Ionization structure of the warm wind in NGC 5548
K. C. Steenbrugge, J. S. Kaastra, D. M. Crenshaw +7
We present the results from our 140 ks XMM-Newton and 500 ks Chandra observation of NGC 5548. The velocity structure of the X-ray absorber is consistent with the velocity structure…
Evidence for Gravitational Infall of Matter onto the Super-Massive Black Hole in the quasar PG 1211+143?
J. N. Reeves, K. Pounds, P. Uttley +5
We report the detection of redshifted iron K-alpha absorption lines in the Chandra LETG spectrum of the narrow-line quasar, PG 1211+143. The absorption lines are observed at 4.22 k…
Simultaneous Ultraviolet and X-ray Observations of the Seyfert Galaxy NGC 4151. I. Physical Conditions in the X-ray Absorbers
S. B. Kraemer, I. M. George, D. M. Crenshaw +9
We present a detailed analysis of the intrinsic X-ray absorption in the Seyfert 1 galaxy NGC 4151 using Chandra/HETGS data obtained 2002 May, as part of a program which included si…
Evidence for Orbital Motion of Material Close to the Central Black Hole of Mrk 766
T. J. Turner, L. Miller, I. M. George +1
Time-resolved X-ray spectroscopy has been obtained for the narrow line Seyfert galaxy Mrk766 from XMM-Newton observations. We present analysis in the energy-time plane of EPIC pn d…
XMM-Newton Spectroscopy of the Starburst Dominated Ultra Luminous Infrared Galaxy NGC 6240
Hagai Netzer, Doron Lemze, Shai Kaspi +5
We present new XMM-Newton observation of the Ultra Luminous Infrared Galaxy (ULIRG) NGC 6240. We analyze the reflecting grating spectrometer (RGS) data, and data from the other ins…
