High-redshift quasars along the Main Sequence
A. Deconto-Machado, A. del Olmo, P. Marziani +2
We aim to evaluate the behaviour of our 22 high-redshift (2.2 < z < 3.7) and high-luminosity (47.39 < Lbol < 48.36) quasars in the context of the 4-Dimensional Eigenvector 1. Our a…
The intermediate-ionization lines as virial broadening estimators for Population A quasars
P. Marziani, A. del Olmo, C. A. Negrete +10
The identification of a virial broadening estimator in the quasar UV rest frame suitable for black hole mass computation at high redshift has become an important issue. We compare…
The ESO Slice Project (ESP) galaxy redshift survey: II. The luminosity function and mean galaxy density
E. Zucca, G. Zamorani, G. Vettolani +16
(Abridged) The ESO Slice Project (ESP) is a galaxy redshift survey we have completed as an ESO Key-Project over ~23 square degrees, in a region near the South Galactic Pole. The su…
Multiwavelength observations of short time-scale variability in NGC 4151. IV. Analysis of multiwavelength continuum variability
R. A. Edelson et al
This paper combines data from the three preceding papers in order to analyze the multi-waveband variability and spectral energy distribution of the Seyfert~1 galaxy NGC~4151 during…
