Finding AGN in Deep X-ray Flux States with Swift
We report on our ongoing project of finding Active Galactic Nuclei (AGN) that
go into deep X-ray flux states detected by Swift. Swift is performing an
extensive study on the flux and spectral variability of AGN using Guest
Investigator and team fill-in programs followed by triggering XMM_Newton for
deeper follow-up observations. So far this program has been very successful and
has led to a number of XMM-Newton follow up observations, including Mkn 335, PG
0844+349, and RX J2340.8-5329. Recent analysis of new Swift AGN observations
reveal several AGN went into a very low X-ray flux state, particularly
Narrow-Line Seyfert 1 galaxies. One of these is RX J2317-4422, which dropped by
a factor of about 60 when compared to the ROSAT All-Sky Survey.Comment: 6 pages, 3 figures, Proceedings of the "10 Years of Swift" Meeting
