IZw1 observed with XMM-Newton: Low-energy spectral complexity, iron lines, and hard X-ray flares
L. C. Gallo, Th. Boller, W. N. Brandt +2
We present a 20 ks XMM-Newton observation of the prototypical Narrow-Line Seyfert 1 galaxy IZw1. The best-fit model to the data is a double blackbody plus a dominant power-law, on…
Dramatic X-ray Spectral Variability of the Broad Absorption Line Quasar PG2112+059
S. C. Gallagher, W. N. Brandt, Beverley J. Wills +3
With a 1999 ASCA observation, PG2112+059 became notable as the first Broad Absorption Line (BAL) quasar found to exhibit a typical radio-quiet quasar X-ray continuum underlying a l…
Arakelian 564: An XMM-Newton view
C. Vignali, W. N. Brandt, Th. Boller +2
We report on two XMM-Newton observations of the bright narrow-line Seyfert 1 galaxy Ark 564 taken one year apart (2000 June and 2001 June). The 0.6-10 keV continuum is well describ…
The X-ray variability of the Narrow-Line Seyfert 1 galaxy IRAS 13224-3809 from an XMM-Newton observation
L. C. Gallo, Th. Boller, Y. Tanaka +5
We report on the XMM-Newton timing properties of the most X-ray variable, radio-quiet, NLS1 IRAS 13224-3809. IRAS 13224-3809 continues to display the extremely variable behavior th…
The Space Density of High-Redshift QSOs in the GOODS Survey
S. Cristiani, D. M. Alexander, F. Bauer +14
We present a sample of 17 high-redshift (3.5<z<5.2) QSO candidates in the 320 sq.arcmin area of the Great Observatories Origins Deep Survey, selected in the magnitude range 22.45<z…
The X-ray Properties of the Nearby Star-Forming Galaxy IC 342: The XMM-Newton View
F. E. Bauer, W. N. Brandt, B. Lehmer
We present the X-ray properties of IC342 using XMM-Newton. Thirty-five sources are detected coincident with the disk of IC342 (more than tripling the number known), of which ~31 ar…
