Transient and Highly Polarized Double-Peaked H-alpha Emission in the Seyfert 2 Nucleus of NGC 2110
Edward C. Moran, Aaron J. Barth, Michael Eracleous +1
We have discovered an extremely broad, double-peaked H-alpha emission line in the polarized flux spectrum of NGC 2110, establishing that this well-studied Seyfert 2 galaxy contains…
"Hidden" Seyfert 2 Galaxies in the Chandra Deep Field North
Carolin N. Cardamone, Edward C. Moran, Laura E. Kay
We have compared the X-ray--to--optical flux ratios (F_x/F_opt) of absorbed active galactic nuclei (AGNs) in the Chandra Deep Field North (CDF-N) with those of nearby, optically cl…
UV Imaging Polarimetry of the peculiar Seyfert 2 galaxy Mrk 477
Makoto Kishimoto, Laura E. Kay, Robert Antonucci +3
We present the results of UV imaging polarimetry of the Seyfert 2 galaxy Mrk 477 taken by the Faint Object Camera onboard the Hubble Space Telescope (HST). From a previous HST UV i…
UV Imaging Polarimetry of the Seyfert 2 Galaxy Mrk 3
Makoto Kishimoto, Laura E. Kay, Robert Antonucci +3
We present UV imaging polarimetry data of the Seyfert 2 galaxy Mrk 3 taken by the Hubble Space Telescope. The polarized flux is found to be extended to ~1 kpc from the nucleus, and…
A Composite Seyfert 2 X-ray Spectrum: Implications for the Origin of the Cosmic X-ray Background
Edward C. Moran, Laura E. Kay, Marc Davis +2
We present a composite 1-10 keV Seyfert 2 X-ray spectrum, derived from ASCA observations of a distance-limited sample of nearby galaxies. All 29 observed objects were detected. Abo…
The Frequency of Polarized Broad Emission Lines in Type 2 Seyfert Galaxies
E. C. Moran, A. J. Barth, L. E. Kay +1
We have discovered polarized broad emission lines in five type 2 Seyfert galaxies (NGC 424, NGC 591, NGC 2273, NGC 3081, and NGC 4507), establishing that these objects are type 1 S…
The X-ray spectra and spectral variability of intermediate type Seyfert galaxies: ASCA observations of NGC 4388 and ESO 103-G35
Karl Forster, Karen M. Leighly, Laura E. Kay
The X-ray spectra of two intermediate type Seyfert galaxies are investigated using ASCA observations separated by more than a year. Both NGC 4388 and ESO 103-G35 exhibit strong, na…
Spectropolarimetry of the Luminous Narrow-Line Seyfert Galaxies IRAS 20181-2244 and IRAS 13224-3809
Laura E. Kay, A. M. Magalhaes, F. Elizalde +1
We observed the narrow-line Seyfert 1 galaxies IRAS 20181-2244 and IRAS 13324-3809 with a new spectropolarimeter on the RC spectrograph at the CTIO 4m telescope. Previously it had…
A Hidden Broad-Line Region in the Weak Seyfert 2 Galaxy NGC 788
Laura E. Kay, Edward C. Moran
We have detected a broad H alpha emission line in the polarized flux spectrum of the Seyfert 2 galaxy NGC 788, indicating that it contains an obscured Seyfert 1 nucleus. While such…
The Optical Polarization and Warm Absorber in IRAS 17020+4544
Karen M. Leighly, Laura E. Kay, Beverley J. Wills +2
We report the detection of ionized absorption in the ASCA spectrum of the narrow-line Seyfert 1 galaxy IRAS 17020+4544. Subsequent optical spectropolarimetry revealed high polariza…
