New XMM-Newton Spectroscopy of the Most Luminous and Distant Quasars
Ohad Shemmer, Niel Brandt
In the two parts of this contribution we describe two related XMM-Newton programs. The first part summarizes our study of the X-ray spectral properties and variability of z>4 quasa…

XMM-Newton Spectroscopy of the Highly Polarized and Luminous Broad Absorption Line Quasar CSO 755
O. Shemmer, W. N. Brandt, S. C. Gallagher +4
We present the results from XMM-Newton observations of the highly optically polarized broad absorption line quasar (BALQSO) CSO 755. By analyzing its X-ray spectrum with a total of…

The X-ray Spectral Properties and Variability of Luminous High-Redshift Active Galactic Nuclei
O. Shemmer, W. N. Brandt, C. Vignali +4
We perform a detailed investigation of moderate-to-high quality X-ray spectra of ten of the most luminous active galactic nuclei (AGNs) known at z>4 (up to z~6.28). This study incl…
