Long-term Monitoring of Active Galactic Nuclei with the NASA Swift mission.

Dirk Grupe

I will report on long-term monitoring campaigns of Active Galactic Nuclei with the NASA Neil Gehrels Swift mission. Swift was launched almost 17 years ago as a Gamma-Ray Burst mission, but quickly turned into a Target-of-Opportunity machine allowing for multi-wavelength, long-term monitoring campaigns. I will show some of these decade-long campaigns and discuss the physical explanations of the strong variability in X-rays and the UV seen in many Narrow-Line Seyfert 1 galaxies. In particular I will talk about WPVS 007, a NLS1 with Broad Absorption Lines, and Mkn 335 which recently has shown strong flaring activity.
