A Comparison of Cosmological Codes: Properties of Thermal Gas and Shock Waves in Large Scale Structures
galaxy: clusters, general – methods: numerical – intergalactic medium – largescale structure of Universe
2011/9/13
Cosmological hydrodynamical simulations are a valuable tool for understanding the growth of large scale structure and the observables connected with this. Yet, comparably little attention has been giv...
Magnetic Fields, Relativistic Particles, and Shock Waves in Cluster Outskirts
Magnetic Fields Relativistic Particles Shock Waves Cluster Outskirts

It is only now, with low-frequency radio telescopes, long exposures with high-resolution X-ray satellites and gamma-ray telescopes, that we are beginning to learn about the physics in the periphery of...
Rarefaction Shock Waves in Collisionless Plasma with Electronic Beam
Collisionless plasma, Supersonic ion-acoustic rarefaction shock waves
2011/9/9
We show that an electronic beam passing through the collisionless plasma of the ”cold” ions and the ”hot” Boltzmann electrons can give rise to the propagation of the supersonic ion-acoustic rarefactio...
Holography and colliding gravitational shock waves in asymptotically AdS_5 spacetime
Holography colliding gravitational shock waves
2010/12/23
Using holography, we study the collision of planar shock waves in strongly coupled N=4 supersymmetric Yang-Mills theory. This requires the numerical solution of a dual gravitational initial value prob...

The recognition that the quark-gluon plasma (QGP) produced in relativistic heavy ion col-
lisions is strongly coupled [1], combined with the ad-vent of gauge/gravity duality (or \holography") [2, 3],...

Shock waves are discontinuities (in the physical properties of a fluid) which behave in an organized manner. The possibility that such waves may occur in oceanic boundary currents is examined with a n...
Organized depth discontinuities involving a balance between steepening and dissipation are usually referred to as shock waves. An analytical “educed gravity” model is used to examine a special kind of...
A number of general circulation models have recently been proposed that compute the steady-state structure of the general circulation. Observation of 18°C water formation, on the other hand, suggest t...
