ComPair-2: A Next Generation Medium Energy Gamma-ray Telescope Prototype
Regina Caputo, Carolyn Kierans, Nicholas Cannady +30
Many questions posed in the Astro2020 Decadal survey in both the New Messengers and New Physics and the Cosmic Ecosystems science themes require a gamma-ray mission with capabiliti…
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 s…
Characterizing hole trap production due to proton irradiation in germanium cross-strip detectors
Sean N. Pike, Steven E. Boggs, Gabriel Brewster +6
We present an investigation into the effects of high-energy proton damage on charge trapping in germanium cross-strip detectors, with the goal of accomplishing three important meas…
Towards a response function for the COSI anticoincidence system: preliminary results from Geant4 simulations
Alex Ciabattoni, Valentina Fioretti, John Tomsick +9
The Compton Spectrometer and Imager (COSI) is an upcoming NASA Small Explorer satellite mission scheduled for launch in 2027 and designed to conduct an all-sky survey in the energy…
Across the soft gamma-ray regime: utilizing simultaneous detections in the Compton Spectrometer and Imager (COSI) and the Background and Transient Observer (BTO) to understand astrophysical transients
Hannah C. Gulick, Eliza Neights, Samer Al Nussirat +17
The Compton Spectrometer and Imager (COSI) is a NASA funded Small Explorer (SMEX) mission slated to launch in 2027. COSI will house a wide-field gamma-ray telescope designed to sur…
Atmospheric Response for MeV Gamma Rays Observed with Balloon-Borne Detectors
Chris Karwin, Carolyn Kierans, Albert Shih +9
The atmospheric response for MeV gamma rays (~ 0.1 - 10 MeV) can be characterized in terms of two observed components. The first component is due to photons that reach the detector…
