Physics of shock waves and high-temperature hydrodynamic phenomena
Ya. B. Zel'dovich,Yu. P. Raizer +1 more
TL;DR: The physics of high-temperature hydrodynamic phenomena is discussed in this article, where the authors present interpretations of the physical basis of shockwave and high temperature hydrodynamics and give practical guidance to those who work with these subjects.
Book
Physics of Shock Waves and High-Temperature Hydrodynamic Phenomena
TL;DR: In this paper, the authors discuss the physics of gas dynamics and classical theory of shock waves, including thermal radiation and radiant heat exchange in a medium, and some self-similar processes in gas dynamics.
Journal Article
Gravitational instability: An Approximate theory for large density perturbations
TL;DR: In this paper, an approximate solution for the problem of the growth of perturbations during the expansion of matter without pressure is given, qualitatively correct even when the perturbation is not small.
Journal ArticleDOI
The large-scale structure of the universe: Turbulence, intermittency, structures in a self-gravitating medium
TL;DR: In this paper, the authors show that the density distribution arising at the nonlinear stage of gravitational instability is similar to intermittency phenomena in acoustic turbulence, and that late nonlinear stages of density perturbation growth can be described by the Burgers equation, which is well known in the theory of turbulence.
Journal ArticleDOI
The interaction of matter and radiation in a hot-model universe
Ya. B. Zel'dovich,R. A. Sunyaev +1 more
TL;DR: In this article, it was shown that any injection of energy att>1010 sec (red shiftz <105) leads to deviation from an equilibrium spectrum, and that a period of neutral hydrogen in the evolution of the universe is unavoidable.
