The Flared Disc Project: RXTE and ASCA Observations of X 1822-371
S. Heinz, M. A. Nowak
We present archival RXTE and simultaneous ASCA data of the eclipsing low mass X-ray binary (LMXB) X 1822-371. Our spectral analysis shows that a variety of simple models can fit th…
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…
Monitoring the Short-Term Variability of Cyg X-1: Spectra and Timing
K. Pottschmidt, J. Wilms, R. Staubert +4
We present first results from the spectral and temporal analysis of an RXTE monitoring campaign of the black hole candidate Cygnus X-1 in 1999. The timing properties of this hard s…
RXTE Monitoring of LMC X-3: Recurrent Hard States
J. Wilms, M. A. Nowak, K. Pottschmidt +4
The black hole candidate LMC X-3 varies by a factor of four in the soft X-rays on a timescale of 200 or 100days. We have monitored LMC X-3 with RXTE in three to four week intervals…
Simultaneous EUVE/ASCA/RXTE Observations of NGC 5548
J. Chiang, C. S. Reynolds, O. M. Blaes +5
We present simultaneous observations by EUVE, ASCA, and RXTE of the type~1 Seyfert galaxy NGC 5548. These data indicate that variations in the EUV emission (at keV) appe…
