A multi-epoch spectroscopic study of the BAL quasar APM 08279+5255 II. Emission- and absorption-line variability time lags
F. G. Saturni, D. Trevese, F. Vagnetti +2
The study of high-redshift bright quasars is crucial to gather information about the history of galaxy assembly and evolution. Variability analyses can provide useful data on the p…
A new search for variability-selected active galaxies within the VST SUDARE-VOICE survey: the Chandra Deep Field South and the SERVS-SWIRE area
S. Falocco, D. De Cicco, M. Paolillo +19
This work makes use of the VST observations to select variable sources. We use also the IR photometry, SED fitting and X-ray information where available to confirm the nature of th…
SUDARE-VOICE variability-selection of Active Galaxies in the Chandra Deep Field South and the SERVS/SWIRE region
S. Falocco, M. Paolillo, G. Covone +18
One of the most peculiar characteristics of Active Galactic Nuclei (AGN) is their variability over all wavelengths. This property has been used in the past to select AGN samples an…
Variability-selected Active Galactic Nuclei in the VST-SUDARE/VOICE Survey of the COSMOS Field
D. De Cicco, M. Paolillo, G. Covone +16
Optical variability has proven to be an effective way of detecting AGNs in imaging surveys, lasting from weeks to years. In the present work we test its use as a tool to identify A…
CIV and CIII] reverberation mapping of the luminous quasar PG 1247+267
D. Trevese, M. Perna, F. Vagnetti +2
So far the masses of about 50 active galactic nuclei have been measured through the reverberation mapping technique (RM). Most measurements have been performed for objects of moder…
A multi-epoch spectroscopic study of the BAL quasar APM 08279+5255: I. C IV absorption variability
D. Trevese, F. G. Saturni, F. Vagnetti +3
Broad Absorption Lines indicate gas outflows with velocities from thousands km/s to about 0.2 the speed of light, which may be present in all quasars and may play a major role in t…
