TLDR
In this paper, a fluid dynamical treatment of an ultra-relativistic spherical blast wave enclosed by a strong shock is presented, and a simple similarity solution describing the explosion of a fixed amount of energy in a uniform medium is derived, and generalized to include cases in which power is supplied by a central source and the density of the external medium varies with radius.Abstract:
A fluid dynamical treatment of an ultra‐relativistic spherical blast wave enclosed by a strong shock is presented. A simple similarity solution describing the explosion of a fixed amount of energy in a uniform medium is derived, and this is generalized to include cases in which power is supplied by a central source and the density of the external medium varies with radius. Radiative shocks, in which the escaping photons carry away momentum as well as energy, are also discussed. Formulas that interpolate between the non‐ and ultra‐relativistic limits are proposed.read more

High Energy Neutrinos from Gamma-Ray Bursts
TL;DR: A review of recent work on the production of high-energy neutrinos by GRB fireballs is presented in this article, showing that a significant fraction of GRB energy is expected to be converted to an accompanying burst of high energy neutrino, and that the detection of such events correlated with GRBs will allow to constrain GRB progenitor models and test the suggestion that GRBs accelerate protons to >10^20 eV.

Self-similar imploding relativistic shock waves
J. C. Hidalgo,S. Mendoza +1 more
TL;DR: In this article, self-similar solutions to the problem of a strong imploding relativistic shock wave are calculated, assuming that the preshocked flow has a uniform density and are accurate for sufficiently large times after the formation of the shock wave.

The newborn black hole in GRB 191014C proves that it is alive
TL;DR: In this article, an efficient general relativistic electrodynamical process which occurs in the "inner engine" of a binary driven hypernova was shown. But the inner engine is composed of a rotating Kerr BH of mass M and dimensionless spin parameter α, a magnetic field of strength B 0 aligned and parallel to the rotation axis, and a very low-density ionized plasma.

The Location and Environments of Neutron Star Mergers in an Evolving Universe
Brandon K. Wiggins,Brandon K. Wiggins,Chris L. Fryer,Joseph Smidt,Dieter H. Hartmann,Nicole M. Lloyd-Ronning,Chris Belcynski +6 more
TL;DR: In this paper, the authors present cosmological simulations following the evolution of a galaxy cluster including star formation combined with binary population synthesis models to self-consistently track the locations and environmental gas densities of compact binary merger sites throughout the cosmic web.

Dynamical Properties of Internal Shocks Revisited
TL;DR: In this paper, the dynamical properties of plasmas resulting from collision between arbitrarily hot plasma shells, moving at arbitrary speeds, were derived for both the ultra-relativistic and Newtonian velocities, for both hot and cold Plasmas, and the minimum criteria required for the formation of the two-shock wave system were derived.

The Formation of a Blast Wave by a Very Intense Explosion. I. Theoretical Discussion
TL;DR: This paper has now been declassified, and though it has been superseded by more complete calculations, it seems appropriate to publish it as it was first written, without alteration, except for the omission of a few lines, the addition of this summary, and a comparison with some more recent experimental work as discussed by the authors.

Relativistic Rankine-Hugoniot Equations
TL;DR: In this paper, the relativistic form of the Rankine-Hugoniot equations are derived and it is shown that as a consequence of the inequality mentioned earlier that the shock wave velocity is always less than that of light in vacuum for sufficiently strong shocks.
