متن کاملCollimated Jet or Expanding Outflow: Possible Origins of GRBs and X-Ray Flashes
We investigate the dynamics of an injected outflow propagating in a progenitor in the context of the collapsar model for gamma-ray bursts (GRBs) through two dimensional axisymmetric relativistic hydrodynamic simulations. Initially, we locally inject an outflow near the center of a progenitor. We calculate 25 models, in total, by fixing its total input energy to be 10ergs s and radius of the inj...
متن کاملThe Soft X-ray Background and Origins Its
The sky in the soft X-ray region of the electromagnetic spectrum (photon energies between roughly 0.1 and 10 keV) is far from dark: Over this entire energy range, the diffuse flux is much greater than the contribution from identifiable discrete sources. It now appears that there are several diffuse X-ray backgrounds, and despite the title of this review, we are not all that sure of the origin o...
