Revisiting GRB 060218: new insights into low-luminosity gamma-ray bursts from a revised shock breakout model
Christopher M. Irwin, Kenta Hotokezaka
Despite two decades since the discovery of low-luminosity gamma-ray bursts, their origin remains poorly understood. In events such as GRB 060218, shock breakout from a progenitor w…
Demystifying shock breakout spectra
Christopher M. Irwin, Kenta Hotokezaka
The spectrum of the first supernova light (i.e., the shock breakout and early cooling emission) is an important diagnostic for the state of the progenitor star just before explosio…
An unexplored regime of shock breakout with a distinct spectral signature
Christopher M. Irwin, Kenta Hotokezaka
The first light that escapes from a supernova explosion is the shock breakout emission, which produces a bright flash of UV or X-ray radiation. Standard theory predicts that the sh…
Dynamical properties of mildly relativistic ejecta produced by the mass-loading of gamma-ray burst jets in dense ambient media
Akihiro Suzuki, Christopher M. Irwin, Keiichi Maeda
We present the results of a series of 3D special relativistic hydrodynamic simulations of a gamma-ray burst (GRB) jet in a massive circumstellar medium (CSM) surrounding the progen…
