I will report on long-term monitoring campaign with the NASA Swift mission.
Besides the the NASA Flagship missions Chandra and HST, Swift is NASA's Number 1 mission.
While Swift was launched more than 15 years ago as a Gamma Ray Burst observatory
over the last decade it has morphed into the major tool for time-domain Astrophysics
including studies of Active Galactic Nuclei (AGN). These super-massive accreting black holes
in the center of galaxies are the most luminous persistent object in Universe. However, many
of these AGN display dramatic flux variations on the UV and X-rays which can be explain for
example by absorption and dramatic changes in the accretion rate.
In my talk I will first introduce the NASA Swift observatory and its achivement for Astrophysics
before I will discuss the results of AGN studies with Swift.
