TL;DR: High spectral resolution measurements of 26Al emission at 1808.65 keV demonstrate that the 26Al source regions corotate with the Galaxy, supporting its Galaxy-wide origin and determining a present-day equilibrium mass of 2.8 (± 0.8) solar masses of 27Al.

TL;DR: SPI as discussed by the authors is a high spectral resolution gamma-ray telescope on board the ESA mission INTEGRAL (International Gamma Ray Astrophysics Laboratory), which consists of an array of 19 closely packed germanium detectors surrounded by an active anticoincidence shield of BGO.

TL;DR: Positron production at this level from hard LMXBs in the Galactic bulge would reduce (and possibly eliminate) the need for more exotic explanations, such as those involving dark matter.

TL;DR: The enhanced X-ray Timing and Polarimetry mission—eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism and will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects.

TL;DR: The beam and detector used for the NA48 experiment, devoted to the measurement of Re(e′/e) and neutral hyperon decays, are described in this paper.
