• Do X-ray binary spectral state transition luminosities vary? (2003, background): “…and comparisons of the low/hard state and high/soft state luminosities have been presented for some individual sources (see e.g. Zhang et al. 1997; Zdziarski et al. 2002 as well as the observations discussed below), and the transition luminosity has been estimated in Eddington units for one…”

• Combined long and short timescale X-ray variability of NGC 4051 with RXTE and XMM-Newton (2003, background): “In the standard Comptonisation models for the production of X-ray emission, different physical regimes apply to low and high states, with a higher seed photon flux in the high state, leading to a cooler Comptonising corona (eg Zdziarski et al. 2002).”
• Correlations between X-ray and radio spectral properties of accreting black holes (2002, methodology): “…treatment should in general include at least two line components, narrow and broad, with the broadening (e.g. Gaussian or disc-like) and redshift of the latter applied in the same way to the reflection (e.g., Życki et al. 1998, 1999; GCR00; Lubiński & Zdziarski 2001; Zdziarski et al. 2002a).”
• GX 339—4: the distance, state transitions, hysteresis and spectral correlations (2004, background): “…is that whereas Cyg X-1 is a persistent source, in which the bolometric luminosity (and presumably the accretion rate) varies only by ∼5 or so (Zdziarski et al. 2002, hereafter Z02), GX 339–4 is a transient, in which accretion is unstable and the accretion rate in the vicinity of the black…”
