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...

Black hole spin in GRS 1915+105. (2006)
Journal Article
Middleton, M., Done, C., Gierliński, M., & Davis, S. (2006). Black hole spin in GRS 1915+105. Monthly Notices of the Royal Astronomical Society, 373(1), 1004-1012. https://doi.org/10.1111/j.1365-2966.2006.11077.x

Microquasars are galactic black hole binary systems with radio jets which can sometimes be spatially resolved to show superluminal motion. The first and best known of this class of objects is GRS 1915+105, the brightest accreting source in our Galaxy... Read More about Black hole spin in GRS 1915+105..

Truncated disc versus extremely broad iron line in XTE J1650-500 (2006)
Journal Article
Done, C., & Gierliński, M. (2006). Truncated disc versus extremely broad iron line in XTE J1650-500. Monthly Notices of the Royal Astronomical Society, 367(2), 659-668. https://doi.org/10.1111/j.1365-2966.2005.09968.x

There is growing evidence from both spectral and timing properties that there is a truncated inner accretion disc in low mass accretion rate Galactic black hole systems. The detection of extremely smeared relativistic iron lines in some of these syst... Read More about Truncated disc versus extremely broad iron line in XTE J1650-500.
