Searching for Correlations in Simultaneous X-ray and UV Emission in the Narrow-line Seyfert 1 galaxy 1H 0707-495

Understand

We examine simultaneous X-ray and UV light curves from multi-epoch 8 day XMM Newton observations of the narrow line Seyfert 1 galaxy 1H 0707-495.

• The simultaneous observations reveal that both X-ray and UV emission are variable and that the amplitude of the X-ray variations is significantly greater than that of the UV variations in both epochs.
• Using a discrete correlation function (DCF) the X-ray and UV light curves were examined for correlation on timescales up to 7.0 d.
• Low significance (~ 95 percent confidence) correlations with the UV leading the X-ray variations are observed.
