Modelling the behaviour of accretion flows in x-ray binaries (2007)
Journal Article
Done, C., Gierlinski, M., & Kubota, A. (2007). Modelling the behaviour of accretion flows in x-ray binaries. Astronomy and Astrophysics Review, 15(1), 1-66. https://doi.org/10.1007/s00159-007-0006-1

We review how the recent increase in X-ray and radio data from black hole and neutron star binaries can be merged together with theoretical advances to give a coherent picture of the physics of the accretion flow in strong gravity. Both long term X-r... Read More about Modelling the behaviour of accretion flows in x-ray binaries.

Analysing the atolls: X-ray spectral transitions of accreting neutron stars. (2007)
Journal Article
Gladstone, J., Done, C., & Gierlinski, M. (2007). Analysing the atolls: X-ray spectral transitions of accreting neutron stars. Monthly Notices of the Royal Astronomical Society, 378(1), 13-22. https://doi.org/10.1111/j.1365-2966.2007.11675.x

We systematically analyse all the available X-ray spectra of disc accreting neutron stars (atolls and millisecond pulsars) from the RXTE data base. We show that while all these have similar spectral evolution as a function of mass accretion rate, the...

What is the origin of the soft excess in active galactic nuclei? (2007)
Journal Article
Sobolewska, M., & Done, C. (2007). What is the origin of the soft excess in active galactic nuclei?. Monthly Notices of the Royal Astronomical Society, 374(1), 150-158. https://doi.org/10.1111/j.1365-2966.2006.11117.x

We investigate the nature of the soft excess below 1 keV observed in active galactic nuclei. We use the XMM–Newton data of the low-redshift, optically bright quasar, PG 1211+143, and we compare it with the narrow-line Seyfert 1 galaxy, 1H 0707−495, w...
