The Fermi Gamma-Ray Burst Monitor
Charles Meegan, Giselher Lichti, P. N. Bhat +18
The Gamma-Ray Burst Monitor (GBM) will significantly augment the science return from the Fermi Observatory in the study of Gamma-Ray Bursts (GRBs). The primary objective of GBM is…
Measuring Cosmic Elements with Gamma-Ray Telescopes
Roland Diehl
Gamma-ray telescopes are capable of measuring radioactive trace isotopes from cosmic nucleosynthesis events. Such measurements address new isotope production rather directly for a…
Using population synthesis of massive stars to study the interstellar medium near OB associations
R. Voss, R. Diehl, D. H. Hartmann +5
We developed a new population synthesis code for groups of massive stars, where we model the emission of different forms of energy and matter from the stars of the association. In…
Gamma-Rays from Positron Annihilation
Roland Diehl, Mark Leising
SPI on INTEGRAL has provided spectra and a map of the sky in the emission from annihilations of positrons in the interstellar medium of our Galaxy. From high-resolution spectra we…
Gamma-Ray Line Studies of Nuclei in the Cosmos
M. Leising, R. Diehl
Gamma-ray line studies are capable of identifying radioactive tracer isotopes generated in cosmic nucleosynthesis events. Pioneering measurements were made 30 years ago with HEAO-C…
Astrophysics with Radioactive Atomic Nuclei
R. Diehl, P. von Ballmoos, S. Boggs +11
We propose to advance investigations of electromagnetic radiation originating in atomic nuclei beyond its current infancy to a true astronomy. This nuclear emission is independent…
