The XMM-Newton X-ray Spectra of the Most X-ray Luminous Radio-quiet ROSAT Bright Survey-QSOs: A Reference Sample for the Interpretation of High-redshift QSO Spectra

Mirko Krumpe, Georg Lamer, Alex Markowitz +1

We present the broadband X-ray properties of four of the most X-ray luminous (L_X >= 10^{45} erg/s in the 0.5-2 keV band) radio-quiet QSOs found in the ROSAT Bright Survey. This un…

Flaring Behavior of the Quasar 3C~454.3 across the Electromagnetic Spectrum

Svetlana G. Jorstad, Alan P. Marscher, Valeri M. Larionov +29

We analyze the behavior of the parsec-scale jet of the quasar 3C~454.3 during pronounced flaring activity in 2005-2008. Three major disturbances propagated down the jet along diffe…
