|Title:||Anatomy of the AGN in NGC 5548: Evidence for an unexpected, new, heavy, variable and complex absorber||Authors:||CAPPI, MASSIMO

|Issue Date:||2014||First Page:||44||Abstract:||After a very successful multi-satellite campaign on Mrk 509 in 2009, we conducted a similar campaign on the AGN NGC 5548 in 2013. The source appeared strongly absorbed in the soft X-rays during this campaign, and signatures of strong outflows were also present in the UV. A talk (PI: J. Kaastra) of an overview of this campaign is also proposed to this conference. I propose here to present the EPIC results from the campaign focusing on the analysis of the new, heavy, and variable absorber found in this otherwise archetypical type-1 source. I will put these results into context by reviewing other recent evidence for massive (either highly ionized or neutral) absorbers along the line of sight of other type-1 AGNs, and will present some of their possible interpretations under discussion in the literature: from eclipsing broad line region clouds, to clumpy dusty tori and accretion disc winds. Finally, I will argue that the combination of our new X-ray and UV data for NGC5548 places interesting and severe constraints on some of these interpretations.||URI:||http://hdl.handle.net/20.500.12386/12142||Bibcode ADS:||2014xru..confE..44C|
