Cygnus X-1 from RXTE: Monitoring the short term variability
K. Pottschmidt, J. Wilms, R. Staubert +3
We present temporal and spectral results from monitoring Cygnus X-1 with the Rossi X-ray Timing Explorer (RXTE) in 1998 and 1999. We concentrate on the long term evolution of the h…
Discovery of Recurring Soft to Hard State Transitions in LMC X-3
J. Wilms, M. A. Nowak, K. Pottschmidt +3
We present the analysis of an RXTE monitoring campaign of the canonical soft state black hole candidates LMC X-1 and LMC X-3. In contrast to LMC X-1, which does not exhibit any per…
A Good Long Look at the Black Hole Candidates LMC X-1 and LMC X-3
M. A. Nowak, J. Wilms, W. A. Heindl +3
We present results from 170ksec long RXTE observations of LMC X-1 and LMC X-3, taken in 1996 December, where their spectra can be described by a disc black body plus an additional…
RXTE Studies of Cyclotron Lines in Accreting Pulsars
W. A. Heindl, W. Coburn, D. E. Gruber +7
In this paper, we summarize the RXTE measurements of cyclotron resonance scattering features in 8 accreting pulsars. The wide bandpass and modest resolution of the RXTE instruments…
Multiple Cyclotron Lines in the Spectrum of 4U 0115+63
W. A. Heindl, W. Coburn, D. E. Gruber +5
We report phase resolved spectroscopy of the transient accreting pulsar, 4U0115+63. For the first time, more than two cylotron resonance scattering features are detected in the spe…
Multifrequency Observations of the Virgo Blazars 3C 273 and 3C 279 in CGRO Cycle 8
W. Collmar, S. Benlloch, J. E. Grove +15
We report first observational results of multifrequency campaigns on the prominent Virgo blazars 3C 273 and 3C 279 which were carried out in January and February 1999. Both blazars…
Temporal Evolution of X-ray Lags in Cygnus X-1
K. Pottschmidt, J. Wilms, M. A. Nowak +3
We present the long term evolution of the frequency-dependent X-ray time lags of the black hole candidate Cygnus X-1 as measured in 1996 and 1998 with the Rossi X-ray Timing Explor…
On the inability of Comptonization to produce the broad X-ray iron lines observed in Seyfert nuclei
C. S. Reynolds, J. Wilms
It has recently been suggested that Compton downscattering may give rise to the broad iron lines seen in the X-ray spectra of Seyfert 1 galaxies. This challenges the standard model…
