Abstract The study of hard X-ray emission (i.e. energy above 20 keV) of Seyfert galaxies is a powerful tool for extracting information on the intrinsic source emission properties as luminosity and spectral shape of the sources and on the intervening medium. Observations and measurements are fundamental for the study and understanding of the emission mechanisms operating in this type of objects and for testing unified models.At lower energies, we can obtain information on column densities, ionization and abundances of the surrounding matter which probe the environment around the central engine.We require one observation of 300 ks of the brightest Seyfert 2 galaxy NGC 4945. This observation will provide a good detection of the high energy spectra of NGC 4945, as well as Cen A and NGC 4507 present in its field of view, allowing us precise spectral (primary power law, reflection, cutoff) and variability studies of these three bright Seyfert 2 galaxies.

Mission Description The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
