Journal ArticleDOI
Revisiting dual AGN candidates with spatially resolved LBT spectroscopy: The impact of spillover light contamination
Bernd Husemann,Jochen Heidt,A. De Rosa,Cristian Vignali,Stefano Bianchi,Tamara Bogdanovic,S. Komossa,Zsolt Paragi +7 more
TL;DR: In this paper, the authors characterise and confirm the presence of two independent active galactic nuclei separated by a few kiloparsec in seven strongly interacting galaxies previously selected from the Sloan Digital Sky Survey (SDSS) as Seyfert-Seyfert pairs based on emission-line ratio diagnostics.
Journal ArticleDOI
XMM-Newton reveals a Seyfert-like X-ray spectrum in the z = 3.6 QSO B1422+231
Mauro Dadina,Cristian Vignali,Massimo Cappi,Giorgio Lanzuisi,Gabriele Ponti,B. De Marco,George Chartas,Margherita Giustini +7 more
TL;DR: In this paper, the authors used X-ray data to probe the matter inflow at the very center of a QSO at z = 3.62 and found that the primary emission of B1422+231 is most probably dominated by the thermal Comptonization of UV seed photons in a corona with kT ~ 40 keV.

TL;DR: In this article, the authors summarize the scientific results associated with the first release of the XXL dataset, which occurred in mid-2016, and review several arguments for increasing the survey depth to 40 ks during the next decade of XMM operations.
Journal ArticleDOI
X-ray observations of dust obscured galaxies in the Chandra Deep Field South
Amalia Corral,I. Georgantopoulos,Andrea Comastri,Piero Ranalli,A. Akylas,Mara Salvato,Giorgio Lanzuisi,Cristian Vignali,Cristian Vignali,L. Koutoulidis +9 more
TL;DR: In this paper, the authors presented the properties of X-ray detected dust obscured galaxies (DOGs) in the Chandra Deep Field South (CDF-S) and combined these data with the 3Ms XMM-Newton survey of the CDF-S.
