Resum

X-ray observations are essential for studying accretion by compact objects. To understand the processes in the vicinity of accreting black holes, the spectral and temporal analysis of their X-ray emission is crucial. Studies of Active Galactic Nuclei and Galactic black holes are complementary. The analysis of the extragalactic source NGC 1052 is presented and a transition between spectral states of the bright Galactic X-ray source Cygnus X-1 is discussed.
