Correlated X-ray/Optical Variability in the Quasar MR2251-178
Emission from Active Galactic Nuclei is known to vary strongly over time over a wide energy band, but the origin of the variability and especially of the inter-band correlations is still not well established. Here we present the results of our X-ray and optical monitoring campaign of the quasar MR 2251-178, covering a period of 2.5 years. The X-ray 2–10 keV flux is remarkably well correlated wi...
متن کاملExtreme X - ray variability in the luminous quasar PDS 456
We present evidence from BeppoSAX and XMM-Newton of extreme X-ray variability in the high luminosity radio-quiet quasar PDS 456, the most luminous known AGN at z < 0.3. Repeated X-ray flaring is found in PDS 456, over the duration of the 340 ksec long BeppoSAX observation. The X-ray flux doubles in just 30 ksec, whilst the total energy output of the flaring events is as high as 10 51 erg. Under...
متن کاملCorrelated Optical and X - ray Variability in LMC X – 2
We have obtained high time resolution (seconds) photometry of LMC X–2 in December 1997, simultaneously with the Rossi X-ray Timing Explorer (RXTE), in order to search for correlated X-ray and optical variability on timescales from seconds to hours. We find that the optical and X-ray data are correlated only when the source is in a high, active X-ray state. Our analysis shows evidence for the X-...
متن کاملCorrelated X-ray and Optical Variability in X-ray Binaries
It has long been known that X-ray and optical/UV variability in active X-ray binaries is sometimes correlated. The expectation has been that this arises from rapid reprocessing of X-rays into longer wavelength photons, and hence that the lags between the bandpasses can be used to reconstruct an echomap of the binary, revealing the geometry and spatial scale of reprocessing sites. I will review ...
متن کاملCorrelated X-ray and optical variability in KV UMa
We present coordinated X-ray and optical observations of the X-ray transient KV UMa (= XTE J1118+480) at high time resolution. The optical variation associated with spikes in the X-rays consist of a dip preceding the spike by 0-5 s, and a peak following it. The cross-correlation function between X-rays and optical has the same shape. It rises sharply, within 30ms of the peak of the X-rays. The ...
