Powerful relativistic jets in spiral galaxies
galaxies: jets – BL Lacertae objects: general – quasars: general – galaxies: Seyfert – binaries: general
2011/10/9
The discovery of high-energy (E>100 MeV) gamma rays from Narrow-Line Seyfert 1 Galaxies (gamma-NLS1s) has confirmed the presence of powerful relativistic jets in this class of active galactic nuclei (...
Causal Relativistic Fluid Dynamics

2011/10/18
We derive causal relativistic fluid dynamical equations from the relaxation model of kinetic theory as in a procedure previously applied in the case of non-relativistic rarefied gases. By treating spa...
Domain Wall, Stiff Matter and Ultra-Relativistic Particles from a Generalized Double-Component Dark Energy Model

This letter discusses a modified Friedmann-Robertson-Walker cosmology in which the equation of state behaves like p = 3hamrn r; (h;m;n) 2 R. Many interesting features are revealed in particu...

On the Relativistic Beaming and Orientation Effects in Core-Dominated Quasars
active jets quasars
2009/5/19
In this paper, we investigate the relativistic beaming effects
in a well-defined sample of core-dominated quasars using the correlation
between the relative prominence of the core with respect to th...
