Is the soft excess in active galactic nuclei real? (2004)
Journal Article
Gierlinski, M., & Done, C. (2004). Is the soft excess in active galactic nuclei real?. Monthly Notices of the Royal Astronomical Society, 349(1), L7-L11. https://doi.org/10.1111/j.1365-2966.2004.07687.x

We systematically analyse all publicly available XMM–Newton spectra of radio-quiet PG quasars. The soft X-ray excess in these objects is well modelled by an additional, cool, Compton scattering region. However, the remarkably constant temperature der...

Radiative processes, spectral states and variability of black-hole binaries (2004)
Journal Article
Zdziarski, A., & Gierlinski, M. (2004). Radiative processes, spectral states and variability of black-hole binaries. Progress of theoretical physics. Supplement, 155, 99-119

We review radiative processes responsible for X-ray emission in hard(low) and soft (high) spectral states of black-hole binaries. The main process in the hard state appears to be scattering of blackbody photons from a cold disk by thermal electrons i...

Black hole accretion discs: reality confronts theory (2004)
Journal Article
Gierliński, M., & Done, C. (2004). Black hole accretion discs: reality confronts theory. Monthly Notices of the Royal Astronomical Society, 347(3), 885-894. https://doi.org/10.1111/j.1365-2966.2004.07266.x

Disc spectra from highly luminous black hole binaries are observed to be rather simple, despite theoretical predictions to the contrary. We collate the disc-dominated spectra from multiple observations of 10 separate sources and show that they are co... Read More about Black hole accretion discs: reality confronts theory.
