[34.08] X-ray and lower energy variability in NGC 3516 and other AGN

R. Edelson (UCLA)

The launch of RXTE has made possible the first evenly-sampled, long-term X-ray monitoring of AGN, and the most important advances in our understanding of X-ray variability since EXOSAT. The most important studies to date have involved measuring the turnover in the X-ray fluctuation power density spectrum of NGC 3516 and the (lack of) correlation between X-ray and optical variations in NGC 7469. I will discuss the implications of these results along with future campaigns that could utilize Chandra or XMM to sample rapid variability while RXTE does long-term monitoring.
