Contributions of massive stars and classical novae to Galactic 26Al
Manja L. Zimmerer, Thomas Siegert, Niklas C. Bauer +11
The radioactive isotope 26Al is believed to be mainly produced by massive stars and ejected into the interstellar medium through their winds and supernovae. Due to its lifetime of…
Search for Axion-Like Particles from Nearby Pre-Supernova Stars
Saurabh Mittal, Thomas Siegert, Francesca Calore +7
Axion-like particles (ALPs) are hypothetical pseudoscalar bosons that arise in many extensions of the Standard Model and are well-motivated dark matter candidates. Nearby massive s…
Imaging the positron annihilation line with 20 years of INTEGRAL/SPI observations
Hiroki Yoneda, Thomas Siegert, Saurabh Mittal
The e e annihilation line at 511 keV provides a unique probe for studying the distribution and origin of positrons in our Galaxy. The SPI spectrometer on INTEGRAL has obser…
Gamma-ray line emission from the Local Bubble
Thomas Siegert, Michael M. Schulreich, Niklas Bauer +3
Deep-sea archives that include intermediate-lived radioactive particles suggest the occurrence of several recent supernovae inside the present-day volume of the…
