phase, ‘breaks smoothly’ into a fast power-law decline. Very energetic GRBs, contrariwise, appear ...
متن کاملJet Breaks in Short Gamma-ray Bursts. Ii. the Collimated Afterglow of Grb 051221a
We report the best evidence to date of a jet break in a short gamma-ray burst (GRB) afterglow, using Chandra and Swift XRT observations of the X-ray afterglow of GRB 051221A. The combined X-ray light curve, which has three breaks, is similar to those commonly observed in Swift observations of long GRBs. A flat segment of the light curve at 0.1 days after the burst represents the first clear cas...
متن کاملJet Breaks in Short Gamma-ray Bursts. I: the Uncollimated Afterglow of Grb050724
We report the results of the Chandra observations of the Swift-discovered short Gamma-Ray Burst GRB050724. Chandra observed this burst twice, about two days after the burst and a second time three weeks later. The first Chandra pointing occurred at the end of a strong late-time flare. About 150 photons were detected during this 49.3 ks observation in the 0.4-10.0 keV range. The spectral fit is ...
متن کاملSimulations of Grb Jets in a Stratified External Medium: Dynamics, Afterglow Lightcurves, Jet Breaks and Radio Calorimetry
The dynamics of gamma-ray burst (GRB) jets during the afterglow phase is most reliably and accurately modeled using hydrodynamic simulations. All published simulations so far, however, have considered only a uniform external medium, while a stratified external medium is expected around long duration GRB progenitors. Here we present simulations of the dynamics of GRB jets and the resulting after...
متن کاملWhen it breaks , it breaks
Dependencies among software projects and libraries are an indicator of the often implicit collaboration among many developers in software ecosystems. Negotiating change can be tricky: changes to one module may cause ripple effects to many other modules that depend on it, yet insisting on only backwardcompatible changes may incur significant opportunity cost and stifle change. We argue that awar...
