We provide a comprehensive review of major developments in our understanding of gamma-
ray bursts, with particular focus on the discoveries made within the last fifteen years when …

Over half a century from the discovery of gamma-ray bursts (GRBs), the dominant radiation
mechanism responsible for their bright and highly variable prompt emission remains poorly …

The merger of two dense stellar remnants including at least one neutron star is predicted to
produce gravitational waves (GWs) and short-duration gamma ray bursts,. In the process …

ABSTRACT GRB 130427A was extremely bright as a result of occurring at low redshift whilst
the energetics were more typical of high-redshift gamma-ray bursts (GRBs). We collected …

We present the first reported case of the simultaneous metallicity determination of a gamma-
ray burst (GRB) host galaxy, from both afterglow absorption lines as well as strong emission …

Using the three-dimensional relativistic magnetohydrodynamic code RAISHIN, we
investigated the influence of the radial density profile on the spatial development of the …

Context. Long gamma-ray bursts (GRBs) are produced by the collapse of some very
massive stars, that emit ultra-relativistic jets. When the jets collide with the interstellar …

We theoretically verify that optical vortices carrying orbital angular momentum are generated
in various astrophysical situations via nonlinear inverse Thomson scattering. Arbitrary angle …

Synchrotron emission from astrophysical nonthermal sources usually assumes that the
emitting particles are isotropic. By means of large-scale two-and three-dimensional particle …

We study the evolution of photon polarization during the photon-axion conversion process
with focusing on the magnetic field configuration dependence. Most previous studies have …
