Stability of the Cyclotron Resonance Scattering Feature in Her X-1 with RXTE

D. E. Gruber, W. A. Heindl, R. E. Rothschild +4

Five observations of the hard X-ray spectrum of Her X-1 from \xte show that the keV energy of the cyclotron scattering line is constant within statistics of a few percent…

XMM-EPIC observation of MCG-6-30-15: Direct evidence for the extraction of energy from aspinning black hole?

Joern Wilms, Christopher S. Reynolds, Mitchell C. Begelman +4

We present XMM-Newton European Photon Imaging Camera (EPIC) observations of the bright Seyfert 1 galaxy MCG-6-30-15, focusing on the broad Fe K line at ~6keV and the associated…

Quasi-Periodic Oscillation in Seyfert galaxies: Significance levels. The Case of Mrk 766

S. Benlloch, J. Wilms, R. Edelson +2

We discuss methods to compute significance levels for the existence of quasi-periodic oscillations (QPOs) in Active Galactic Nuclei (AGN) which take the red-noise character of the…

RXTE monitoring of Centaurus A

S. Benlloch, R. E. Rothschild, J. Wilms +3

We report on the analysis from ~110 ks of X-ray observations of Centaurus A carried out with the Proportional Counter Array (PCA) and the High Energy X-ray Timing Experiment (HEXTE…

Discovery of a Cyclotron Resonant Scattering Feature in the RXTE Spectrum of 4U 0352+309 (X Per)

W. Coburn, W. A. Heindl, D. E. Gruber +4

We have discovered a ~29 keV Cyclotron Resonant Scattering Feature (CRSF) in the X-Ray spectrum of 4U 0352+309 (X Per) using observations taken with the Rossi X-Ray Timing Explorer…
