The Cambridge-Cambridge ROSAT Serendipity Survey -- IV. The X-ray properties
(Oxford University Press (OUP), 1997)
We present a detailed X-ray spectral analysis in the 0.1–2.4 keV ROSAT band of a complete sample of X-ray-selected AGN using the 80 AGNs in the Cambridge-Cambridge ROSAT Serendipity Survey (68 QSOs and 12 narrow-emission-line ...
The Soft X‐Ray Properties of a Complete Sample of Optically Selected Quasars. II. Final Results
(IOP Publishing, 1997)
We present the final results of a ROSAT PSPC program to study the soft X-ray emission properties of a complete sample of low-z quasars. This sample includes all 23 quasars from the Bright Quasar Survey with z ≤ 0.400 and ...
The X‐Ray Warm Absorber in NGC 3516
(IOP Publishing, 1997)
The Seyfert 1 galaxy, NGC 3516 has been the subject of many absorption line studies at both ultraviolet and X-ray wavelengths. In the UV, strong, broad, variable associated metal line absorption with velocity width ~2000 ...
