XMM-Newton observations of warm absorbers in PG quasars
C. E. Ashton, M. J. Page, A. J. Blustin +5
We present XMM-Newton EPIC observations of warm absorbers in the quasars PG 1114+445 and PG 1309+355, both of which exhibit evidence for absorption by warm material in the line-of-…
XMM-Newton spectroscopy of high redshift quasars
C. Brocksopp, E. M. Puchnarewicz, K. O. Mason +2
We present XMM-Newton X-ray spectra and optical photometry of four high redshift (z=2.96-3.77) quasars, [HB89] 0438-436, [HB89] 2000-330, [SP89] 1107+487 and RX J122135.6+280613; o…
The optical to soft X-ray spectrum of the ultrasoft broad-line AGN RE J2248-511
R. L. C. Starling, E. M. Puchnarewicz, E. Romero-Colmenero +1
We present a series of monitoring observations of the ultrasoft broad-line AGN RE J2248-511 with XMM-Newton. Previous X-ray observations showed a transition from a very soft state…
XMM-Newton Surveys of the CFRS Fields - I: The Sub-mm/X-ray relation
Timothy J. Waskett, Stephen A. Eales, Walter K. Gear +7
First results from XMM-Newton observations of the Canada France Redshift Survey (CFRS) 3hr, 10hr and 14hr fields are presented. Limited regions of two of the XMM surveys (3 and 14h…
Do NLS1s and ultrasoft AGN have irradiated, warped accretion disks?
E. M. Puchnarewicz, R. Soria
When Beppo-SAX measured the 0.1--12 keV spectrum of RE J1034+396, observations in the optical, UV and EUV were also taken within a few weeks. This multiwavelength spectrum placed v…
BeppoSAX observations of Narrow-Line Seyfert 1 galaxies:I. Ton S 180
A. Comastri, F. Fiore, M. Guainazzi +10
We report on the first spectrum up to 10 keV of the bright narrow-line Seyfert 1 galaxy Ton S 180, obtained with the imaging instruments onboard BeppoSAX. This is the first observe…
