Simultaneous Ginga and IUE observations of the Seyfert galaxy NGC 3516

A possible connection between the variable X-ray and UV absorption features in NGC 3516 is presently investigated in view of simultaneous X-ray and UV observations. A common origin of the UV and X-ray absorption could not be established, due to the absence of variability in either the X-ray or UV absorption. On the basis of the absorbing properties of a low-luminosity AGN, in the framework of broad absorption-line (BAL) theories, it is suggested that NGC 3516 is consistent with a low-luminosity equivalent of a BAL QSO.
