BeppoSAX observations of 3C 273
Francesco Haardt
We present preliminary results of BeppoSAX AO1 observations of 3C 273 performed in January 1997. We also present a close comparison with data obtained during the satellite SVP, in…
Properties of the X-ray pulsar GX 301-2 in hard X-rays
V. Borkus, A. Kaniovsky, R. Sunyaev +5
In 1993-1994 a series of observations of the X-ray pulsar GX 301-2 by HEXE onboard Mir-Kvant was made. A period of pulsations was measured (it varied between 675 and 678 s) and pul…
Analyzing X-ray variability by State Space Models
M. König, J. Timmer, R. Staubert
In recent years, autoregressive models have had a profound impact on the description of astronomical time series as the observation of a stochastic process. These methods have adva…
Pulse Phase Spectroscopy of A 0535+26 during its 1994 giant outburst observed with OSSE
M. Maisack, J. E. Grove, E. Kendziorra +3
We present pulse phase spectroscopy of A 0535+26 in the energy range 35-200 keV from OSSE observations of its giant outburst in 1994. We discuss the phase dependence of the continu…
