Orientation effects in quasar spectra: The broad- and narrow-line regions
Orientation effects quasar spectra
2011/1/11
We use the SDSS, along with the NVSS and the WENSS to define a sample of 746 radio-loud quasars and measure their 330MHz to 1.4GHz spectral indexes. Following previous authors we take the spectral ind...
[O III] Equivalent Width and Orientation Effects in Quasars
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
The flux of the [OIII] line is considered to be a good indicator of the bolometric emission of quasars. The observed continuum emission from the accretion disc should instead be strongly dependent on ...
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...
