We follow the mathematical framework proposed by Bouchut [3] in order to derive equilibrium functions for D1Q3 lattice Boltzmann simulations of the Burgers equation. When a particular convexity proper...
Holography and colliding gravitational shock waves in asymptotically AdS_5 spacetime
Holography colliding gravitational shock waves
font style='font-size:12px;'>
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...
Time-dependent Radiation Transfer in the Internal Shock Model Scenario for Blazar Jets
Time-dependent Radiation the Internal Shock Model
font style='font-size:12px;'>
2010/12/27
We describe the time-dependent radiation transfer in blazar jets, within the internal shock model. We assume that the central engine, which consists of a black hole and an accretion disk, spews out re...

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],...

2010/11/10
By generating function based on the Jackson's q-exponential function and standard exponential function, we introduce a new q-analogue of Hermite and Kampe-de Feriet polynomials. In contrast to standar...

extension is used to model ...
Prospects for Detection of Exoplanet Magnetic Fields Through Bow-Shock Observations During Transits

2010/11/16
An asymmetry between the ingress and egress times was observed in the near-UV light curve
of the transit planet WASP-12b. Such asymmetry led us to suggest that the early ingress in
the UV light curv...

2011/1/7
When galaxy clusters collide, they generate shock fronts in the hot intracluster medium. Observations of these shocks can provide valuable information on the merger dynamics and physical conditions in...
The Role of Diffusive Shock Acceleration on Nonequilibrium Ionization in Supernova Remnant Shocks II: Emitted Spectra
High Energy Astrophysical Phenomena (astro-ph.HE)
font style='font-size:12px;'>
2011/1/6
We present a grid of nonequilibrium ionization models for the X-ray spectra from supernova remnants undergoing efficient diffusive shock acceleration. The calculation follows the hydrodynamics of the ...

2010/3/9
Possible saturation of betatron acceleration of dust particles behind strong shock fronts from supernovae is considered. It is argued that the efficiency of the nonthermal dust destruction should be s...
