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…
The Al Gamma-ray Line from Massive-Star Regions
Thomas Siegert, Roland Diehl
The measurement of gamma rays from the diffuse afterglow of radioactivity originating in massive-star nucleosynthesis is considered a laboratory for testing models, when specific s…
Search for 511 keV Emission in Satellite Galaxies of the Milky Way with INTEGRAL/SPI
Thomas Siegert, Roland Diehl, Aaron C. Vincent +3
The positron annihilation gamma-ray signal in the Milky Way (MW) shows a puzzling morphology: a very bright bulge and a very low surface-brightness disk. A coherent explanation of…
Gamma-ray lines from SN2014J
Thomas Siegert, Roland Diehl
On 21 January 2014, SN2014J was discovered in M82 and found to be the closest type Ia supernova (SN Ia) in the last four decades. INTEGRAL observed SN2014J from the end of January…
Early 56Ni decay γ-rays from SN2014J suggest an unusual explosion
Roland Diehl, Thomas Siegert, Wolfgang Hillebrandt +7
Type-Ia supernovae result from binary systems that include a carbon-oxygen white dwarf, and these thermonuclear explosions typically produce 0.5 M_solar of radioactive 56Ni. The 56…
