TL;DR: In this paper, the authors explore photospheric emissions from stratified two-component jets, where a highly relativistic spine outflow is surrounded by a wider and less sensitive sheath outflow, and they show that the high energy part of observed gamma-ray bursts (GRBs) photon spectrum can be explained by this photon acceleration mechanism.

TL;DR: In this article, the spectral and polarization properties of photospheric emissions from stratified jets were explored. And the authors found that the presence of the lateral structure within the jet leads to the nonthermal feature of the spectra and significant polarization signal in the resulting emission, and that deviation from thermal spectra, as well as the polarization degree, tends to be enhanced as the velocity gradient in the shear region increases.

TL;DR: In this article, two-dimensional axisymmetric hydrodynamic simulations of matter mixing in aspherical core-collapse supernova explosions of a 16.3 M star with a compact hydrogen envelope were performed.
