Revealing the Dusty Warm Absorber in MCG--6-30-15 with the Chandra HETG
J. C. Lee, P. M. Ogle, C. R. Canizares +5
We present detailed evidence for a warm absorber in the Seyfert 1 galaxy MCG--6-30-15 and dispute earlier claims for relativistic O line emission. The HETG spectra show numerous na…
Chandra Observations of the X-ray Narrow-Line Region in NGC 4151
P. M. Ogle, H. L. Marshall, J. C. Lee +1
We present the first high-resolution X-ray spectrum of the Seyfert 1.5 galaxy NGC 4151. Observations with the Chandra High Energy Transmission Grating Spectrometer reveal a spectru…
Scattered Nuclear Continuum and Broad H-alpha in Cygnus A
P. M. Ogle, M. H. Cohen, J. S. Miller +3
We have discovered scattered broad Balmer emission lines in the spectrum of Cygnus A, using the Keck II telescope. Broad H-alpha appears in polarized flux from components on either…
