Abstract | One joint Chandra/HST ToO observation (50 ks/3 orbits each) is proposed of the changing-look AGN Mrk 1018. This is to be triggered if the optical flux increases/decreases by at least a factor of two compared to the highest/lowest optical flux seen over the period 2016-2020. The major outburst in summer 2020 indicates that Mrk 1018 is still dynamic and unpredictable. Chandra data will be used to study how the X-ray emitting corona responds to another change in the accretion rate, whereas joint UV data are needed to study the X-ray corona/UV accretion disk connection during a major reconfiguration of the system. In addition, the HST data will check whether the UV outflow discovered in 2016 is directly linked to Mrk 1018's significant drop in luminosity. |
