Abstract We propose a deep 3.0 Msec exposure of the Large Magellanic Cloud in order to finally detect the flux from SN 1987A in the direct-escape lines of radioactive $^{44}$Ti (lines at 67.9, 78.4 and 511 keV), to study the possible hard X-ray emission produced by cosmic-rays accelerated in the ejecta blast wave interacting with the ``inner equatorial ring of circumstellar material of SNR 1987A, to search for hard emission from the stellar remnant of this supernova (or significantly improve the existing upper limit). In addition, we will try to detect electron-positron annihilation line from the dark bulge of the LMC (testing the hipotesis that it can be produced in the LMC and in the Galactic center by dark matter annihilation). We will also investigate a number of compact X-ray sources present in the field and search for new X-ray sources and transients. Observation of the LMC make the best use of the unique INTEGRAL capabilities and undoubtedly are the most efficient investment of its precious observing time. Should this proposal be accepted, the data will be made available during the proprietary period to scientists of major astrophysical institutions of Russia.

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.
