Timing analysis of the Seyfert-1 galaxy MCG-6-30-15 with XMM-Newton data
N. La Palombara, S. Molendi, J. Wilms +1
We present the main results of a deep timing analysis (in the 0.2-10 keV energy band) of the bright Seyfert-1 galaxy MCG-6-30-15 performed on XMM-Newton data. The light-curves and…
Confirmation of Two Cyclotron Lines in Vela X-1
I. Kreykenbohm, W. Coburn, J. Wilms +4
We present pulse phase-resolved X-ray spectra of the high mass X-ray binary Vela X-1 using the Rossi X-ray Timing Explorer. We observed Vela X-1 in 1998 and 2000 with a total obser…
Magnetic Fields of Accreting X-Ray Pulsars with the Rossi X-Ray Timing Explorer
W. Coburn, W. A. Heindl, R. E. Rothschild +5
Using a consistent set of models, we parameterized the X-ray spectra of all accreting pulsars in the Rossi X-ray Timing Explorer database which exhibit Cyclotron Resonance Scatteri…
A Her X-1 Turn-On: Using the pulse profile to probe the outer edge of an accretion disk
M. Kuster, J. Wilms, R. Staubert +5
The X-ray binary pulsar Her X-1 shows a wide variety of long and short term variabilities in the X-ray light curve. The 35 d variability of the source is interpreted as the influen…
Long Term Variability of Cyg X-1 I. X-ray spectral-temporal correlations in the hard state
K. Pottschmidt, J. Wilms, M. A. Nowak +6
We present the long term evolution of the timing properties of the black hole candidate Cygnus X-1 in the 0.002-128 Hz frequency range as monitored from 1998 to 2001 with the RXTE.…
