Ti-44 detection in SNR 1987A

The first detection of titanium-44 in supernova remnant 1987A. ESA’s Integral space telescope made the detection in the energy range between 65 keV and 82 keV, which brackets two emission lines produced during the decay of titanium-44, at 67.9 keV and 78.4 keV.

The detection required over 1000 hours of observation time with Integral.

Also seen in the field of view are two other bright sources of high-energy emission, the black hole binary known as LMC X-1 and the pulsar PSR B0540-69.
