Galactic Population Synthesis of Radioactive Nucleosynthesis Ejecta

Thomas Siegert, Moritz M. M. Pleintinger, Roland Diehl +3

Diffuse gamma-ray line emission traces freshly produced radioisotopes in the interstellar gas, providing a unique perspective on the entire Galactic cycle of matter from nucleosynt…

Diffuse Galactic emission spectrum between 0.5 and 8.0 MeV

Thomas Siegert, Joanna Berteaud, Francesca Calore +2

The last measurement of the diffuse emission spectrum of the Milky Way in the megaelectronvolt (MeV) photon energy range was performed by CGRO/COMPTEL more than 20 years ago. We re…

Hoinga: A supernova remnant discovered in the SRG/eROSITA All-Sky Survey eRASS1

W. Becker, N. Hurley-Walker, Ch. Weinberger +4

Supernova remnants (SNRs) are observable for about 6-15x10^4 years before they fade into the Galactic interstellar medium. With a Galactic supernova rate of approximately two per c…

ejecta in young supernova remnants

Christoph Weinberger, Roland Diehl, Moritz M. M. Pleintinger +2

Context: Tracing unstable isotopes produced in supernova nucleosynthesis provides a direct diagnostic of supernova explosion physics. Theoretical models predict an extensive variet…

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…

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…

Gamma-Ray Observations of Nova Sgr 2015 No. 2 with INTEGRAL

Thomas Siegert, Alain Coc, Laura Delgado +11

INTEGRAL observed the nova V5668 Sgr around the time of its optical maximum on March 21, 2015. Studies at UV wavelengths showed spectral lines of freshly produced Be-7. This could…

INTEGRAL/SPI -ray line spectroscopy

Roland Diehl, Thomas Siegert, Jochen Greiner +7

INTEGRAL/SPI is a space-based coded mask telescope featuring a 19-element Germanium detector array for high-resolution gamma-ray spectroscopy, encapsulated in a scintillation detec…
