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 ...
There is a wide consensus in the astrophysics community that the mechanism underlying the observed Classical Nova eruptions is a surface thermonuclear runaway. We start this short review with the main...
Cross-helicity effects and turbulent transport in magnetohydrodynamic flow
Cross-helicity effects turbulent transport magnetohydrodynamic
2011/9/28
In the presence of large-scale vortical motions and/or magnetic-field strains, the turbulent cross helicity (velocity--magnetic-field correlation in fluctuations) may contribute to the turbulent elect...
The role of flow geometry in influencing the stability criteria for low angular momentum axisymmetric black hole accretion
the stability criteria low angular momentum axisymmetric black hole accretion
2011/1/11
Using mathematical formalism borrowed from dynamical systems theory, a complete analytical investigation of the critical behaviour of the stationary flow configuration for the low angular momentum axi...
Measuring the Galaxy Cluster Bulk Flow from WMAP data
Cosmology cosmic microwave background observations diffuse radiation
2010/11/15
We have looked for bulk motions of galaxy clusters in the WMAP 7 year data. We isolate the
kinetic Sunyaev-Zeldovich (SZ) signal by filtering the WMAP Q, V and W band maps with multifrequency matched...
Probing the accretion disk - jet connection via instabilities in the inner accretion flow. From microquasars to quasars
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
We present various instability mechanisms in the accreting black hole systems which might indicate at the connection between the accretion disk and jet. The jets observed in microquasars can have a pe...
Magnetosonic Waveguide Model of Solar Wind Flow Tubes
Solar wind MHD waves magnetic flux tubes
2010/9/17
We consider solar wind flow tubes as a magnetosonic waveguide.Assuming a symmetric expansion in edges of slab-modelled waveguide,we study the propagation characteristics of magnetosonic wave in the so...
Mysterious 'dark flow' at the edge of the universe（图）
'dark flow' the edge of the universe
2010/3/26
Astronomers have found that whole clusters of galaxies are moving in convoy towards a single point in the sky. This unexpected motion appears to be separate from the expansion of the universe and the ...
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...

A heliospheric hybrid model：hydrodynamic plasma flow and kinetic cosmic ray transport
heliospheric hybrid hydrodynamic plasma flow kinetic cosmic ray transport
2009/5/27
In this paper we present a new five particle species hybrid model for calculating cosmic ray particle transport and acceleration in a dynamic heliospheric environment. In particular the effects of sol...
Fast Transition between High-soft and Low-soft States in GRS 1915 C 105：Evidence for a Critically Viscous Accretion Flow
accretion discs binaries black hole X-rays
2009/5/19
We present the results of a detailed analysis of RXTE observations
of class ! (Klein-Wolt et al. 2002) which show an unusual state
transition between high-soft and low-soft states in the Galactic mi...
