Fundamental Physics and Relativistic Laboratory Astrophysics with Extreme Power Lasers
Fundamental Physics Relativistic Laboratory Astrophysics Extreme Power Lasers
2012/2/23
The prospects of using extreme relativistic laser-matter interactions for laboratory astrophysics are discussed. Laser-driven process simulation of matter dynamics at ultra-high energy density is prop...
A consistent first-order model for relativistic heat flow
consistent first-order model relativistic heat flow
2011/10/18
This paper revisits the problem of heat conduction in relativistic fluids, associated with issues concerning both stability and causality. It has long been known that the problem requires information ...
Intracluster Medium reheating by relativistic jets
Intracluster Medium reheating by relativistic jets
2011/10/18
Galactic jets are powerful energy sources reheating the intra-cluster medium in galaxy clusters. Their crucial role in the cosmic puzzle, motivated by observations, has been established by a great num...
Modelling interaction of relativistic and non-relativistic winds in binary system PSR B1259-63/SS2883 - II. Impact of magnetization and anisotropy of the pulsar wind
HD – shock waves - pulsars: binaries
2011/10/19
In this paper, we present a numerical study of the properties of the flow produced by the collision of a magnetized anisotropic pulsar wind with its environment in binary system. We compare the impact...
A Fast Numerical Scheme for Causal Relativistic Hydrodynamics with Dissipation
relativistic hydrodynamics relativistic dissipation relativity kinetic theory methods: numerical
2011/9/13
In this paper, we develop a stable and fast numerical scheme for relativistic dissipative hydrodynamics based on Israel-Stewart theory. Israel-Stewart theory is a stable and causal description of diss...
A white dwarf companion to the relativistic pulsar PSR J1141-6545
methods photometry – binaries close – pulsars general – stars neutron white dwarfs – individual PSRJ1141− 6545
2010/11/10
Pulsars with compact companions in close eccentric orbits are unique laboratories for testing general relativity and alternative theories of gravity. Moreover, they are excellent targets for future gr...
A recent progress in the study of $\gamma$-ray jets is reviewed, with a focus on some theoretical interpretations of the VHE emission from M87, and possibly other misaligned blazars; the connection be...
Magnetic field amplification and electron acceleration to near-energy equipartition with ions by a mildly relativistic quasi-parallel plasma protoshock
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
The prompt emissions of gamma-ray bursts are seeded by radiating ultrarelativistic electrons. Internal shocks propagating through a jet launched by a stellar implosion, are expected to amplify the mag...
Computation of synthetic spectra from simulations of relativistic shocks
High Energy Astrophysical Phenomena (astro-ph.HE) Classical Physics (physics.class-ph)
2010/12/24
Particle-in-cell (PIC) simulations of relativistic shocks are in principle capable of predicting the spectra of photons that are radiated incoherently by the accelerated particles. The most direct met...
Lindblad resonance torques in relativistic discs: II. Computation of resonance strengths

Lindblad resonances have been suggested as an important mechanism for angular momentum transport and heating in discs in binary black hole systems.
Relativistic Dissipative Accretion Flow onto Black Hole
Extended Irreversible Thermodynamics (EIT) Black Hole
2010/3/9
Dissipations, e.g. heat flow and bulk and shear viscosities, cause the transport of energy, momentum and angular momentum, which is the essence of accretion of matters onto celestial objects. Dissipat...
