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…

The Variable X-ray Spectrum of Markarian 766 - II. Time-Resolved Spectroscopy

T. J. Turner, L. Miller, J. N. Reeves +1

CONTEXT: The variable X-ray spectra of AGN systematically show steep power-law high states and hard-spectrum low states. The hard low state has previously been found to be a compon…

Relativistic Iron K Emission and absorption in the Seyfert 1.9 galaxy MCG-5-23-16

V. Braito, J. N. Reeves, G. C. Dewangan +9

We present the results of the simultaneous deep XMM and Chandra observations of the bright Seyfert 1.9 galaxy MCG-5-23-16, which is thought to have one of the best known examples o…

A Photoionization Model For The Soft X-Ray Spectrum Of NGC 4151

B. K. Armentrout, S. B. Kraemer, T. J. Turner

We present analysis of archival data from multiple XMM-Newton observations of the Seyfert 1 galaxy NGC 4151. Spectral data from the RGS instruments reveal several strong soft X-ray…
