Polarization in the lamp-post geometry of the compact corona illuminating a black-hole accretion disc

[presentation]

The lamp-post geometry was in the past suggested to explain the properties of the relativistic broad iron line. It naturally gives the illumination pattern of the disc and it is claimed that it can explain the timing properties of the observed spectra. The detailed study of the polarization in reflection scenario may be important also for resolving the reflection-absorption dispute as two scenarios explaining the spectral properties of AGN in 2-10keV energy range.
In this talk the main assumptions and results for the neutral disc and unpolarized primary radiation will be summarized. New figures depicting the polarization angle and polarized flux at the detector will be shown to clarify the dependence of the polarization properties on the primary source height and observer inclination.
