Constraints on positron annihilation kinematics in the inner Galaxy
Thomas Siegert, Roland M. Crocker, Roland Diehl +4
The annihilation of cosmic positrons () with electrons in the interstellar medium (ISM) results in the strongest persistent gamma-ray line signal in the sky. For 50 years, thi…
INTEGRAL results on the electromagnetic counterparts of gravitational waves
S. Mereghetti, V. Savchenko, C. Ferrigno +18
Thanks to its high orbit and a set of complementary detectors providing continuous coverage of the whole sky, the INTEGRAL satellite has unique capabilities for the identification…
Positron Annihilation in the Milky Way and beyond
Thomas Siegert
The electron-positron annihilation gamma-ray signal at 511 keV in the Milky Way is investigated towards a possible dark matter interpretation. If all bulge positrons were created b…
Positron annihilation signatures associated with the outburst of the microquasar V404 Cygni
Thomas Siegert, Roland Diehl, Jochen Greiner +7
Microquasars are stellar-mass black holes accreting matter from a companion star and ejecting plasma jets at almost the speed of light. They are analogues of quasars that contain s…
26Al kinematics: superbubbles following the spiral arms? Constraints from the statistics of star clusters and HI supershells
Martin G. H. Krause, Roland Diehl, Yiannis Bagetakos +6
High energy resolution spectroscopy of the 1.8 MeV radioactive decay line of 26Al with the SPI instrument on board the INTEGRAL satellite has recently revealed that diffuse 26Al ha…
