(Abridged) We present here a long (100ks) XMM-Newton follow-up of the Seyfert 1.8 galaxy ESO113-G010 performed in November 2005, in order to study over a longer time-scale its main X-ray properties....
The Properties and the Evolution of the Highly Ionized Gas in MR2251-178 (2004)
Kaspi, Shai, Netzer, Hagai, Chelouche, Doron, George, Ian M., Nandra, Kirpal, Turner, T. J.
(abridged) We present the first XMM-Newton observations of the radio-quiet quasar MR2251-178 obtained in 2000 and 2002. The EPIC-pn spectra show a power-law continuum with a slope of 1.6 at high...
The Nature of the UV/X-Ray Absorber in PG 2302+029 (2003)
Sabra, Bassem M., Hamann, Fred, Jannuzi, Buell T., George, Ian M., Shields, Joseph C.
We present Chandra X-ray observations of the radio-quiet QSO PG 2302+029. This quasar has a rare system of ultra-high velocity (-56,000 km/s) UV absorption lines that form in an outflow from the...
The Ionized Gas and Nuclear Environment in NGC 3783 II. Averaged HST/STIS and FUSE Spectra (2002)
Gabel, Jack R., Crenshaw, D. Michael, Kraemer, Steven B., Brandt, W. N., George, Ian M., Hamann, Frederick W., ...
We present observations of the intrinsic absorption in the Seyfert 1 galaxy NGC 3783 obtained with the STIS/HST and FUSE. We have coadded multiple STIS and FUSE observations to obtain a high S/N...
Kaspi, Shai, Brandt, W. N., Netzer, Hagai, George, Ian M., Chartas, George, Behar, Ehud, ...
(abridged) The high-resolution X-ray spectrum of NGC 3783 shows several dozen absorption lines and a few emission lines from the H-like and He-like ions of O, Ne, Mg, Si, and S as well as from Fe...
Pian, Elena, Urry, C. Megan, Treves, Aldo, Maraschi, Laura, Penton, Steve, Shull, J. Michael, ...
PKS 2155-304, the brightest BL Lac object in the ultraviolet sky, was monitored with the IUE satellite at ~1 hour time-resolution for ten nearly uninterrupted days in May 1994. The campaign, which...
X-ray Observations of the Broad-Line Radio Galaxy 3C 390.3 (1997)
Leighly, Karen M., O'Brien, Paul T., Edelson, Rick, George, Ian M., Malkan, Matthew A., Matsuoka, Masaru, ...
We present the data and preliminary analysis for a series of 90 ROSAT HRI and two ASCA observations of the broad-line radio galaxy 3C 390.3. These data were obtained during the period 1995 January 2...
