Active galactic nuclei: what’s in a name?
Paolo Padovani,David M. Alexander,Roberto J. Assef,B. De Marco,Paolo Giommi,Ryan C. Hickox,Gordon T. Richards,Vernesa Smolčić,Evanthia Hatziminaoglou,V. Mainieri,Mara Salvato +10 more
TL;DR: In this paper, the authors present an overview of AGN multi-wavelength properties with the aim of painting their "big picture" through observations in each electromagnetic band from radio to gamma-gamma -rays as well as AGN variability.
Journal ArticleDOI
Discovery of a relation between black hole mass and soft X-ray time lags in active galactic nuclei
B. De Marco,B. De Marco,B. De Marco,Gabriele Ponti,Massimo Cappi,Mauro Dadina,Phil Uttley,Edward M. Cackett,Edward M. Cackett,A. C. Fabian,Giovanni Miniutti +10 more
TL;DR: In this paper, the authors carried out a systematic analysis of time lags between X-ray energy bands in a large sample (32 sources) of unabsorbed, radio quiet active galactic nuclei (AGN), observed by XMM-Newton.
Journal ArticleDOI

TL;DR: A multiwavelength monitoring campaign throughout 2013 suggests that an additional faster jet component has been launching clumps of gas that obscure both the x-ray and UV radiation in NGC 5548, and suggests that the outflow could be associated with a wind from the supermassive black hole's accretion disk.
Journal ArticleDOI

TL;DR: In this article, an extensive multi-satellite campaign on NGC 5548 has revealed this archetypal Seyfert-1 galaxy to be in an exceptional state of persistent heavy absorption.
Journal ArticleDOI
Multiwavelength campaign on Mrk 509 - XII. Broad band spectral analysis
Pierre-Olivier Petrucci,Stéphane Paltani,Julien Malzac,Julien Malzac,Jelle Kaastra,Jelle Kaastra,Massimo Cappi,Gabriele Ponti,B. De Marco,Gerard A. Kriss,Gerard A. Kriss,Katrien C. Steenbrugge,Katrien C. Steenbrugge,Stefano Bianchi,Graziella Branduardi-Raymont,M. Mehdipour,Elisa Costantini,Mauro Dadina,P. Lubinski +18 more
TL;DR: In this paper, the authors used a thermal Comptonization model for the soft X-ray excess of the bright Seyfert 1 Mrk 509 galaxy, which was observed by XMM-Newton and INTEGRAL in October/November 2009.
