Intrinsic Curvature in the X-ray Spectra of BL Lacertae Objects
Eric S. Perlman, Greg Madejski, Markos Georganopoulos +10
We report results from {\it XMM-Newton} observations of thirteen X-ray bright BL Lacertae objects, selected from the {\it Einstein} Slew Survey sample. The survey was designed to l…
Quasars and the Big Blue Bump
Zhaohui Shang, Michael S. Brotherton, Richard F. Green +10
We investigate the ultraviolet-to-optical spectral energy distributions (SEDs) of 17 active galactic nuclei (AGNs) using quasi-simultaneous spectrophotometry spanning 900-9000 Angs…
BL Lac X-ray Spectra: simpler than we thought
Eric S. Perlman, Timothy Daugherty, Anuradha Koratkar +10
We report results from {\it XMM-Newton} observations of thirteen X-ray bright BL Lacertae objects, selected from the {\it Einstein} Slew Survey sample. The spectra are generally we…
The Ionized Gas and Nuclear Environment in NGC 3783. I. Time-Averaged 900 ks Chandra Grating Spectroscopy
S. Kaspi, W. N. Brandt, I. M. George +15
We present results from a 900 ks exposure of NGC 3783 with the High-Energy Transmission Grating Spectrometer on board the Chandra X-ray Observatory. The resulting X-ray spectrum ha…
HST STIS Observations of PG 0946+301: the Highest Quality UV Spectrum of a BALQSO
Nahum Arav, Martijn de Kool, Kirk T. Korista +16
We describe deep (40 orbits) HST/STIS observations of the BALQSO PG 0946+301 and make them available to the community. These observations are the major part of a multi-wavelength c…
Evidence for an accelerating wind as the broad-line region in NGC 3516
J. B. Hutchings, G. A. Kriss, R. F. Green +4
Spectroscopic data in wavelengths 900--3000A have been obtained in a low flux state of the nucleus of the Seyfert 1 galaxy NGC 3516. The line profiles show P Cygni characteristics,…
