Revealing a hard X-ray spectral component that reverberates within one light hour of the central supermassive black hole in Ark 564
M. Giustini, T. J. Turner, J. N. Reeves +4
Ark 564 (z=0.0247) is an X-ray-bright NLS1. By using advanced X-ray timing techniques, an excess of "delayed" emission in the hard X-ray band (4-7.5 keV) following about 1000 secon…
The hard X-ray spectrum of NGC 1365: scattered light, not black hole spin
L. Miller, T. J. Turner
Active Galactic Nuclei (AGN) show excess X-ray emission above 10 keV compared with extrapolation of spectra from lower energies. Risaliti et al. have recently attempted to model th…
Observations of Outflowing UV Absorbers in NGC 4051 with the Cosmic Origins Spectrograph
S. B. Kraemer, D. M. Crenshaw, J. P. Dunn +6
We present new Hubble Space Telescope (HST)/Cosmic Origins Spectrograph observations of the Narrow-Line Seyfert 1 galaxy NGC 4051. These data were obtained as part of a coordinated…
X-ray Characteristics of NGC 3516: A View through the Complex Absorber
T. J. Turner, L. Miller, S. B. Kraemer +1
We consider new Suzaku data for NGC 3516 taken during 2009, along with other recent X-ray observations of the source. The cumulative characteristics of NGC 3516 cannot be explained…
A broad-band X-ray view of the Warm Absorber in radio-quiet quasar MR2251-178
J. Gofford, J. N. Reeves, T. J. Turner +6
We present the analysis of a new broad-band X-ray spectrum (0.6-180.0 keV) of the radio-quiet quasar MR 2251-178 which uses data obtained with both Suzaku and the Swift/BAT. In acc…
Contemporaneous Chandra HETG and Suzaku X-ray Observations of NGC 4051
A. P. Lobban, J. N. Reeves, L. Miller +4
We present the results of a deep 300 ks Chandra HETG observation of the highly variable narrow-line Seyfert Type 1 galaxy NGC 4051. The HETG spectrum reveals 28 significant soft X-…
