      Lags measured from correlated X-ray/UV/optical monitoring of AGN allow us to determine whether UV/optical variability is driven by reprocessing of X-rays or X-ray variability is driven by UV/optical seed photon variations. ...
    • McHardy, I.; Connolly, S.; Horne, K.; Cackett, E.; Gelbord, J.; Peterson, B.; Pahari, M.; Gehrels, N.; Goad, M.; Lira Teillery, Paulina; Arevalo, P.; Baldi, R.; Brandt, N.; Breedt, E.; Chand, H.; Dewangan, G.; Done, C.; Elvis, M.; Emmanoulopoulos, D.; Fausnaugh, M.; Kaspi, S.; Kochanek, C.; Korista, K.; Papadakis, I.; Rao, A.; Uttley, P.; Vestergaard, M.; Ward, M. (Oxford University Press, 2018)
      We report the results of intensive X-ray, UV, and optical monitoring of the Seyfert 1 galaxy NGC 4593 with Swift. There is no intrinsic flux-related spectral change in any variable component with small apparent variations ...
