Gamma-ray Emission of 60Fe and 26Al Radioactivities in our Galaxy
W. Wang, T. Siegert, Z. G. Dai +7
The isotopes Fe and Al originate from massive stars and their supernovae, reflecting ongoing nucleosynthesis in the Galaxy. We studied the gamma-ray emission from the…
Vertical position of the Sun with -rays
Thomas Siegert
We illustrate a method for estimating the vertical position of the Sun above the Galactic plane by -ray observations. Photons of -ray wavelengths are particularly well suited…
Comparing simulated Al maps to gamma-ray measurements
Moritz M. M. Pleintinger, Thomas Siegert, Roland Diehl +4
Context. The diffuse gamma-ray emission of at 1.8 MeV reflects ongoing nucleosynthesis in the Milky Way, and traces massive-star feedback in the interstellar medium…
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…
Positron Annihilation in the Galaxy
Carolyn A. Kierans, John F. Beacom, Steve Boggs +27
The 511 keV line from positron annihilation in the Galaxy was the first -ray line detected to originate from outside our solar system. Going into the fifth decade since the disc…
Background modelling for -ray spectroscopy with INTEGRAL/SPI
Thomas Siegert, Roland Diehl, Christoph Weinberger +3
The coded-mask spectrometer-telescope SPI on board the INTEGRAL observatory records photons in the energy range between 20 and 8000 keV. A robust and versatile method to model the…
