Constraining dark matter properties with SPI
Using the high-resolution spectrometer SPI on board the International Gamma-Ray Astrophysics Laboratory (INTEGRAL), we search for a spectral line produced by a dark matter (DM) particle with a mass in the range 40 keV < MDM < 14 MeV, decaying in the DM halo of the Milky Way. To distinguish …
