Pre-flight Background Estimates for COSI
Savitri Gallego, Uwe Oberlack, Jan Lommler +14
The Compton Spectrometer and Imager (COSI) is a Compton telescope designed to survey the 0.2 - 5 MeV sky, consisting of a compact array of cross-strip germanium detectors. It is pl…
Benchmarking of Geant4 simulations for the COSI Anticoincidence System
Alex Ciabattoni, Valentina Fioretti, John A. Tomsick +10
The Compton Spectrometer and Imager (COSI) is an upcoming NASA Small Explorer satellite mission, designed for all-sky observations in the soft gamma-ray domain with the use of germ…
Detection of positron in-flight annihilation from the Galaxy
Jürgen Knödlseder, Karim Sabri, Pierre Jean +3
Although the annihilation of positrons towards the Galactic centre was established more than 50 years ago through the detection of a 511 keV -ray line, the origin of the positr…
Bottom-up Background Simulations of the 2016 COSI Balloon Flight
Savitri Gallego, Uwe Oberlack, Jan Lommler +8
The Compton Spectrometer and Imager (COSI) is a Compton telescope designed to survey the 0.2-5 MeV sky, consisting of a compact array of cross-strip germanium detectors. As part of…
Imaging and Spectral Fitting of Bright Gamma-ray Sources with the COSI Balloon Payload
Jarred M. Roberts, Steven Boggs, Thomas Siegert +17
The Compton Spectrometer and Imager balloon payload (COSI-Balloon) is a wide-field-of-view Compton -ray telescope that operates in the 0.2 - 5 MeV bandpass. COSI-Balloon had a…
