Characterisation of the stellar wind in Cyg X-1 via modelling of colour-colour diagrams
E. V. Lai, B. De Marco, Y. Cavecchi +11
Cygnus X-1 is a high mass X-ray binary where accretion onto the black hole is mediated by the stellar wind from the blue supergiant companion star HDE 226868. Depending on the posi…
Thermal instability as a constraint for warm X-ray corona in AGN
Dominik Gronkiewicz, Agata Różańska, Pierre-Olivier Petrucci +1
Context. Warm corona is a possible explanation for Soft X-ray Excess in Active Galactic Nuclei (AGN). This paper contains self consistent modeling of both: accretion disk with opti…
Deep absorption in SDSS J110511.15+530806.5
Marcin Marculewicz, Marek Nikolajuk, Agata Różańska
We study the origin of the anomalous deep absorption in a spectrum of the SDSS J110511.15+530806.5 distant quasar (z=1.929) obtained by the Sloan Digital Sky Survey in Data Release…
The X-ray spectral-timing contribution of the stellar wind in the hard state of Cyg X-1
E. V. Lai, B. De Marco, A. A. Zdziarski +6
The clumpy stellar wind from the companion star in high mass X-ray binaries causes variable, partial absorption of the emission from the X-ray source. We studied XMM-Newton observa…
Models of the iron K_alpha fluorescence line and the Compton shoulder in irradiated accretion disk spectra
Agata Różańska, Jerzy Madej
We present a full set of model atmosphere equations for the accretion disk around a supermassive black hole irradiated by hard X-ray lamp of power-law spectral distribution. Model…
