Scientific paper

It is shown that three of the compact X-ray sources detected by ROSAT close to the nearby classical Seyfert galaxy NGC 1068 are quasi-stellar objects (QSOs) with redshifts z=0.261, 0.385, and 0.655. Also, using previous optical studies, we show that a total of 11 QSOs brighter than V=19 mag and with redshifts that range from 0.261 to 2.108 lie within a radius of 50' of NGC 1068. The distribution and very high surface density of these QSOs strongly suggest that they are physically associated with NGC 1068 and were ejected from it.
