The Compton Spectrometer and Imager is an upcoming NASA space telescope in the MeV range. COSI's primary science goals include precisely mapping nuclear line and positron annihilat…
Enhancing Compton telescope imaging with maximum a posteriori estimation: a modified Richardson-Lucy algorithm for the Compton Spectrometer and Imager
Hiroki Yoneda, Thomas Siegert, Israel Martinez-Castellanos +23
We present a modified Richardson-Lucy (RL) algorithm tailored for image reconstruction in MeV gamma-ray observations, focusing on its application to the upcoming Compton Spectromet…
Proton Radiation Damage and Annealing of COSI p-type Cross-strip HPGe Detectors
Sophia E. Haight, Steven E. Boggs, Gabriel Brewster +7
In order to understand the effects of a space radiation environment on cross-strip germanium detectors, we investigated the effects of high-energy proton damage on a COSI detector…
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…
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…

John A. Tomsick, Steven E. Boggs, Andreas Zoglauer +72
The Compton Spectrometer and Imager (COSI) is a NASA Small Explorer (SMEX) satellite mission in development with a planned launch in 2027. COSI is a wide-field gamma-ray telescope…
The cosipy library: COSI's high-level analysis software
Israel Martinez-Castellanos, Savitri Gallego, Chien-You Huang +72
The Compton Spectrometer and Imager (COSI) is a selected Small Explorer (SMEX) mission launching in 2027. It consists of a large field-of-view Compton telescope that will probe wit…
Characterizing and correcting electron and hole trapping in germanium cross-strip detectors
Sean N. Pike, Steven E. Boggs, Jacqueline Beechert +4
We present measurements of electron and hole trapping in three COSI germanium cross-strip detectors. By characterizing the relative charge collection efficiency (CCE) as a function…
Detection of the 511 keV Galactic positron annihilation line with COSI
Carolyn A. Kierans, Steven E. Boggs, Andreas Zoglauer +10
The signature of positron annihilation, namely the 511 keV -ray line, was first detected coming from the direction of the Galactic center in the 1970's, but the source of Galact…
