During the roughly 20 seconds it shines brightest, a gamma-ray burst (GRB) is over a billion times brighter, in electromagnetic radiation, than an ordinary supernova. The key difference is that GRBs emit some appreciable fraction of their kinetic ene

Cosmic gamma-ray bursts now appropriately hold the distinction of being the “largest explosions in the universe”. Their afterglows are often brighter than supernovae, thus often referred to as “hypernovae”. Their kinetic energies may also be

Numerical jet simulations serve a valuable role in calculating gamma-ray burst afterglow emission beyond analytical approximations. Here we present the results of high resolution 2D simulations of decelerating relativistic jets performed using the RA

Gamma‐ray bursts are ultra‐relativistic explosions resulting in some cases from the death of massive stars. Numerical modeling of these explosions is challenging because of the extreme Lorentz factors (Γ≳100) and the range of length scales enc

The fate of massive (Mms≳25 M⊙) rotating stars for which the Type-II supernova mechanism fails to launch a strong explosion is studied by means of 1D and 2D hydrodynamical simulations. In the extreme case (Mms≳35 M⊙) a collapsar-a rapidly acc

GRBs have redshifts comparable to, perhaps even larger than those of quasars. Indeed, they are the most energetic explosions in the universe, with energies of order M⊙c2. Their host galaxies are faint, but are actively forming stars at rates typica
