Transient Relativistically-Shifted Lines as a Probe of Black Hole Systems

T. J. Turner, S. B. Kraemer, J. N. Reeves

X-ray spectra of Seyfert galaxies have revealed a new type of X-ray spectral feature, one which appears to offer important new insight into the black hole system. XMM/Chandra revea…

The XMM-Newton Iron Line Profile of NGC 3783

J. N Reeves, K. Nandra, I. M. George +3

We report on observations of the iron K line in the nearby Seyfert 1 galaxy, NGC 3783, obtained in a long, 2 orbit (240 ks) XMM-Newton observation. The line profile obtained exhibi…

A warm hot intergalactic medium towards 3C 120?

B. McKernan, T. Yaqoob, R. Mushotzky +2

We observed the Seyfert I active galaxy/broad line radio galaxy 3C120 with the Chandra high energy transmission gratings and present an analysis of the soft X-ray spectrum. We iden…

The Ionized Gas and Nuclear Environment in NGC 3783. IV. Variability and Modeling of the 900 ks CHANDRA Spectrum

H. Netzer, S. Kaspi, E. Behar +12

We present a detailed spectral analysis of the data obtained from NGC 3783 during the period 2000-2001 using Chandra. This analysis leads us to the following results. 1) NGC 3783 f…

Fe XXV and Fe XXVI Diagnostics of the Black Hole and Accretion Disk in Active Galaxies: Chandra Time-Resolved Spectroscopy of NGC 7314

T. Yaqoob, I. M. George, T. R. Kallman +3

We report the detection of Fe XXV and Fe XXVI emission lines from a Chandra HETGS observation of the Seyfert~1 galaxy NGC 7314, made simultaneously with RXTE. The lines are re…

Elemental Abundances in NGC 3516

T. J. Turner, S. B. Kraemer, R. F. Mushotzky +2

We present RGS data from an XMM-Newton observation of the Seyfert 1 galaxy NGC 3516, taken while the continuum source was in an extreme low state. The spectrum shows numerous emiss…
