Spectral variability in Cygnus X-3
L. Hjalmarsdotter, A. A. Zdziarski, A. Szostek +1
We model the broad-band X-ray spectrum of Cyg X-3 in all states displayed by this source as observed by the Rossi X-ray Timing Explorer. From our models, we derive for the first ti…
A classification of the X-ray and radio states of Cyg X-3 and their long-term correlations
A. Szostek, A. A. Zdziarski, M. L. McCollough
We present a detailed classification of the X-ray states of Cyg X-3 based on the spectral shape and a new classification of the radio states based on the long-term correlated behav…
Effects of the stellar wind on X-ray spectra of Cygnus X-3
A. Szostek, A. A. Zdziarski
We study X-ray spectra of Cyg X-3 from BeppoSAX, taking into account absorption and emission in the strong stellar wind of its companion. We find the intrinsic X-ray spectra are we…
Jet radio emission in Cygnus X-1 and its orbital modulation
A. Szostek, A. A. Zdziarski
We present results of our detailed theoretical study of the observed orbital modulation of the radio emission in Cyg X-1. The modulation occurs due to free-free absorption in the w…
The first near infrared detection of XTE J1118+480 in quiescence
Joanna Mikolajewska, Artur Rutkowski, Denise R. Goncalves +1
We report the first quiescent detection of KV UMa, the optical counterpart of XTE J1118+480 at near infrared. The observed magnitudes and colours are consistent with a K7-M0 V star…
A study of spectra of Cyg X-3 observed by BeppoSAX
A. Szostek, A. A. Zdziarski
We model the ~1-200 keV spectra of Cygnus X-3 observed by BeppoSAX. The continuum, modeled by Comptonization in a hybrid plasma, is modified by the strongly ionized plasma of the s…
