Black hole mass estimates in quasars - A comparative analysis of high- and low-ionization lines
P. Marziani, A. del Olmo, M. A. Martinez-Carballo +7
The inter-line comparison between high- and low-ionization emission lines has yielded a wealth of information on the quasar broad line region (BLR) structure and dynamics, includin…
HE0359-3959: an extremely radiating quasar
M. L. Martínez-Aldama, A. Del Olmo, P. Marziani +3
We present a multiwavelength spectral study of the quasar HE0359-3959, which has been identified as an extreme radiating source at intermediate redshift (z=1.5209). Along the spect…
Blue outliers among intermediate redshift quasars
P. Marziani, J. W. Sulentic, G. M. Stirpe +3
[Oiii]λλ4959,5007 "blue outliers" -- that are suggestive of outflows in the narrow line region of quasars -- appear to be much more common at intermediate z (high luminosity) than…
