Tracing a Disk Wind in NGC 3516
T. J. Turner, J. N. Reeves, S. B. Kraemer +1
X-ray spectra of AGN often contain signatures indicative of absorption in multiple layers of gas whose ionization-state and covering fraction may vary with time. It has been unclea…
An absorption origin for the X-ray spectral variability of MCG-6-30-15
L. Miller, T. J. Turner, J. N. Reeves
The Seyfert I galaxy MCG-6-30-15 shows one of the best examples of a broad "red wing" of emission in its X-ray spectrum at energies 2 < E < 6.4 keV, commonly interpreted as being c…
Fourier-resolved energy spectra of the Narrow Line Seyfert 1 Mkn 766
P. Arevalo, I. M. McHardy, A. Markowitz +4
We compute Fourier-resolved X-ray spectra of the Seyfert 1 Markarian 766 to study the shape of the variable components contributing to the 0.3-10 keV energy spectrum and their time…
Spitzer/IRS Observations of Seyfert 1.8s and 1.9s: A Comparison with Seyfert 1s and Seyfert 2s
R. P. Deo, D. M. Crenshaw, S. B. Kraemer +4
We present Spitzer Space Telescope mid-infrared spectra of 12 Seyfert 1.8 and 1.9 galaxies over the 5-38 um region. We compare the spectral characteristics of this sample to those…
Low accretion rates at the AGN cosmic downsizing epoch
A. Babic, L. Miller, M. J. Jarvis +3
Context: X-ray surveys of Active Galactic Nuclei (AGN) indicate `cosmic downsizing', with the comoving number density of high-luminosity objects peaking at higher redshifts (z abou…
Probing Unification With Chandra HETGS and XMM-Newton EPIC And RGS Spectroscopy of the Narrow Emission Line Galaxy NGC 2110
Daniel A. Evans, Julia C. Lee, T. Jane Turner +2
We present results from Chandra HETGS (250 ks over two epochs) and XMM-Newton EPIC and RGS (60 ks) observations of NGC 2110, which has been historically classified as a Narrow Emis…
