Abstract We propose to perform with INTEGRAL a long monitoring of 10 observations of 200 ks each of the Seyfert 1 galaxy Mkn 509 simultaneously with an already accepted XMM-Newton monitoring (10 pointings of 60 ks each spaced by 4 days) of this source.This will provide for the first time a very broad band spectral follow-up, from the UV to the soft $\gamma$-ray, of a Seyfert galaxy on a month time scale. This will permit: 1) to disentangle the different spectral components in the UV, soft X, medium X-ray and $\gamma$-ray bands, 2) to test different origin of the primary continuum by determining whether the shape of the X-ray continuum is related to the UV intensity 3) to elucidate the origin of the soft X-ray excess and 4) to determine the shape and variability of the Fe 6-7 KeV emission complex and it relation to the high energy ($>$ 10 keV) band. The proposed simultaneous INTEGRAL/XMM-Newton long monitoring of one of the brightest Seyfert galaxies is a unique opportunity to put firm conclusionson the still largely unknown nature and origin of the UV/X-ray/$\gamma$-ray emission of this class of objects.

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.
