| Abstract: |
The X-ray emission from galactic black holes and Seyfert galaxies is generally understood in term of two-phase models. Such models postulate that a hot plasma (∼109 K) is cooled by inverse Compton scattering of soft X-ray photons arising from relatively colder material (∼ 107 K), in the inner part of the accretion flow. We present the first simulated broad-band spectra produced in the context of such models and taking into account the radiative coupling between the two phases. This coupling is achieved using three radiative transfer codes: a non-linear Monte-Carlo code, a photo-ionisation code TITAN and a linear Monte-Carlo code NOAR. Our treatment accounts simultaneously for energy balance and Comptonisation in the hot phase, together with reprocessing, reflection, ionisation and energy balance in the cold phase. We show that such a detailed computation of the ionization and of the reprocessing has a great influence on the escaping spectra. |
