Shining light on obscured AGN outflows

AGN can be obscured by gas streams close to the black hole that shield remoteregions from ionising radiation. We witnessed such an event in NGC 5548 where90% of the soft Xrays are blocked by a dense gas stream close to the BLR. Ourjoint observations with XMMNewton, NuSTAR and HST/COS showed UV BAL linesassociated with the Xray absorption and allowed us to characterise this uniqueobscuration event completely. We propose to investigate a similar event inanother Seyfert 1 using the same instruments. Swift monitoring will be used tofind the event, which will be characterised by joint ToO observations withXMMNewton (150 ks), HST/COS (4 orbits) and NuSTAR (50 ks). truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
