Abstract Cas A and Tycho are remnants of a core-collapse and type Ia supernova, respectively. Radioactive 44Ti has been observed from these two relatively young supernova remnants, and is believed to originate from the deep interiors of supernova explosions, representing physical conditions that are otherwise difficult to explore, if at all.Here we propose to simultaneously observe Cassiopeia A and Tycho in order to (1) bring Cas A results to sufficient quality for line shape and line ratio tests that can probe inner ejecta kinematics in unique ways, and (2) obtain sufficient exposure for Tycho to confirm the results reported from other instruments in the hard X-ray range. 44Ti nucleosynthesis is assumed to occur in alpha-rich freeze-out from Si burning or NSE burning, and was believed to be characteristic for core-collapse interiors. However in the Galaxy feewer 44Ti bright sources are seen than expected from core-collapse supernova statistics. Moreover, the detection of 44Ti from Tycho, a SN Ia remnant, adds to the puzzle of 44Ti synthesis and the origins of cosmic 44Ca. Additionally, the survey in 511 keV emission from positron annihilation with INTEGRAL has shown the disk being a rather faint source of positron annihilation emission, leading to the question if positrons from radioactive decays of + unstable isotopes may be contained in their sources and not leak out into interstellar medium of the Galaxys disk. Our planned observations will (4) constrain any local positron annihilation in the remnant itself, thus possibly explain the disk faintness in 511 keV gamma-rays.

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.
