Scientific paper

The recent detection of a supernova remnant in the light of the 1157 keV γ-ray decay line of 44Ti with COMPTEL underlines the importance of this method in detecting young supernova remnants. The prospects for the observation of near-by supernova remnants in the γ-rays from the 44Ti decay will be presented using the latest information about the spectral resolution and the expected background of the spectrometer SPI on-board INTEGRAL. Observation times for various candidate objects are estimated, taking into account the uncertainties in distances, expansion velocities, source strengths and instrumental parameters. We compare different estimations based on the published sensitivity of the instrument SPI.
