... arXiv.org . astro-ph . ... We fit the near-infrared to radio spectral energy distributions of 30 luminous and ultra-luminous infrared galaxies with pure starburst models or models that include both starburst and AGN components to determine important physical parameters for this population of objects. In particular we constrain the optical depth towards the luminosity source, the star formation rate, the star formation efficiency and the AGN fraction. ...

... In particular, with the spectrometer SPI (20 keV-8 MeV), we detect in three observations an emission extending above 200 keV and for the first time even up to 350 keV for a neutron star LMXRB, GS 1826-24. ... The additional component above 200 keV is most probably of non-thermal origin. ... Figure 1. ... We reveal with SPI a hard tail up to 220 keV for 4U 1812-12 (Figure 1) and even up to 350 keV for GS 1826-24 (Figure 2), representing the hardest emission ever detected for a Neutron Star LMXRB. ...
