Integral and Rxte/Asm Observations on Igr J17098-3628 (2008)
Chen, Yu-Peng, Zhang, Shu, Schurch, Nick, Wang, Jian-Min, Collmar, Werner, Li, Ti-Pei, ...
To probe further the possible nature of the unidentified source IGR J17098-3628, we have carried out a detailed analysis of its long-term time variability as monitored by RXTE/ASM, and of its hard...
RE J1034+396: The origin of the soft X-ray excess and QPO (2008)
Middleton, Matthew, Done, Chris, Ward, Martin, Gierlinski, Marek, Schurch, Nick
The X-ray quasi-periodic oscillation (QPO) seen in RE J1034+396 is so far unique amongst AGN. Here we look at the another unique feature of RE J1034+396, namely its huge soft X-ray excess, to see if...
High Energy spectra of Seyferts and Unification schemes (2007)
Middleton, Matthew, Done, Chris, Schurch, Nick
The Unified Model of AGN predicts the sole difference between Seyfert 1 and Seyfert 2 nuclei is the viewing angle with respect to an obscuring structure around the nucleus. High energy photons above...
The Origin of the soft excess in AGN (2007)
Done, Chris, Gierlinski, Marek, Sobolewska, Malgosia, Schurch, Nick
We discuss various ideas for the origin of the soft X-ray excess seen in AGN. There are clear advantages to models where this arises from atomic processes in partially ionised rather than where it is...
