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 ...
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...
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 Self-similar Flow Behind a Shock Wave in a Gravitating or Non-gravitating Gas with Heat Conduction and Radiation Heat-flux
Shock wave self-similar flow self-gravitational effects heat transfer effects variable initial density variable total energy
2010/9/15
The propagation of a spherical shock wave in an ideal gas with heat conduction and radiation heat-flux, and with or without self-gravitational effects, is investigated. The initial density of the gas ...
