Separation of Different Contributions to the Total X-ray Luminosity in Gamma-ray Loud Blazars
(Science Press, 2005-12)
The relativistic beaming model has been successfully used to explain many of the observational properties of active galactic nuclei. In this model the total emission is formed by two components, one beamed, one unbeamed. ...
Spiral-like structure at the centre of nearby clusters of galaxies
