We propose a multi-year program of ultra-deep observations of the M81 extragalactic field. This survey will constitute INTEGRAL legacy for the study of the AGN population at low hard X-ray fluxes and provide unique synergy with the upcoming all-sky survey by the eROSITA and ART-XC telescopes onboard the Spectrum-Roentgen-Gamma spacecraft. We ask for 5 Ms observations to be performed in the standard 5x5 dithering pattern during 2019-2020. We are planning to ask for an additional 5 Ms after completion of this proposal.

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.
